The Difference Between Phenols and Carotenoids

The Difference Between Phenols and CarotenoidsAt some point or another, many students of biology and chemistry to find themselves feeling out of their depth when it comes to the essential elements of chemistry, like the basic difference between phenols and the aromatic rings. Phenols are actually essential components of the body, but instead of being the ring formation that some would have you believe, phenols are complex aromatic rings. You may not have the full comprehension of this concept at first, but understanding this simple concept will help you feel more comfortable with your knowledge in chemistry and biology.Phenols are a rather important aspect of biology and chemistry. Phenol is simply a group of phenyl groups bound together in a tight bond. Although phenols are often thought of as simply occurring naturally in plants, they are actually much more important in their own right than this. For example, phytochemicals, the compounds found in plants that can be beneficial for humans, have phenolic structures, and these are just two examples of the many forms of phenols.These rings are formed when two different phenols are joined together with two rings attached to each other, usually through hydroxyl groups on either side of the ring. Because these rings are so important, they are typically referred to as molecular complexes, but while this is technically correct, this does not really accurately define what the molecules are used for. In fact, a phenol is actually an acid containing phenyl groups attached to each other in order to form a ring.Phytochemicals are very important in the human body, especially because they can act as antioxidants. They are present in a wide variety of foods, including fruits, vegetables, and nuts, and help keep cells healthy and living at optimal levels. Another very important function of phytochemicals is that they are associated with a wide range of different diseases, including heart disease, cancer, Alzheimer's disease, a nd Parkinson's disease.While a molecular complex is important, phenols are the most important. Phenol molecules are much more commonly found in humans than in any other animal, and even plants produce a small amount of phenols, usually as flavonoids. Interestingly enough, the molecule that is used as the chemical symbol for this group of compounds is known as PDCA-24. This molecule has a function in biology and chemistry in that it functions as a source of energy, and is also a major constituent of many enzymes.But, what makes phenols unique is that they can provide specific antioxidant activity. Many other antioxidants are able to function by simply attaching to the protein's surface, and are able to do little else. When phenol attaches to the protein, it can attach to the membrane that surrounds the protein and thus supply it with free electrons, which enables it to do its job.Essential vitamins such as vitamin E, C, and B are also available in a variety of forms. While some of th ese forms can provide other antioxidants besides the ones noted above, the fact that all forms are able to provide vital vitamins is the reason why they are considered essential. Vitamin B12 is vital for the proper functioning of the nervous system and is also important for vision, nerve transmission, and metabolism.While phenols are a component of all life on earth, there are a few different types of phenols that are able to be broken down to produce various products. Some of these products are necessary, while others are not. The types of phenols that are important to humans are known as phenolic acids, and these can be broken down into various forms for use in the human body.

Simplest Form Fraction

Simplest Form Fraction Fraction is usually written in the p/q form. Here p is the numerator and q is the denominator. The denominator of a fraction cannot be equal to zero i.e. q not equal to zero. Fraction are very commonly used and very important form of representation of numbers. Fraction are included in different equations expressions in numerical and algebraic expressions. Some fractions can be further simplified according to the requirement. Different mathematical operations can be used to simplify and solve a given fraction. Example 1: Simplify the fraction 300/250 to its simplest form? In the given fraction 300 /250, 300 is the numerator and 250 is the denominator. The fraction can be further simplified. Factoring the numerator and denominator gives: 300 = 2 * 2 * 3 * 5 * 5 250 = 2 * 5 * 5 * 5 Now when these numbers are written as fractions there are some common factors. Therefore cancelling the common factors 300 / 250 can be written as 6 /5. Hence the simplified fraction of 300 /250 is 6/5. Example 2: Simplify the fraction 28 / 40 to its simplest form? In the given fraction 28 /40, 28 is the numerator and 40 is the denominator. The fraction can be further simplified. Factoring the numerator and denominator gives. 28 = 2 * 2 * 7 40 = 2 * 2 * 2 * 5 Now when these numbers are written as fractions there are some common factors. Therefore cancelling the common factors 28/ 40 can be written as 7/10. Hence the simplified fraction of 28/40 is equal to 7/10.

How To Succeed In Science And Engineering

How To Succeed In Science And Engineering Science, technology, engineering and math (STEM programs) have historically been the toughest majors, with science and engineering leading the way, according to an article in the New York Times. However, the STEM fields also have the largest potential to boost Americas economy, and that is why President Obama is placing a major emphasis on these programs. But, its not going to be easy. Politicians and educators have been trying to improve students test scores in the STEM fields for years, and they are running out of ideas. Currently, American students trail behind many foreign countries in STEM fields, and Washington is hoping to become more globally competitive through these fields. That is why Obama and industry groups have called on colleges to produce 10,000 more engineers a year and 100,000 new teachers with majors in STEM programs. Obama is hoping this can put America on the leading edge of STEM innovation. Step one: start early. Obama has put grade school students under the microscope, analyzing their STEM scores more closely than any other group and always promoting the fields as career options. His efforts have produced some promising results, as more college freshmen are becoming interested in STEM programs. However, for too many, the interest stops during their freshmen years because they cannot meet the demands of these rigorous courses. Nearly 40% of students planning engineering and science majors end up changing their major or failing to get any degree even though these students tend to have the highest SAT scores. Also, earning a STEM degree is becoming increasingly more challenging. Many freshmen level STEM classes are actually designed to weed students out, and unfortunately, they hit their mark far too often. Making these classes easier is not the answer. So, the Association of American Universities, which represents 61 of the largest research institutions, announced a five-year initiative to encourage professors to employ more interactive teaching techniques a plan many educators are hoping will increase student interest. Educators are trying to make the entry-level classes more about practical, real-world application and less about memorizing equations and facts. Also, they want their classes to be more discussion based instead professors just lecturing. But there are other factors affecting these programs, factors beyond the STEM programs control. Grade inflation in the humanities and social sciences has attracted a lot of students, even some STEM students because their grades historically tend to be the lowest among freshmen. College GPA has always been perceived as a strong indicator for early career success; however, a 3.5 in an English program is not necessarily better than a 2.5 in a STEM program. Many students transfer out of STEM classes to achieve a higher GPA, thinking they will find better jobs out of college. But, thats not exactly true because there are many more open jobs in STEM fields. The struggle has always been getting students to plunge through the difficult entry-level classes. But right now, a STEM degree is one of the most valuable degrees a student can have.

4 Singing Exercises to Practice Dynamics

4 Singing Exercises to Practice Dynamics Suzy S. As a singer, understanding and utilizing dynamics can turn a mediocre performance into a great one. Read on to learn some singing exercises to practice, as shared by Augustine, FL voice teacher  Heather L... Dynamics is a word that comes from the Greek word dynamo, meaning power. In the context of general music, we use it as a term for how loud or soft sounds are. Dynamics can make or break a song. Frankly, in the world of singing, sometimes the lack of or presence of dynamics can make a difference in whether a singer is regarded as great or not. Think of the best singers in the world and Ill bet that many have a tremendous sense of dynamics. The improvement of the use of dynamics in our singing voices comes right down to a word that I dont typically like to use as a voice teacher: control. The simple passing use of this word can often, maybe subconsciously, cause a singer to tense and strain. Control, however, is truly the thing that enables us to do much with our voices. Just make sure to maintain a free and open sound as you incorporate the concept of control in the following singing exercises. Learn and Practice Messa di Voce Perhaps the best singing exercise to help improve your vocal dynamics is messa di voce, an Italian phrase meaning place the voice.  To sing a messa di voce, you sustain one single pitch, getting louder, then softer.  The proper musical terms for getting louder and softer are crescendo and diminuendo, respectively.  Decrescendo is a word created in modern times to mean become softer, but it is not an Italian word or a proper musical term.  When using this exercise, be sure, as always, to use a warm, resonant sound and to stay connected to your breath. Remember, your sound begins at the bottom of the pelvic floor. Keep your shoulders floating in place; do not allow them to rise. Lip Trill Like a Revving Engine Another singing exercise to practice dynamics is singing lip trills, or lip bubbles, using messa di voce.  This is a great one that I learned from Celine Dion. Begin with a low breath, filling up your torso all the way around. Start at a comfortable low/middle position in your voice, trill up to a comfortable high point, and begin to sail down to your lowest register. As you slowly sail down in pitch, make stops along the way. On those stops, crescendo and then diminuendo. Itll sound a lot like a old drag car revving its engine! Not only does this singing exercise improve your ability to sing dynamically, but it will also help to warm up and strengthen your singing muscles. Laugh Out Loud Speaking of strengthening exercises, its essential that the muscles of your torso are strong enough for the control thats needed for great dynamics. Sing short ha, ha, ha sequences on a descending scale, making each ha very short, but warm and round. Youll notice quite a jumpy motion from your tummy as you instinctively work to produce short bursts of air. Yow-wow-wow In this exercise, youll sing a single pitch on yow-wow-wow with a loose, open jaw, as if youve just touched a hot stove. This loosens the face, especially your joints, which is vitally important in preventing tension. Lastly, remember that singing dynamics comes not only from phonationthe pitched sounds that our vocal folds producebut also from articulation. Our articulators are our teeth, our tongue, and our lips. To be clear, crisp articulation should be an inherent part of your singing voice.  You can use it, though, to sound even louder or softer than your phonation is. And as always, be yourself and sing with your own voice. Heather L. teaches singing, piano, acting, and more in Saint Augustine, FL, as well as through online lessons.
