There are 20 different kinds of amino acids. Adult humans can only produce 11 of them, so the other nine must be consumed via diet. The amino acids that humans cannot produce are called essential amino acids because they are needed for the body to function.Continue Reading
The essential amino acids are histidine, threonine, isoleucine, methionine, leucine, lysine, phenylalanine, tryptophan, and valine. Arginine's nature as an essential amino acid in children is debated, some sources considering it essential and some considering it semi-essential. The nonessential amino acids are alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine and tyrosine. All amino acids are used by both plants and animals to build proteins for muscle and chemicals meant for signaling within the body.
Essential amino acids can be obtained by eating plant protein. Plants, unlike animals, are able to produce all their amino acids by themselves. However, not all of the amino acids are always found together in the same plant tissue. Frances Moore Lappe, an influential writer on vegetarian nutrition, recommends that different sources of plant protein be combined to produce what she calls a "complete" protein containing all essential amino acids, but this is not strictly necessary. Of course, protein from animals contains all essential amino acids naturally.Learn more about Organic Chemistry
Vanadium is readily alloyed with other metals, and it resists corrosion from oxygen, salt water, alkali compounds and many acids because it forms an impermeable coating of vanadium oxide in air. While it resists more thorough oxidation at low temperatures, it readily forms the important compound vanadium oxide above 660 degrees Celsius. This compound has two vanadium atoms bound to five oxygen atoms and is relatively soft and ductile.Full Answer >
The four types of macromolecules, or very large molecules, are nucleic acids, proteins, lipids and carbohydrates. All are biological polymers, except for lipids that, according to the University of New Mexico, are not considered to be made of monomers and thus are not polymers. Carbon is integral to all these types of molecules, with hydrogen, nitrogen, phosphorous and oxygen also playing a role in several of them.Full Answer >
Denatured proteins are hydrolyzed, and the peptide bonds are broken down into easily digestible amino acids. Protein supplements often contain denatured proteins to increase absorption. Athletes use denatured proteins to get supplemental protein into their muscles more quickly.Full Answer >
The four main sources of organic compounds are proteins, lipids, carbohydrates and nucleic acids. Organic compounds are molecules that are built on carbon, and they are the main chemical component of living organisms.Full Answer >
