In humans, there are nine essential amino acids. An essential amino acid is one that cannot be manufactured in the body; it must come from the food humans eat. The other 11 amino acids are considered to be nonessential.Continue Reading
The nine essential amino acids for humans are histidine, leucine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Other organisms have different essential amino acids. Nonessential acids do not need to come from food because they can be made by the body. Only 20 amino acids are used by all life forms; however, 500 different amino acids exist on Earth.
Proteins come from a string of monomers, or building blocks, called amino acids. These amino acids combine with one another to produce the large number of proteins used for various structural and functional needs in the body.Learn more about Organic Chemistry
An organic acid is an organic substance that has the properties of an acid, while inorganic acids, also known as mineral acids, come from inorganic substances. Some examples of inorganic acids include suphuric acid, hydrochloric acid, nitric acid, boric acid and hydrofluoric acid.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 >
Enzymes are organic molecular proteins composed of amino acids. At any point in time, when work is taking place within a cell, it is being accomplished by the enzymes. Their purpose is to facilitate swift chemical reactions that allow the cell to break things down or assemble things as necessary. These processes are what allow a cell to grow and reproduce.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 >
