Amino acid Amino acids are simple organic compounds made of carbon, hydrogen, oxygen, nitrogen, and, in a few cases, sulfur. Amino acids bond together to form protein molecules, the basic building blocks of all living things. Amino acids can vary widely. Only about 20 amino acids are ...

In chemistry, an α-amino acid consists of an amino group, a carboxyl group, an R-group, and a hydrogen atom which is bonded to the α-carbon. The R-group represents a side chain specific to each amino acid and 20 different kinds of side chains (varying in shape, size, charge, ...
The term limiting amino acid is also applied to those essential amino acids in a particular food, which falls short of meeting the amount required by humans. The energy needs of the body are primarily met with carbohydrates and fats. If carbohydrate and fat in the diet are low, amino acids...
The wide range of amino acid functions, including amino acid synthesis, breakdown, and transport, has provided numerous targets for the development of drugs. Amino acid-degrading enzymes such as arginase and asparaginase have been shown to exert antitumor effects in preclinical and clinical settings;...
acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2-Aminoisobutyric acid exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 2-Aminoisobutyric acid has been detected, but not quantified in, milk (cow). This...
Used in plastics, paints, cutting oils, and specialized cleaning compounds. Air & Water Reactions Water soluble. Reactivity Profile Amino-2-propanol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The ...
The selenoamino acid selenomethionine (3, SeMet, Scheme 2) is a natural component of our cells, and it is the predominant form of Se in the diet. Its role in human health is to act as a reservoir of Se due to its random incorporation into proteins instead of methionine (Burk and Hill...
