5 天之前 · An amino acid is an organic molecule that is made up of a basic amino group (−NH 2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid.

amino acid, Any of a class of organic compounds in which a carbon atom has bonds to an amino group (―NH 2), a carboxyl group (―COOH), a hydrogen atom (―H), and an organic side group (called ―R). They are therefore both carboxylic acids and amines. The physical and chemical properties unique to each result from the properties of the R ...

2025年1月14日 · The simplest amino acid is glycine, in which R is a hydrogen atom. In a number of amino acids, R represents straight or branched carbon chains. One of these amino acids is alanine , in which R is the methyl group (―CH 3 ).

Chemists define an amino acid as any group of organic molecules that consist of a basic amino group (–NH 2), an acidic carboxyl group (–COOH), and a specific organic side chain that is unique to each amino acid. Arginine, glycine, cystine, histidine, and …
