What is an amino acid?

Answer 1

An amino acid is an organic compound containing both an amino and a carboxylic acid functional group - or any of the twenty naturally occurring α-amino acids and a variety of side chains which combine via peptide bonds to form proteins.

Answer 2

Is an organic compound that contains both a basic amino group and a carboxyl group. The alpha amino acids, in which the amino group is attached to the alpha carbon, are the building blocks (or monomers) of peptides and proteins. The amimno acids are commonly classified either as: a) neutral, basic, or acidic, or as b) nonpolar, polar and uncharged, or polar and charged, according to their structures.

Answer 3

Amino acids are organic compounds that serve as the building blocks of proteins. They contain an amino group, a carboxyl group, and a side chain, which varies among different amino acids. There are 20 standard amino acids that are commonly found in proteins.

Answer 4

protein molecules made up of small units joined together like links in a chain
