The precise amino acid content, and the sequence of those amino acids, of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein. The chemical properties of the amino acids of proteins determine the biological activity of the protein.

Amino acids are very small biomolecules with an average molecular weight of about 135 daltons. These organic acids exist naturally in a zwitterion state where the carboxylic acid moiety is ionized and the basic amino group is protonated. ... The amino acid backbone determines the primary sequence of a protein, but the nature...

Amino acids come from protein rich sources such as meat, fish, dairy products, and vegetables such as legumes, peas, and grains. There are many types of amino acid supplements on the market. Some products claim to have a large quantity of amino acids, but come primarily from a weak protein source (such as milk).
