2) Amino acids are a set of 20 different molecules used to build proteins. Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active. The amino acid sequences of proteins are encoded in the genes.

One of the most illustrious of warriors, Achilles was the offspring of a sea nymph who sought to achieve immortality for her son by dipping him in the river Styx in Hades.
