Isoleucine

Isoleucine is an amino acid found in proteins. In mammals, isoleucine is an essential amino acid, meaning it must be present in the diet. Isoleucine's nonpolar side chain classifies it as an aliphatic amino acid.

The more hydrophobic amino acids, like isoleucine, are usually found in the interior of a protein molecule, where they are shielded from water.
