Isoleucine is an essential amino acid which is one of the three Branched-chain amino acids ( Leucine, isoleucine, and valine ) that is used in the biosynthesis of proteins.

Amino acids are one of the organic compounds that combine to form proteins, Which is an essential part of many processes in the human body.

Isoleucine is also one of the nine essential amino acids in the human body which is present in our dietary proteins.

Role of Isoleucine in our body

Isoleucine has one of the very important role to assisting a wound healing, detoxification of nitrogenous waste, stimulating immune function, and promoting secretion of formation and regulating blood sugar and energy levels.
