Isoleucine and derivatives

Isoleucine (Ile) is an essential amino acid with the chemical formula C6H13NO2, belonging to the branched-chain amino acids (BCAAs). It plays key physiological functions in the body, especially in protein synthesis, energy production and regulation of the immune system. The chemical structure of isoleucine is similar to that of leucine, but differs in the structure of the side chain. In addition to being directly involved in metabolic processes, isoleucine also affects other physiological functions through its derivatives, such as α-ketoisoleucine and ketone bodies. Isoleucine plays an indispensable role in maintaining the body's energy balance, supporting muscle repair and coping with exercise stress.
