Isoleucine (abbreviated as Ile or I)[1] is an α-amino acid with the chemical formula HO2CCH(NH2)CH(CH3)CH2CH3. It is an essential amino acid, which means that humans cannot synthesize it, so it must be ingested. Its codons are AUU, AUC and AUA. With a hydrocarbon side chain, isoleucine is classified as a hydrophobic amino acid. Together with threonine, isoleucine is one of two common amino acids that have a chiral side chain. Four stereoisomers of isoleucine are possible, including two possible diastereomers of L-isoleucine. However, isoleucine present in nature exists in one enantiomeric form, (2S,3S)-2-amino-3-methylpentanoic acid. L-isoleucine is one of the branched chain amino acids (L-isoleucine, L-valine, and L-leucine) and is classified as an essential amino acid. This means the body cannot manufacture L-isoleucine; it must be acquired through diet or supplementation. The male adult's daily requirement is 10 mg per kg of body weight. Food sources for isoleucine include almonds, cashews and soy protein.

L leucine is soluble in formic acid, slightly soluble in water, very slightly soluble in ethanol or ether. L Leucine is an essential amino acid.

1. L leucine can be used as nutritional supplements, flavoring flavoring agent
2. L leucine effects include isoleucine and valine and work together to repair the muscle, blood glucose control, and provide energy to the body tissues. L-Leucine can increase growth hormone production and help burn visceral fat, these fats in the body due to internal, only difficult for them to produce an effective role through diet and exercise.
3. L leucine is the most effective one branched chain amino acids, can effectively prevent muscle loss, because it can be converted to a faster decomposition of glucose. Increased glucose may prevent muscle tissue damage, so it is particularly suitable for bodybuilders.
4. L Leucine helps regulate blood sugar levels because it is easily converted to glucose.
