Molecular Structure:

Property:

The melting point of Isoleucine is168-170 ºC and the sublimation is 168-170 ºC. The alpha of Isoleucine is 41 º (c=4, 6N HCl) and the water solubility is 41.2 g/l (50 ºC).

Isoleucine (abbreviated as Ile or I) is an α-amino acid with the chemical formula HO2CCH(NH2)CH(CH3)CH2CH3. Isoleucine is an essential amino acid, which means that humans cannot synthesize it, so Isoleucine 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 presents in nature exists in one enantiomeric form, (2S,3S)-2-Amino-3-Methylpentanoic Acid.

Usage:

Isoleucine can promote protein synthesis and improve the level of growth homone and insulin, to maintain balance in the body. Isoleucine can increase the body immune funtion, treat mental disorders, promote an increase in appetite and has the role of anti-anemia. Mainly in medicine, food industry, Isoleucine protects the liver. Liver role in muscle protein metabolism is extremely important. If lack, there will be physical failure, such as the state of coma. Isoleucine is also for the amino acid infusion or oral nutritional additives.

Package and Storage:

Isoleucine is packed in 25kg fiber drum and stored in cool and air place.
