L-Isoleucine L-lsoeucine73-32-5 Huicheng Biotechnologysupply

Isoleucine, also known as "isoleucine", is systematically named "α - amino - β - methylvaleric acid". It is one of the essential amino acids for the human body and belongs to the category of neutral fatty amino acids. There is a high content in meat. Isoleucine contains two asymmetric carbon atoms. So there are four stereoisomers. L-isoleucine is present in various proteins, but D-isoleucine is not present in proteins. L-Isoleucine is one of the essential amino acids and is nutritionally related to valine and leucine, which have similar structures. Although it is a sugar amino acid, it has a slight ketogenic effect. Alpha methylbutyryl cofactor generated from isoleucine via amino transfer and decarboxylation reaction in living organisms(Space)Enzyme A undergoes a fatty acid like decomposition to generate acetyl CoA and acetyl CoA(Space)Enzyme A, which becomes succinyl coenzyme A, enters the citric acid cycle. When synthesized by bacteria, it is known that they are composed of threonine and pyruvate dihydroxy acid alpha ketone acid.
