描述

The alkyl amino acid L-isoleucine is an isomer of L-leucine, differing in the position of the side chain. In L-isoleucine, the methyl group is on the b-carbon of the amino acid chain, rather than the g-carbon as in Lleucine. Isoleucine is biosynthesized from threonine through the formation of a-ketobutyrate. Isoleucine is degraded to acetyl CoA and to propionyl CoA. Isoleucine provides a source of nitrogen for transport to the liver and kidney.

The induction of apoptosis upon deprivation of isoleucine and other amino acids in two different sets of cultured cells, PC12 cells and postmitotic neurons isolated from fetal rat brains, has been studied. Isoleucine has been shown to block lysine transport in cultured chicken jejunum epithelial cells. The interaction of isoleucine with Arabidopsis thaliana threonine deaminase has been examined by biochemical and mass spectrometric studies.

A GC/MS method for the analysis of various amino acids, including isoleucine, via pyrolysis in the presence of hexamethyldisilazane has been described.
