S-Acetyldihydrolipoamide

S-[6-Amino-6-oxo-1-(2-sulfanylethyl)hexyl] ethanethioic acid

C10H19NO2S2 (249.0857)

S-Acetyldihydrolipoamide is a thio-acetylated form of dihydrolipoamide. The molecule is commonly conjugated to lysine residues. The structure shown is the free form of the molecule. Pyruvate dehydrogenase complex. The reaction is 2-(alpha-hydroxyethyl)-TPP + lipoamide => S-acetyldihydrolipoamide + TPP [Homo sapiens], occuring in mitochondrial matrix. (reactome.org). S-Acetyldihydrolipoamide is an intermediate in alanine, aspartate and pyruvate metabolism and glycolysis/gluconeogenesis (KEGG:C01136). It is converted from 2-hydroxyethyl-THPP and lipoamide via the enzyme pyruvate dehydrogenase (EC:1.2.4.1). It is then converted to acetyl-CoA via the enzyme pyruvate dehydrogenase E2 component (dihydrolipoamide acetyltransferase) (EC:2.3.1.12). S-Acetyldihydrolipoamide is a thio-acetylated form of dihydrolipoamide. The molecule is commonly conjugated to lysine residues. The structure shown is the free form of the molecule.

Cysteinyl-Glutamine

2-[(2-Amino-1-hydroxy-3-sulphanylpropylidene)amino]-4-(C-hydroxycarbonimidoyl)butanoic acid

C8H15N3O4S (249.0783)

Cysteinyl-Glutamine is a dipeptide composed of cysteine and glutamine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
