DescriptionLipoamide, also known as thioctamide or lipoacin, belongs to the class of organic compounds known as lipoamides. Lipoamides are compounds containing a lipoamide moiety, which consists of a pentanamide attached to the C3 carbon atom of a 1,2-dithiolane ring. Thus, lipoamide is considered to be a fatty amide lipid molecule. Lipoamide is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Lipoamide exists in all living species, ranging from bacteria to humans. In yeast, lipoamide is involved in the metabolic pathway called the tca cycle pathway.

Enzymes

General function:
Involved in oxidoreductase activity
Specific function:
Lipoamide dehydrogenase is a component of the alpha- ketoacid dehydrogenase complexes. This includes the pyruvate dehydrogenase complex, which catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). Acts also as component of the glycine cleavage system (glycine decarboxylase complex), which catalyzes the degradation of glycine
Gene Name:
LPD1
Uniprot ID:
P09624
Molecular weight:
54009.69922
Reactions
Protein N(6)-(dihydrolipoyl)lysine + NAD(+) → protein N(6)-(lipoyl)lysine + NADH.
General function:
Involved in oxoglutarate dehydrogenase (succinyl-transferring) activity
Specific function:
The 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). It contains multiple copies of three enzymatic components:2- oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3)
Gene Name:
KGD1
Uniprot ID:
P20967
