Identification
Name:Palmitic acid
DescriptionPalmitic acid, or hexadecanoic acid is a saturated fatty acids. Palmitic acid is the first fatty acid produced during lipogenesis (fatty acid synthesis) and from which longer fatty acids can be produced. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC) which is responsible for converting acetyl-CoA to malonyl-CoA which is used to add to the growing acyl chain, thus preventing further palmitate generation.

2-lysophosphatidylcholine + H(2)O = glycerophosphocholine + a carboxylate.
General function:
Involved in [acyl-carrier-protein] phosphodiesterase activity
Specific function:
Converts holo-ACP to apo-ACP by hydrolytic cleavage of the phosphopantetheine prosthetic group from ACP
Gene Name:
acpH
Uniprot ID:
P21515
Molecular weight:

Reactions
Holo-[acyl-carrier-protein] + H(2)O = 4'-phosphopantetheine + apo-[acyl-carrier-protein].
General function:
Involved in transferase activity, transferring acyl groups
Specific function:
Plays a role in lysophospholipid acylation. Transfers fatty acids to the 1-position via an enzyme-bound acyl-ACP intermediate in the presence of ATP and magnesium. Its physiological function is to regenerate phosphatidylethanolamine from 2-acyl-glycero-3-phosphoethanolamine (2-acyl-GPE) formed by transacylation reactions or degradation by phospholipase A1

Reactions
Acyl-[acyl-carrier-protein] + O-(2-acyl-sn-glycero-3-phospho)ethanolamine = [acyl-carrier-protein] + O-(1-beta-acyl-2-acyl-sn-glycero-3-phospho)ethanolamine.
ATP + an acid + [acyl-carrier-protein] = AMP + diphosphate + acyl-[acyl-carrier-protein].
General function:
Involved in catalytic activity
Specific function:
Catalyzes the esterification, concomitant with transport, of exogenous long-chain fatty acids into metabolically active CoA thioesters for subsequent degradation or incorporation into phospholipids
