DescriptionTetracosanoic acid, also known as N-tetracosanoate or lignoceric acid, belongs to the class of organic compounds known as very long-chain fatty acids. These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Tetracosanoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Tetracosanoic acid is a potentially toxic compound.

General function:
Involved in fatty acid elongase activity
Specific function:
Involved in synthesis of 1,3-beta-glucan. Could be a subunit of 1,3-beta-glucan synthase. Could be also a component of the membrane bound fatty acid elongation systems that produce the 26-carbon very long chain fatty acids that are precursors for ceramide and sphingolipids. Appears to be involved in the elongation of fatty acids up to 24 carbons. Appears to have the highest affinity for substrates with chain length less than 22 carbons
Gene Name:
Uniprot ID:
Molecular weight:
Acyl-CoA + malonyl-CoA → 3-oxoacyl-CoA + CoA + CO(2).
General function:
Involved in acyl-CoA thioesterase activity
Specific function:
Acyl-CoA thioesterases are a group of enzymes that catalyze the hydrolysis of acyl-CoAs to the free fatty acid and coenzyme A (CoASH), providing the potential to regulate intracellular levels of acyl-CoAs, free fatty acids and CoASH
Gene Name:
Uniprot ID:
Molecular weight:
Palmitoyl-CoA + H(2)O → CoA + palmitate.


General function:
Involved in catalytic activity
Specific function:
May be involved in long-chain fatty acids uptake, and thus may play a pivotal role in regulating their accessibility prior to metabolic utilization. May play an important role in uptake of these hydrophobic compounds under conditions where fatty acid synthesis is compromised
