Metabolite Identification
Common NameArachidic acid
DescriptionArachidic acid, also known as icosanoic acid, is a saturated fatty acid with a 20-carbon chain. It is a minor constituent of butter, perilla oil, peanut oil, corn oil, and cocoa butter. It also constitutes 7.08% of the fats from the fruit of the durian species Durio graveolens. The salts and esters of arachidic acid are known as arachidates. Its name derives from the Latin arachis that means peanut. It can be formed by the hydrogenation of arachidonic acid. The reduction of arachidic acid yields arachidyl alcohol. Arachidic acid is used for the production of detergents, photographic materials and lubricants. Arachidic acid belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Arachidic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral.

Enzymes

General function:
Involved in transferase activity
Specific function:
Fatty acid synthetase catalyzes the formation of long-chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH. This multifunctional protein has 7 catalytic activities and an acyl carrier protein.
Gene Name:
FASN
Uniprot ID:
P49327
Molecular weight:
273424.06
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. This isozyme hydrolyzes more efficiently L-alpha-1-palmitoyl-2-oleoyl phosphatidylcholine than L-alpha-1-palmitoyl-2-arachidonyl phosphatidylcholine, L-alpha-1-palmitoyl-2-arachidonyl phosphatidylethanolamine, or L-alpha-1-stearoyl-2-arachidonyl phosphatidylinositol. May be involved in the production of lung surfactant, the remodeling or regulation of cardiac muscle.

PLA2G5
Uniprot ID:
P39877
Molecular weight:
15674.065
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Hydrolyzes phosphatidylglycerol versus phosphatidylcholine with a 15-fold preference.
Gene Name:
PLA2G2F
Uniprot ID:
Q9BZM2
Molecular weight:
23256.29
General function:
Involved in metabolic process
Specific function:
Selectively hydrolyzes arachidonyl phospholipids in the sn-2 position releasing arachidonic acid. Together with its lysophospholipid activity, it is implicated in the initiation of the inflammatory response.
Gene Name:
PLA2G4A
Uniprot ID:
P47712
Molecular weight:

Specific function:
Has lysophospholipase activity.
Gene Name:
LGALS13
Uniprot ID:
Q9UHV8
Molecular weight:
16118.44
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Has a preference for arachidonic-containing phospholipids.
Gene Name:
PLA2G2E
Uniprot ID:
Q9NZK7
Molecular weight:
15988.525
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Does not exhibit detectable activity toward sn-2-arachidonoyl- or linoleoyl-phosphatidylcholine or -phosphatidylethanolamine.
Gene Name:
PLA2G12A
Uniprot ID:
Q9BZM1
Molecular weight:
21066.99
General function:
Involved in metabolic process
Specific function:
Catalyzes the release of fatty acids from phospholipids. It has been implicated in normal phospholipid remodeling, nitric oxide-induced or vasopressin-induced arachidonic acid release and in leukotriene and prostaglandin production. May participate in fas mediated apoptosis and in regulating transmembrane ion flux in glucose-stimulated B-cells. Has a role in cardiolipin (CL) deacylation. Required for both speed and directionality of monocyte MCP1/CCL2-induced chemotaxis through regulation of F-actin polymerization at the pseudopods. Isoform ankyrin-iPLA2-1 and isoform ankyrin-iPLA2-2, which lack the catalytic domain, are probably involved in the negative regulation of iPLA2 activity.
Gene Name:
PLA2G6
Uniprot ID:
O60733
Molecular weight:
84092.635

Transporters

General function:
Lipid transport and metabolism
Specific function:
Involved in translocation of long-chain fatty acids (LFCA) across the plasma membrane. The LFCA import appears to be hormone-regulated in a tissue-specific manner. In adipocytes, but not myocytes, insulin induces a rapid translocation of FATP1 from intracellular compartments to the plasma membrane, paralleled by increased LFCA uptake. May act directly as a bona fide transporter, or alternatively, in a cytoplasmic or membrane- associated multimeric protein complex to trap and draw fatty acids towards accumulation. Plays a pivotal role in regulating available LFCA substrates from exogenous sources in tissues undergoing high levels of beta-oxidation or triglyceride synthesis. May be involved in regulation of cholesterol metabolism. Has acyl-CoA ligase activity for long-chain and very-long-chain fatty acids
