Metabolite Identification
Common NameArachidic acid
DescriptionArachidic acid, also known as eicosanoic acid or eicosanoate, 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. Arachidic acid is a potentially toxic compound.

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.
Gene Name:
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:
85210.19
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.
Gene Name:
PLA2G1B
Uniprot ID:
P04054
Molecular weight:
16359.535
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 powerful potency for releasing arachidonic acid from cell membrane phospholipids. Prefers phosphatidylethanolamine and phosphatidylcholine liposomes to those of phosphatidylserine.
Gene Name:
PLA2G10
Uniprot ID:
O15496
Molecular weight:
18153.04
General function:
Involved in sugar binding
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
Gene Name:
