Metabolite Identification

Common Name

Dihomo-gamma-linolenic acid

Description

8,11,14-Eicosatrienoic acid is a 20-carbon-chain omega-6 fatty acid, unsaturated at positions 8, 11, and 14. It differs from arachidonic acid (5,8,11,14-eicosatetraenoic acid) only at position 5. 8,11,14-Eicosatrienoic acid is also known as Dihomo-gamma-linolenic acid (DGLA). In physiological literature, it is given the name 20:3(n-6). DGLA is the elongation product of the 18 carbon gamma-linolenic acid (GLA). DGLA can be converted into prostaglandin E1 (PGE1). PGE1 inhibits platelet aggregation and also exerts a vasodilatory effect. DGLA competes with arachadonic acid for COX and lipoxygenase, inhibiting the production of arachadonic acid's eicosanoids.

Enzymes

Enzyme Details

1. Bile acid-CoA:amino acid N-acyltransferase

General function:: Involved in thiolester hydrolase activity
Specific function:: Involved in bile acid metabolism. In liver hepatocytes catalyzes the second step in the conjugation of C24 bile acids (choloneates) to glycine and taurine before excretion into bile canaliculi. The major components of bile are cholic acid and chenodeoxycholic acid. In a first step the bile acids are converted to an acyl-CoA thioester, either in peroxisomes (primary bile acids deriving from the cholesterol pathway), or cytoplasmic at the endoplasmic reticulum (secondary bile acids). May catalyze the conjugation of primary or secondary bile acids, or both. The conjugation increases the detergent properties of bile acids in the intestine, which facilitates lipid and fat-soluble vitamin absorption. In turn, bile acids are deconjugated by bacteria in the intestine and are recycled back to the liver for reconjugation (secondary bile acids). May also act as an acyl-CoA thioesterase that regulates intracellular levels of free fatty acids. In vitro, catalyzes the hydrolysis of long- and very long-chain saturated acyl-CoAs to the free fatty acid and coenzyme A (CoASH), and conjugates glycine to these acyl-CoAs.

2. Cytosolic acyl coenzyme A thioester hydrolase

General function:: Lipid transport and metabolism
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. May play an important physiological function in brain. May play a regulatory role by modulating the cellular levels of fatty acyl-CoA ligands for certain transcription factors as well as the substrates for fatty acid metabolizing enzymes, contributing to lipid homeostasis. Has broad specificity, active towards fatty acyl-CoAs with chain-lengths of C8-C18. Has a maximal activity toward palmitoyl-CoA.
