In enzymology, a 3alpha,7alpha,12alpha-trihydroxy-5beta-cholestanoyl-CoA 24-hydroxylase (EC 1.17.99.3) is an enzyme that catalyzes the chemical reaction

(25R)-3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-26-oyl-CoA + H2O + acceptor (24R,25R)-3alpha,7alpha,12alpha,24-tetrahydroxy-5beta-cholestan-26- oyl-CoA + reduced acceptor

The 3 substrates of this enzyme are (25R)-3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-26-oyl-CoA, H2O, and acceptor, whereas its two products are (24R,25R)-3alpha,7alpha,12alpha,24-tetrahydroxy-5beta-cholestan-26-oyl-CoA, and reduced acceptor.

This enzyme belongs to the family of oxidoreductases, specifically those acting on CH or CH2 groups with other acceptors. The systematic name of this enzyme class is (25R)-3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-26-oyl-CoA:ac ceptor 24-oxidoreductase (24R-hydroxylating). Other names in common use include trihydroxycoprostanoyl-CoA oxidase, THC-CoA oxidase, THCA-CoA oxidase, 3alpha,7alpha,12alpha-trihydroxy-5beta-cholestanoyl-CoA oxidase, 3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-26-oate 24-hydroxylase. This enzyme participates in the ppar signaling pathway.

Alkylglycerol monooxygenase (AGMO) is an enzyme that catalyzes the hydroxylation of alkylglycerols, a specific subclass of ether lipids. This enzyme was first described in 1964 as a pteridine-dependent ether lipid cleaving enzyme. In 2010 finally, the gene coding for alkylglycerol monooxygenase was discovered as transmembrane protein 195 (TMEM195) on chromosome 7. In analogy to the enzymes phenylalanine hydroxylase, tyrosine hydroxylase, tryptophan hydroxylase and nitric oxide synthase, alkylglycerol monooxygenase critically depends on the cofactor tetrahydrobiopterin and iron.

2-acyl-sn-glycero-3-phosphocholines are a class of phospholipids that are intermediates in the metabolism of lipids. Because they result from the hydrolysis of an acyl group from the sn-1 position of phosphatidylcholine, they are also called 1-lysophosphatidylcholine. The synthesis of phosphatidylcholines with specific fatty acids occurs through the synthesis of 1-lysoPC. The formation of various other lipids generates 1-lysoPC as a by-product.
