| 3-methylcholanthrene | A highly carcinogenic hydrocarbon that can be formed chemically from deoxycholic or cholic acids, or from cholesterol; the choice between 3-or 20-for the methyl group depends upon whether hydrocarbon (inner) or steroid (outer) numbering is chosen; in the latter case, the formal relationship to the cholic acids and cholesterol is clear.

| 3-methylglutaconic aciduria | Elevated levels of 3-methylglutaconic acid in the urine. An inherited disorder whose mild form is a result of a deficiency of 3-methylglutaconyl-CoA hydratase, leading to delayed speech development. (05 Mar 2000) |
| 3-methylglutaconyl-CoA hydratase | <enzyme> An enzyme that catalyses the reaction of trans-3-methylglutaconyl-CoA and water to form 3-hydroxy-3-methylglutaconyl-CoA; this enzyme participates in the pathway for l-leucine degradation; a deficiency of this enzyme will result in 3-methylglutaconic aciduria.

| 3-oxoacid-CoA transferase | <enzyme> An enzyme catalyzing the reversible conversion of acetoacetyl-CoA and succinate into succinyl-CoA and acetoacetate; malonyl-CoA can substitute for succinyl-CoA and a few other 3-oxo acids for the acetoacetate; an important step in order for the ketone bodies to serve as a fuel for extrahepatic tissues. Synonym: 3-ketoacid-CoA transferase, acetoacetyl-succinic thiophorase. (05 Mar 2000) |
| 3-oxoacyl-(acyl-carrier-protein) synthase | <enzyme> An enzyme of long-chain fatty acid synthesis, that adds a two-carbon unit from malonyl-(acyl carrier protein) to another molecule of fatty acyl-(acyl carrier protein), giving a beta-ketoacyl-(acyl carrier protein) with the release of carbon dioxide. Chemical name: Acyl-(acyl carrier protein):malonyl-(acyl-carrier-protein) C-acyltransferase (decarboxylating) Registry number: EC 2.3.1.41 (12 Dec 1998) |
| 3-oxoacyl-ACP reductase | A part of the fatty acid synthase complex; an enzyme reversibly reacting 3-oxoacyl-ACP with NADPH to form d-3-hydroxyacyl-ACP and NADP+. Synonym: beta-ketoacyl-ACP reductase. (05 Mar 2000) |
| 3-oxoacyl-ACP synthase | <enzyme> An enzyme condensing malonyl-ACP and acyl-cys-protein to 3-oxoacyl-ACP + cys-protein + CO2, and similar reactions, as steps in fatty acid synthesis; cys-protein is also a part of the fatty acid synthase complex. Synonym: acyl-malonyl-ACP synthase, beta-ketoacyl-ACP synthase. (05 Mar 2000) |
| 3-oxobutyryl-CoA reductase | <enzyme> Nadh-dependent, (s)-specific enzyme from clostridium tyrobutyricum; n-terminal amino acid sequence given in first source Registry number: EC 1.1.1.- (26 Jun 1999) |

| 3-methylcholanthrene |
a highly carcinogenic polycyclic aromatic hydrocarbon synthesized by pyrolytic degradation of cholic acid, deoxycholic acid, or cholesterol. It is a procarcinogen that requires metabolic activation to exert a mutagenic effect and is widely used in laboratory studies of chemical carcinogenesis. Abbreviated MCA.
