| MCFA | Medium-chain fatty acids |
| MUFA | Monounsaturated fatty acids |
| monounsaturated fatty acids | A fatty acid chain with at least two empty spaces that could be hydrogenated (have a hydrogen atom added). Saturated (hydrogenated) fatty acids are a greater health risk for the development of atherosclerotic vascular disease. (27 Sep 1997) |
|---|---|
| saturated fatty acids | In eukaryotic membranes refers to stearic, palmitic and myristic acids, that are linear aliphatic chains with no double bonds. Prokaryotes have numerous branched chain saturated fatty acids. (18 Nov 1997) |
| omega 3 fatty acids | A class of fatty acids that have a double bond three carbons from the methyl moiety; reportedly, they play a role in lowering cholesterol and LDL levels. Synonym: omega-3 fatty acids. (05 Mar 2000) |
| fatty acids | Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (fatty acids, unsaturated). (12 Dec 1998) |
| fatty acids, essential | Fatty acids that cannot be synthesised by the human body and must be obtained from dietary sources, e.g., linoleic acids and linolenic acids. (12 Dec 1998) |
| fatty acids, monounsaturated | Fatty acids which are unsaturated in only one position. (12 Dec 1998) |
| fatty acids, nonesterified | The fraction of plasma fatty acids that are not in the form of glycerol esters. They are also called free fatty acids, but this is a misnomer because they are transported complexed with albumin. (12 Dec 1998) |
| fatty acids, omega-3 | A group of fatty acids, often of marine origin, which have the first unsaturated bond in the third position from the omega carbon. These fatty acids are believed to reduce serum triglycerides, prevent insulin resistance, improve lipid profile, prolong bleeding times, reduce platelet counts, and decrease platelet adhesiveness. (12 Dec 1998) |
| fatty acids, unsaturated | Fatty acids containing one (monounsaturated) or multiple (polyunsaturated) double bonds. They predominate in most plant-derived fats. The number and position of each double bond can be specified, as in the systematic names, or the position of the double bond closest to the methyl group (omega) terminus can be specified to denote functional subdivisions of the overall group, e.g., omega-3 fatty acids. The numbers and positions of the double bonds have been linked to effects on plasma lipid, triglyceride, and cholesterol levels. (12 Dec 1998) |
| fatty acids, volatile | Short-chain fatty acids of up to six carbon atoms in length. They are the major end products of microbial fermentation in the ruminant digestive tract and have also been implicated in the causation of neurological diseases in humans. (12 Dec 1998) |
| all-trans-retinal | The orange retinaldehyde resulting from the action of light on the rhodopsin of the retina, which converts the 11-cis-retinal component of the rhodopsin to all-trans-retinal plus opsin. Synonym: trans-retinal, visual yellow. (05 Mar 2000) |
| peptidyl prolyl cis trans isomerase | See: PPIase and immunophilin. (18 Nov 1997) |
| cis-9,trans-11-octadecadienoate reductase | <enzyme> Uses NADH and alpha-tocopherol quinol; forms trans-11-octadecenoate Registry number: EC 1.3.1.- Synonym: 9,11-ocdd reductase (26 Jun 1999) |
| cis-trans-isomerases | <enzyme> Enzymes that catalyze the rearrangement of geometry about double bonds. Registry number: EC 5.2 (12 Dec 1998) |
| cis trans test | <molecular biology> The complementation test with two or more interacting genes placed in cis and in trans relationships to each other. A double mutant genome is used in the cis test made from the two single mutant genomes used in the trans test by recombination. If the wild type phenotype is restored by both cis and trans arrangements it is concluded that the two mutations are in different genes and hence that the phenotype is determined by more than one gene. If the trans test is negative and the cis positive this means that the two mutations are in the same gene. If both tests are negative then at least one of the mutations must be dominant. Thus the double test provides a means of fine mapping of genes. A lab test which is used to determine whether two mutations of different genes which affect the same phenotype are on the same functional unit (indicating a cis configuration of the mutated genes) or on different functional units (indicating a trans configuration of the mutated genes). (A functional unit can be a chromosome.) The test is done by mating an individual that has one of the mutations to an individual that has the other one, and observing whether their offspring have the mutant phenotype. If the offspring do not have the mutant phenotype, then the genes are known to be trans, because the offspring have normal copies of each mutant gene on the different functional units which are able to genetically complement each other. If the offspring do have the mutant phenotype, then the genes are known to be cis, because the offspring will always inherit at least one of the mutant genes on the one functional unit, resulting in the mutant phenotype.
