| omega-oxidation | Oxidation at the carbon atom farthest removed (ω-carbon) from the carboxyl group (carbon 1); thus, in this pathway, a dicarboxylic acid is formed; an important pathway in the degradation of prostaglandins. (05 Mar 2000) |
|---|---|
| omega-oxidation theory | That the oxidation of fatty acids commences at the CH3 group, i.e., the terminal or omega-group; beta-oxidation then proceeds at both ends of the fatty acid chain. (05 Mar 2000) |
| oxidation | <biochemistry> The process whereby fatty acids are degraded in steps, losing 2 carbons as (acetyl) CoA. Involves CoA ester formation, desaturation, hydroxylation and oxidation before each cleavage. (18 Nov 1997) |
| oxidation-fermentation test | <investigation> A test to to determine whether a given bacterial strain has an oxidative or fermentativetype of metabolism by seeing what it doesto a carbohydrate substrate. (09 Oct 1997) |
| oxidation number | The number of electrons necessary to restore an atom in a combined state to its elemental form. (09 Oct 1997) |
| oxidation pond | A pond that contains partially treated wastewater which is then left to allow the growth of algae and bacteria which decompose therest of the waste. (09 Oct 1997) |
| terminal oxidation | <biochemistry> The last oxidation step in a catabolic pathway. Synonym: terminal oxidation. (05 Mar 2000) |
| end oxidation | <biochemistry> The last oxidation step in a catabolic pathway. Synonym: terminal oxidation. (05 Mar 2000) |
| fatty acid oxidation cycle | A series of reactions involving acyl-coenzyme A compounds, whereby these undergo beta oxidation and thioclastic cleavage, with the formation of acetyl-coenzyme A; the major pathway of fatty acid catabolism in living tissue. (05 Mar 2000) |
| acetyl reduction assay | <investigation> A technique for measuring the nitrogen fixation activity in photosynthetic organisms. It uses a flame ionisation detector and a gas chromatography apparatus to determine the reduction of acetylene to ethylene by the enzyme nitrogenase. (06 May 1997) |
| reduction | <orthopaedics, surgery> The correction of a fracture, dislocation or hernia. (18 Nov 1997) |
| reduction deformity | Congenital absence or attenuation of one or more body parts; usually of the limbs or limb components. (05 Mar 2000) |
| reduction division | The first cell division in meiosis, the process by which germ cells are formed. A unique event in which the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes). Also called first meiotic division or first meiosis. (12 Dec 1998) |
| reduction en masse | Reduction of hernial sac and contents, so that intestinal obstruction is still present. (05 Mar 2000) |
| reduction mammaplasty | Plastic surgery of the breast to reduce its size and (frequently) to improve its shape and position. (05 Mar 2000) |
