| isopropyl alcohol | Used as a component of various cosmetics and astringents, when taken internally can be toxic (27 Sep 1997) |
|---|---|
| isopropyl myristate | <chemical> A pharmaceutic aid used in topical medicinal preparations to promote absorption through the skin. (05 Mar 2000) |
| isopropyl thiogalactoside | <chemical> 1-methylethyl 1-thio-beta-d-galactopyranoside. An artificial galactoside capable of inducing beta-galactosidase in Escherichia coli without being split, as are the natural substrates such as lactose. Chemical name: beta-D-Galactopyranoside, 1-methylethyl 1-thio- (05 Mar 2000) |
| lecithin | <protein> Phospholipids of egg yolk (usually hen's eggs). A mixture of phosphatidylcholine and phosphatidylethanolamine, but usually refers to phosphatidylcholine. (18 Nov 1997) |
| lecithin acyltransferase | <enzyme> An enzyme that reversibly transfers an acyl residue from a lecithin to cholesterol, forming a 1-acylglycerophosphocholine (a lysolecithin) and a cholesterol ester; a deficiency of this enzyme leads to an accumulation of unesterified cholesterol in plasma resulting in anaemia, proteinuria, renal failure, and corneal opacities; LCAT is also low in individuals with fish-eye disease. Synonym: lecithin acyltransferase. Acronym: LCAT (05 Mar 2000) |
| lecithin acyltransferase deficiency | A disease characterised by deficiency or low levels of plasma lecithin cholesterol acyl transferase. Clinical manifestations include corneal opacity, anaemia, and proteinuria. (12 Dec 1998) |
| lecithin-cholesterol acyltransferase | <enzyme> An enzyme that reversibly transfers an acyl residue from a lecithin to cholesterol, forming a 1-acylglycerophosphocholine (a lysolecithin) and a cholesterol ester; a deficiency of this enzyme leads to an accumulation of unesterified cholesterol in plasma resulting in anaemia, proteinuria, renal failure, and corneal opacities; LCAT is also low in individuals with fish-eye disease. Synonym: lecithin acyltransferase. Acronym: LCAT (05 Mar 2000) |
| lecithin-cholesterol transferase | A plasma enzyme that catalyses the uptake of cholesterol esters by intermediate-density lipoproteins formed by high density lipoproteins. (05 Mar 2000) |
| lecithin-retinol acyltransferase | <enzyme> Transfers 1-acyl moiety from lecithin to retinol-cellular retinol-binding protein, type II, to produce retinyl esters; does not use CoA Registry number: EC 2.3.1.- (26 Jun 1999) |
| lecithin/sphingomyelin ratio | A ratio used to determine foetal pulmonary maturity, found by testing the amniotic fluid; when the lungs are mature, lecithin exceeds sphingomyelin by 2 to 1. (05 Mar 2000) |
| lysolecithin-lecithin acyltransferase | <enzyme> An enzyme that catalyses the reversible reaction of lysolecithin and another phospholipid (e.g., phosphatidylethanolamine) to form lecithin and lysophosphatidylethanolamine; a major route in the restructuring of lecithin. (05 Mar 2000) |
| acid-base balance | The normal balance between acid and base in the blood plasma, expressed in the hydrogen ion concentration or pH, resulting from the relative amounts of acidic and basic materials ingested and produced by body metabolism, compared to the relative amounts of acidic and basic materials excreted from the body and consumed by body metabolism; the normal state of acid-base balance is not one of neutrality, with equal concentrations of hydrogen and hydroxyl ions, but a more alkaline state with a certain excess of hydroxyl ions. Synonym: acid-base equilibrium. (05 Mar 2000) |
| acid-base equilibrium | A condition in which the net rate of acid or alkali production by the body is balanced by the net rate of acid or alkali excretion from the body, resulting in a stable concentration of hydrogen ions in the body fluids. (12 Dec 1998) |
| acid-base imbalance | Disturbances in the acid-base equilibrium of the body. (12 Dec 1998) |
| acrylic resin base | A form made of acrylic resin molded to conform to the tissues of the alveolar process and used to support the teeth of a prosthesis. (05 Mar 2000) |
