| palm oil | An oil obtained from the seeds of Elaeis guineensis (family Palmae); used in the manufacture of soap, liniments, and ointments; also in foods. (05 Mar 2000) |

| 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) |
| palm | 1. <anatomy> The inner and somewhat concave part of the hand between the bases of the fingers and the wrist. "Clench'd her fingers till they bit the palm." (Tennyson) 2. A lineal measure equal either to the breadth of the hand or to its length from the wrist to the ends of the fingers; a hand; used in measuring a horse's height. In Greece, the palm was reckoned at three inches. The Romans adopted two measures of this name, the lesser palm of 2.91 inches, and the greater palm of 8.73 inches. At the present day, this measure varies in the most arbitrary manner, being different in each country, and occasionally varying in the same. 3. A metallic disk, attached to a strap, and worn the palm of the hand, used to push the needle through the canvas, in sewing sails, etc. 4. <zoology> The broad flattened part of an antler, as of a full-grown fallow deer; so called as resembling the palm of the hand with its protruding fingers. 5. The flat inner face of an anchor fluke. Origin: OE. Paume, F. Paume, L. Palma, Gr, akin to Skr. Pani hand, and E. Fumble. See Fumble, Feel, and cf. 2d Palm. 1. <botany> Any endogenous tree of the order Palmae or Palmaceae; a palm tree. Palms are perennial woody plants, often of majestic size. The trunk is usually erect and rarely branched, and has a roughened exterior composed of the persistent bases of the leaf stalks. The leaves are borne in a terminal crown, and are supported on stout, sheathing, often prickly, petioles. They are usually of great size, and are either pinnately or palmately many-cleft. There are about one thousand species known, nearly all of them growing in tropical or semitropical regions. The wood, petioles, leaves, sap, and fruit of many species are invaluable in the arts and in domestic economy. Among the best known are the date palm, the cocoa palm, the fan palm, the oil palm, the wax palm, the palmyra, and the various kinds called cabbage palm and palmetto. 2. A branch or leaf of the palm, anciently borne or worn as a symbol of victory or rejoicing. "A great multitude . . . Stood before the throne, and before the Lamb, clothed with white robes, and palme in their hands." (Rev. Vii. 9) 3. Hence: Any symbol or token of superiority, success, or triumph; also, victory; triumph; supremacy. "The palm of martyrdom." "So get the start of the majestic world And bear the palm alone. <botany>" (Shak) Molucca palm The larva of a palm weevil. A centipede. Origin: AS. Palm, L. Palma; so named fr. The leaf resembling a hand. See lst Palm, and cf. Pam. Source: Websters Dictionary (01 Mar 1998) |
