| neutral lipid storage disease | <syndrome> Congenital ichthyosis, leukocyte vacuoles, and variable involvement of other organ systems. Synonym: neutral lipid storage disease. (05 Mar 2000) |
| disease, lipid storage | A series of disorders due to inborn errors in lipid metabolism resulting in the abnormal accumulation of lipids in the wrong places (Examples include Gaucher, Fabry and Niemann-Pick diseases and metachromatic leukodystrophy). (12 Dec 1998) |
| inositol lipid | A membrane-anchored phospholipid that transduces hormonal signals by stimulating the release of any of several chemical messengers. (09 Oct 1997) |
| isotropic lipid | A lipid occurring in the form of singly refractive droplets. (05 Mar 2000) |
| lipid | <chemical> Any of a heterogeneous group of flats and fatlike substances characterised by being water insoluble and being extractable by nonpolar (or fat) solvents such as alcohol, ether, chloroform, benzene, etc. All contain as a major constituent aliphatic hydrocarbons. The lipids, which are easily stored in the body, serve as a source of fuel, are an important constituent of cell structure and serve other biological functions. Lipids may be considered to include fatty acids, neutral fats, waxes and steroids. Compound lipids comprise the glycolipids, lipoproteins and phospholipids. (18 Nov 1997) |
| lipid A | The lipid associated with polysaccharide in the lipopolysaccharide of gram-negative bacterial cell walls. (18 Nov 1997) |
| lipid A 4'-phosphatase | <enzyme> Involved in lipid a biosynthesis in rhizobium leguminosarum Registry number: EC 3.1.3.- Synonym: 2-keto-3-deoxyoctulosonate-activated 4'-phosphatase, kdo-activated lipid a 4'-phosphatase (26 Jun 1999) |
| lipid A disaccharide synthase | <enzyme> Udp-diacyl-n-acetylglucosamine plus 2,3-diacyl-n-acetylglucosamine-1-phosphate yields 2',3'-diacyl-glcn-(beta 1-6)-2,3-diacyl-glcn-1-p plus udp Registry number: EC 2.4.1.182 Synonym: 2,3-diacyl-n-acetylglucosamine diacyl-n-acetylglucosaminyltransferse, lipid a synthase (26 Jun 1999) |
| lipid bilayer | <biochemistry> A lamellar organisation of phospholipids that are packed as a bilayer with hydrophobic acyl tails inwardly directed and polar head groups on the outside surfaces. It is this bilayer that forms the basis of membranes in cells, though in most cellular membranes a very substantial proportion of the area may be occupied by integral proteins. The triple layered appearance of membranes seen in electron microscopy is thought to arise because the osmium tetroxide binds to the polar regions leaving a central, unstained, hydrophobic region. (31 Dec 1997) |
| lipid bilayers | Layers of lipid molecules which are two molecules thick. Bilayer systems are frequently studied as models of biological membranes. (12 Dec 1998) |
| lipid granulomatosis | <dermatology, pathology> An accumulation of an excess of lipids in the body due to disturbance of lipid metabolism and marked by the formation of foam cells in skin lesions. (16 Dec 1997) |
