| silicic | <chemistry> Pertaining to, derived from, or resembling, silica; specifically, designating compounds of silicon; as, silicic acid. <chemistry> Silicic acid, an amorphous gelatinous substance, Si(HO)4, very unstable and easily dried to silica, but forming many stable salts. Synonym: orthosilicic, or normal silicic, acid. Origin: L. Silex, silicis, a flint: cf. F. Silicique. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| silicic acid | <chemical> Silicic acid. Hydrated silicon dioxide that occurs in nature. It is insoluble in water or acids except hydrofluoric acid. Chemical name: Silicic acid (12 Dec 1998) |
| acetic anhydride | <chemistry> Anhydrides of acetic acid. Used extensively as acetylation, oxidation and dehydrating agents and in the modification of proteins and enzymes. (12 Dec 1998) |
| acetic phosphoric anhydride | CH3CO-OPO32-;a "high energy" phosphate that acts as an acetate donor in the metabolism of various bacteria. Synonym: acetic phosphoric anhydride. (05 Mar 2000) |
| acid anhydride hydrolases | <enzyme> A group of enzymes that catalyze the hydrolysis of diphosphate bonds in compounds such as nucleoside di- and tri-phosphates, and sulfonyl-containing anhydrides such as adenylylsulfate. (enzyme nomenclature, 1992). Registry number: EC 3.6 (12 Dec 1998) |
| acidic anhydride | <chemistry> A substance (such as the oxide of a nonmetallic element) that will react with water to form an acid. (09 Oct 1997) |
| anhydride | <chemistry> A compound that becomes an acid in the presence of water or becomes a base when water is removed. (12 Nov 1997) |
| basic anhydride | <chemical> A chemical (usually the oxide of a metal) which forms a base when it is mixed with water. (09 Oct 1997) |
| carbonic anhydride | <biochemistry, physiology> A metabolic byproduct of carbohydrate metabolism. Carbon Dioxide collects in the tissues, is cleared by the blood (via the veins) and removed from the body via the lungs when we exhale air. Abbreviation: CO2 (13 Nov 1997) |
| resorcinol phthalic anhydride | <chemical> Fluorophore commonly used in microscopy. Fluorescein di acetate can be used as a vital stain or can be conjugated to proteins (particularly antibodies) using isothiocyanate. Excitation is at 365nm and the emitted light is green yellow (450-490nm). The emission spectrum is pH sensitive and fluorescein can therefore be used to measure pH in intracellular compartments. (18 Nov 1997) |
| coumaric anhydride | <drug> O hydroxycinnamic acid. Pleasant smelling compound found in many plants and released on wilting (probably a major component of the smell of fresh hay). Has anticoagulant activity by competing with Vitamin K. (18 Nov 1997) |
| trimethylglycocoll anhydride | <chemical> A derivative of glycine characterised by high water solubility. Can function as an osmotic agent in plant tissues. See: biogenic amines. (18 Nov 1997) |
