| 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.

| resorcinol | M-dihydroxybenzene; 1,3-benzenediol;used internally for the relief of nausea, asthma, whooping cough, and diarrhoea, but chiefly as an external antiseptic in psoriasis, eczema, seborrhoea, and ringworm; pyrocatechol and hydroquinone are isomers of resorcinol. Synonym: resorcin. Resorcinol monoacetate, used externally in the treatment of acne, sycosis, and seborrhoea. (05 Mar 2000) |

| resorcinol test | A test for fructosuria; fresh urine treated with resorcinol in acid gives a red precipitate in the presence of fructose; the precipitate should form a red solution in ethanol. Synonym: Selivanoff's test. (05 Mar 2000) |
| phthalic | <chemistry> Pertaining to, or designating, a dibasic acid obtained by the oxidation of naphthalene and allied substances. <chemistry> Phthalic acid, a white crystalline substance, C6H4.(CO2H)2, analogous to benzoic acid, and employed in the brilliant dyestuffs called the phthaleins. Origin: Naphthalene + -ic. Source: Websters Dictionary (01 Mar 1998) |
| phthalic acid | O-Benzenedicarboxylic acid;c6H4(COOH)2. (05 Mar 2000) |
| phthalic acids | A group of compounds that has the general structure of a dicarboxylic acid-substituted benzene ring. The ortho-isomer is used in dye manufacture. (12 Dec 1998) |
| phthalic anhydrides | Phthalic acid anhydrides. Can be substituted on any carbon atom. Used extensively in industry and as a reagent in the acylation of amino- and hydroxyl groups. (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) |
| 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) |
| silicic anhydride | Fine particulate dust from quartz rock that is known to cause a progressive lung injury over long-term. See: pneumoconiosis. (27 Sep 1997) |
