| phosphoroclastic cleavage | <biochemistry> This reaction is an analogue to hydrolysis, except here a molecule is cleaved with phosphate as the attacking group. (09 Oct 1997) |

| phosphoroclastic reaction | Cleavage of C-C bonds that involves phosphate transfer but not, as in phosphorolysis, directly to one of the products; e.g., the decomposition of pyruvate to acetate + CO2, in which Pi is added to ADP to form ATP. (05 Mar 2000) |
| phosphorolysis | <biochemistry> This reaction is an analogue to hydrolysis, except here a molecule is cleaved with phosphate as the attacking group. (09 Oct 1997) |
| phosphoroscope | <instrument, physics> An apparatus for observing the phosphorescence produced in different bodies by the action of light, and for measuring its duration. Origin: Phosphorus + -scope. Source: Websters Dictionary (01 Mar 1998) |
| phosphorous | <chemistry> Of or pertaining to phosphorus; resembling or containing phosphorus; specifically, designating those compounds in which phosphorus has a lower valence as contrasted with phosphoric compounds; as, phosphorous acid, H3PO3. Origin: Cf. F. Phosphoreux. Source: Websters Dictionary (01 Mar 1998) |
| phosphorous acid | H3PO3;its salts are phosphites. (05 Mar 2000) |
| phosphorous acids | Inorganic or organic derivatives of phosphorous acid (p(oh)3). Inorganic salts are known as phosphites. The tautomeric form of this compound (hpo(oh)2) = phosphonic acids. (12 Dec 1998) |
