| 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) |

| phosphorus | Origin: L, the morning star, Gr, lit, light bringer; light + to bring. 1. The morning star; Phosphor. 2. <chemistry> A poisonous nonmetallic element of the nitrogen group, obtained as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell. It is very active chemically, must be preserved under water, and unites with oxygen even at ordinary temperatures, giving a faint glow, whence its name. It always occurs compined, usually in phosphates, as in the mineral apatite, in bones, etc. It is used in the composition on the tips of friction matches, and for many other purposes. The molecule contains four atoms. Symbol P. Atomic weight 31.0. 3. <chemistry> Hence, any substance which shines in the dark like phosphorus, as certain phosphorescent bodies. <medicine> Bologna phosphorus, phosphorescent substances which shine in the dark after exposure to the sunlight or other intense light.
