| phosphotyrosine | <biochemistry> Strictly speaking, tyrosine phosphate, but normally refers to the phosphate ester of a protein tyrosine residue. Present in very small amounts in tissues, but believed to be important in systems that regulate growth control and is therefore of interest in studies of malignancy. The src gene product (pp60(src)) was one of the first kinases shown to phosphorylate at a tyrosine residue. (18 Nov 1997) |

| phosphuret | <chemistry> A phosphide. Source: Websters Dictionary (01 Mar 1998) |
| phosphureted | <chemistry> Impregnated, or combined, with phosphorus. Alternative forms: phosphuretted] Phosphureted hydrogen. <chemistry> See Phosphine. Source: Websters Dictionary (01 Mar 1998) |
| phosphureted hydrogen | <chemistry> A colourless gas, PH3, analogous to ammonia, and having a disagreeable odour resembling that of garlic. Synonym: hydrogen phosphide, and formerly, phosphureted hydrogen. It is the most important compound of phosphorus and hydrogen, and is produced by the action of caustic potash on phosphorus. It is spontaneously inflammable, owing to impurities, and in burning produces peculiar vortical rings of smoke. Source: Websters Dictionary (01 Mar 1998) |
