| thiocyanate | <chemistry> Same as Sulphocyanate. Source: Websters Dictionary (01 Mar 1998) |
| thiocyanate hydrolase | <enzyme> A novel enzyme catalysing the formation of carbonyl sulfide and ammonia from thiocyanates; mw 126 kD; from thiobacillus thioparus Registry number: EC 3.5.99.- (26 Jun 1999) |
| thiocyanates | Organic derivatives of thiocyanic acid which contain the general formula r-scn. (12 Dec 1998) |

| thiocyanogen number | The number of grams of thiocyanogen taken up by 100 g of fat; analogous to the iodine number, except that thiocyanogen will not add to all the double bonds in polyunsaturated fatty acids as will iodine. Synonym: thiocyanogen value. (05 Mar 2000) |

| thiodepsipeptide | Peptides that also contain one or more acylated thiol groups (e.g., of cysteine). Origin: thio-+ G. Depseo, to knead, blend, + peptide (05 Mar 2000) |
| thiodiphenylamine | <pharmacology> A group of tranquilising medications with antipsychotic action, thought to act by blocking dopaminergic transmission in the brain. They are used to treat mental, nervous and emotional disorders. Examples include: chlorpromazine, fluphenazine, mesoridazine, perphenazine, prochlorperazine, promazine, thioridazine, trifluoperazine, thiopropazate and triflupromazine. Trifluoperazine binds to and inhibits calmodulin and has been used experimentally to block calcium or calmodulin controlled reactions. (29 Sep 1997) |
| thioester | Compounds of the type. R CO s R. See: coenzyme A, palmitoylation. (18 Nov 1997) |
| thioesterase | <enzyme> An enzyme that hydrolyzes thioesters; e.g., the deacylating activity at the end of fatty acid biosynthesis that releases palmitate. Synonym: thiolesterase. (05 Mar 2000) |
| thioesters | In enzymology, an ester where the oxygen bridging the substrate or product carbonyl carbon and the enzyme is replaced by a sulphur (usually through a cys residue); a high energy intermediate in many enzymes. (05 Mar 2000) |
