triose Chem.|ˈtraɪəʊs|
[f. tri- 5 + -ose2.]
1. a. Group name of the sugars containing three atoms of carbon, C3H6O3; the two possible cases are aldotriose, CH2OH.CHOH.CHO, and ketotriose, CH2OH.CO.CH2OH. b. It has also been used as a group name and as a termination for the trisaccharides, i.e. those sugars which break up on hydrolysis into three simple sugars.
1894Muir & Morley Watts' Dict. Chem. IV. 531 [Sugars] are designated according to the number of carbon atoms they contain: thus, pentose containing C5,..Triose C3H6O3, glycerose. 1894M'Gowan Bernthsen's Org. Chem. (ed. 2) 317 Sugars of the above [cane sugar] group are termed ‘-bioses’, e.g. milk sugar is lacto-biose. Similarly raffinose is a ‘-triose’, Mele-triose. 1895Athenæum 26 Jan. 123/1 [A paper] ‘Presence of a Triose in Starch Transformation Products’ [was read].
2. Special Comb.: triose phosphate, any compound in which a hydrogen atom in the hydroxyl group of a triose is replaced by a phosphate group (PO32-).
1934Chem. Abstr. XXVIII. 3746 Triosephosphate was sepd. by fractional pptn. with EtOH and Me2CO. 1982R. A. Harris in T. M. Devlin Textbk. Biochem. vii. 336 Triose phosphate isomerase then catalyzes the reversible interconversion of dihydroxyacetone phosphate and glyceraldehyde 3-phosphate to complete the splitting stage of glycolysis. |
