sedoheptulose Chem.|siːdəʊˈhɛptjʊləʊz, -s|
[f. sedum + -o + hept)ose s.v. hepta- + -ulose2.]
A heptose that is found in the leaves of certain plants of the genus Sedum (notably S. spectabile), a phosphate of which is involved as an intermediate in carbohydrate metabolism in animals. Formerly called † sedoheptose.
1917La Forge & Hudson in Jrnl. Biol. Chem. XXX. 68 Since the analyses of the three crystalline derivatives that have been described show conclusively that the sugar of Sedum spectabile contains seven carbon atoms, it will be named, with reference to its origin, sedoheptose. 1938Thorpe's Dict. Appl. Chem. (ed. 4) II. 286/2 The natural ketoheptoses are d-mannoketoheptose..; perseulose.., and sedoheptose obtained from Sedum spectabile. 1939Jrnl. Amer. Chem. Soc. LXI. 343/2 In the presence of mineral acids, sedoheptulose is transformed to a crystalline anhydride. 1959[see ribulose]. 1970R. W. McGilvery Biochem. xvi. 325 The only known function for the 7-carbon sedoheptulose-7-phosphate in animals is its participation as an intermediate in the pentose phosphate pathway. |
