Ketose is the only ketohexose sugar

WebKetose is a monosaccharide whose carbon skeleton has a ketone group. Only in the presence of reducing sugar, they can isomerize to aldose. They are used in processed food.

Web5 feb. 2024 · Abstract. A facile approach is introduced here for the synthesis of rare ketoses from glycerol and d-/l-glyceraldehyde (d-/l-GA). The reactions were carried out in a one-pot multienzyme fashion in which the only carbon source is glycerol. In the enzymatic cascade, glycerol is phosphorylated and then oxidized at C2 to afford dihydroxyacetone ... http://chem.ucalgary.ca/courses/351/Carey5th/Ch25/ch25-2-4.html light pink and purple flannel shirt https://itsbobago.com
