Fructose

Fructose

(Science: biochemistry) a 6 carbon sugar (hexose) abundant in plants. Fructose has its reducing group (carbonyl) at C2 and thus is a ketose, in contrast to glucose that has its carbonyl at C1 and thus an aldose. Sucrose, common table sugar, is the nonreducing disaccharide formed by an alpha linkage from C1 of glucose to C2 of fructose (latter in furanose form). Fructose is a component of polysaccharides such as inulin, levan. A simple Sugar found in honey and in many ripe fruits.

can galactose be convert into fructose?

monosaccharides can be converted into one other, otherwise you could never utilize any other sugar than fructose or glucose. Galactose for example can be converted to glucose via Galactose-1-phosphate uridyl transferase. fructose can be phosphorylated by fructokinase, from ...
