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.

Re: How much ATP a person consumes...?

It does require quite a bit of energy to break the alpha 1,4 glycosidic bond of glucose and fructose. Shouldn't that be taken into account?

Re: How much ATP a person consumes...?

Dr. Featherstone's class can be pretty challenging... This is what I got: Sucrose consists of Glucose and Fructose. Both of which can enter glycolysis (fructose can be synthesized as an intermediate in the glycolysis process). So each round of glycolysis, one molecule of glucose ...
