C6h12o6 (isomer)differences are the arrangement of atoms in space and in relation to the rest of the molecule : structure have different function. Epimer - different at 1 positions. Very sweet main sugar in fruits and honey. Frequently added to processed food : high diertary source. Most common and important to nutrient (transported around the body) Complex sugars: disaccharides and polysaccharides. Condensation join together simple sugars. Makes water and a glycosidic bond.

Example: corn oats barley legumes citrus fruits. But it can promote bowel movement alleviate constipation and prevent diverticular disease. Note bacteria and humans shows benefit: mutralism.
