Document Summary

Unit 5: explain the origin of dietary carbohydrates. Sugars, starches, and most kinds of fiber are carbohydrates: categorize the different carbohydrates as either mono- , di- or polysaccharides. Monosaccharide: the si(cid:373)plest t(cid:455)pe of suga(cid:396), a (cid:862)si(cid:374)gle suga(cid:396)(cid:863: the basic chemical unit of carbs, 3 most important monosaccharides. Fructose: (fruit sugar; levulose) is found naturally in fruit, honey, and a. Disaccharides: a sugar comprised of two monosaccharides. few veggies. Body usually turns fructose to glucose: 1.

Polysaccharides: compounds comprised of 10 monosaccharides bonded together: eg: starch and glycogen, identify carbohydrate storage both in plants and animals. Plants: plants store glucose as polysaccharides called starch. Your intestinal tract can digest starch into individual glucose molecules that can be absorbed. Animals: store glucose as a polysaccharide called glycogen.
