Document Summary
Carbohydrate hydrate of carbon ; manufactured by plants: making a glucose molecule, eg/ making a glucose molecule. 6 co2 + 6 h2o + energy c6h12o6 + 6 o2. Storage form of glucose: animals glycogen. Glycogen branches at points; compact manner; liver higher in glucose; 8-10 glucose units then branch: plants starch (amylopectin and amylose) and fiber. Amylopectin more bioavailable; starch; branched linear chains 25-30 glucose units, then branch. Amylose of all starch available in plant based sources; less bioavailable than amylopectin (more compact) Fiber non-digestible carbohydrates (in plants); our bodies do not have the enzymes to breakdown certain fibers: soluble fibre. Forms a gel in gi system does not move fast. Decreases cardiovascular disease, because less cholesterol is absorbed into body. Slows gastric/intestinal motility advantage; absorbs fatty acids consumed with this fiber. Decreases type ii dm because increased motility decreases glucose absorption time.
