Document Summary
Animals: glycogen: we store glucose in muscle cells and liver cells starch (amylopectin and amylose) & fibre. Plants: amylopectin stacked of starch branching every 25-30 glucose units, amylose long chain of all the dietary starch less bioavailable it"s harder for our body to break amylose down. Starch and glycogen in our liver cells differ by the structure. Dietary fiber and starch relates to the bonds between the glucose molecules. The manner in which the glucose molecules are linked together differ in dietary fiber and starch. Fiber is non-digestible we don"t have enzymes to break these apart. Absorbing fatty acids in the food we consume. Vast majority of food provide a mix of macronutrients advantage of consuming soluble fibers while consuming lipids the fiber absorbs the fatty acids decreases cardiovascular diseases. Increase and speed the movement of chyme mobility of chyme provides less time of absorption of nutrients (lipids) decreasing absorption time - decreases the consumption of nutrients.
