Document Summary
Q: hiv is an rna virus & is an envelope virus. Readily usable source of energy for cells. Also used for structural components cellulose in plant cell walls (rigidity) Polysaccharides more than 2 sugars joined together. Plants store glucose in the form of starch. Animals store glucose in the form of glycogen. Starch, glycogen, & cellulose are all glucose polymers. Starch is digestible alpha 1,4 bonds. Body creates enzymes that can digest those bonds. Makes up the bulk of our diet. Cellulose is indigestible beta 1,4 bonds. Body does not create enzymes to break these bonds. When we eat fiber, we cannot digest it. Glucose in cellulose is useless to use; we don"t get energy from it. Example of how sugars can be for structure in addition to energy. Saturated fats maximum number of h atoms & no double bonds. Unsaturated fats have at least one double bond.
