what is a disaccharide
two monosaccharides joined together to form a disaccharide by dehydration synthesis they are joined by a covalent bond called glycosidic linkage between specific hydroxyl groups
what's a polysaccharide
many monosaccharides joined together
what does starch do
energy storage for plants energy source for humans amylase enzyme breaks down starch and is used in cellular respiration
what does cellulose do
it's a component of the plant cell walls important to the structure and form in humans are unable to digest the linkages between the beta glucose and cellulose FIBER
what is glycogen
it's an energy storage molecule animals, excess glucose is converted to glycogen for storage in the cells of liver and muscles
how is glycogen broken down
enzymes break down glycogen during exercise to release glucose
which glucose can humans easily Digest

beta glucose
