polysaccharides
Type of carb:
One sugar molecule
hexose (6 carbon)
fructose, glucose, galactose ** Answer** Monosaccharide
Type of carb:
2 sugar molecules
maltose, sucrose, lactose ** Answer** Disaccharide
Type of carb:
Few sugar molecules (3-10)
indigestible; bacterial ** Answer** Oligosaccharide
cannot be broken down by enzymes ** Answer** Indigestible
Type of carb:
contain many glucose molecules (more than 10)
some are more digestible, some are indigestible
starch, glycogen ** Answer** Polysaccharide
What are the two digestible polysaccharides? ** Answer** Starch
glycogen
, ** Answer**
Digestible polysaccharide
Stored from glucose in animals
small amounts in liver
