Document Summary
Links are able to broken down by enzymes. Mammals do not possess the enzymes to break the links/bonds between ms. The alpha linkages that hold starch together - readily digested/broken by animal"s enzymes. The beta linkages in cellulose and hemicellulose (hays, grasses) - not able to be digested. Dietary carbohydrates must be converted into simple sugars (ms) for absorption. Primary source of amylase is the pancreas. Other enzymes from mucosal lining of the duodenum. If dietary carbohydrate levels exceed the animal"s ability to digest it, diarrhea may occur! Water is reabsorbed into gi and causes diarrhea. Monosaccharides are rapidly absorbed by the small intestine. Transported via blood to be metabolized as energy source = fuel for metabolism. Some glucose is converted into glycogen (rapidly releasable form of energy during times of excessive exercise) Glycogen is also involved in regulation of blood glucose - maintained in narrow range.
