Document Summary
Nutrients function to provide energy, promote growth & development and regulate body processes. Glucose (all carbs break down into this, which is what we absorb) Used directly by the cell for energy. Stored as glycogen in the muscles and liver for later use (there is a capacity) Converted to fat and stored for energy. The body converts galactose to glucose for energy metabolism. Plant starch accounts for 50% of the total carbohydrate intake of. The term complex carbohydrate commonly refers to dietary starch. Resists hydrolysis by human digestive enzymes, but offers health benefits. Storage polysaccharide found in the muscle and liver. Glycogen is synthesized from glucose during gluconeogenesis. Glycogenolysis is the reconversion process-it provides a rapid source of glucose. Retains water and provides bulk to the food residues in the intestines. Shortens transit time for food residues to pass through the digestive tract. Hormones help to regulate blood sugar levels. Glucagon stimulates liver glycogenolysis and gluconeogenesis to raise blood.
