Document Summary

Regulation of metabolism and body temperature: absorption of carbohydrates. For carbohydrates to be absorbed, they have to be monosaccharides. Common protein carriers more glucose and galactose into epithelial cells using active transport involving na+. The movement of monosaccharides into blood capillaries occurs by facilitated diffusion. There are several types of amino acid carriers that go through secondary active transport (na+). These carriers recognize groups of amino acids (acidic, basic, neutral). Some di- and tripeptides also actively are transported into epithelial cells and are digested to single amino acids within the cytoplasm. Intestinal mucosa of infants is immature and may permit some uptake of whole proteins, leading to food allergies and transport of breast milk-derived iga antibodies (temporary passive immunity): absorption of lipids. Bile salts are necessary for the absorption of lipid digested products. Monoglycerides, glycerol, and ffa are water-insoluble, so once generated by lipases they associate with bile salts and lecithin (phospholipid) to form micelles (droplets).
