Document Summary

& complex carbohydrates (staan&fibers) y simple mono dels accharides. Lo mono saccharides glucos, fructose, or galactose; absorbed. Is disaccharides a courlendy honded, lactose, sucrose, mattose, trehalase to complex & oligo & polysaccharides. Ls lactose - linkage (milk sugar) (iglucose, 1 galactose) to sucrose o linkage (table sugar) (1 glucose, 1 fructose) Sgl7l on brush border uses na+ as transporter, 3:1 ratlo glucose lgalactose on baso-lateral site pumps nat in dat out. Glut-2 transports all 3 monosaccharides to submucosal side to low affinity, high capacity transporter y can be in lumen to help transport sugars. Increase in sugar increase of insulin in circulation no glut-2 on laman. Proteins become dipeptides, tripeptides, or amino acids. Once inside, di- & tri-peptides are usually converted to a mano acids. 4280% begin as di- & tri-peptides 98% enter the blood stream peptides pept 1 transporter wactive transport for.
