Document Summary

Scho (structural): cellulose, hemicellulose, lignin (which is indigestible) Classification [by # of sugar molecules: mono-, di-, oligo-, poly-] 75% sugars in honey, comes from fruits + cane sugar. Component of milk sugar (lactose), metabolized to glucose. Not as significant as the three above, from legumes. Consists of 2 monosaccharides linked by a glycosidic (acetal) bond. Table sugar produced in leaves and stems of plants. Bond fundamental for cellulose, doesn"t exist freely in nature. Homopolysaccharide (one type of monosaccharide unit, 2 kinds detailed here) Principal sugar form in animal storage + cereals. 1-4 linkages with 1-6 linkage at branch point. Heteropolysaccharide (more than 1 type of sugar unit) Mixture of glucose, mannose, arabinose, and galactose. Plant cell wall, only degraded by microbial enzymes. Indigestible, no animal or bacteria can break (end intro to cho) Only monosaccharides (glucose, galactose, fructose) can be absorbed. Specifically hydrolyzes 1-4 glycosidic bonds producing monosaccharides and disaccharides. Created in brush border, made by enterocytes, functions locally.
