Digestion Physiology

1. DIGESTION- Breakdown of food to small enough molecules that can cross(a) the epithelial cells lining intestinal tr do and enter the hairlike melodic phrase or lymphatic capillaries. Physical (mechanical)-chewing, tearing, mixing. Chemical uses enzymes and other(a) molecules. 2. POLYSACCHARIDES- (complex carbohydrates) Starch, glycogen, cellulose. (many covalently bonded monosaccharides) 3. DISACCHARIDES- Sucrose milk sugar Maltose. (two covalently bonded monosaccharieds) 4. MONOSACCHARIDES- (simple sugars) glucose, fructose, galactose. 4a. CARBOHYRATE ENZYMES- *amylase, maltase, sucrase, lactase 5. PROTEINS- have four levels of structure: *Primary- season of aminic acids. *Secondary- shape: ?-helix, ?-pleated sheets *Tertiary- 3D shape: Fibrous (pleated sheets or considerable chain of helices. Insoluble in water geomorphologic component). spherical (folds back on itself making complex shapes. Soluable in water, act as carriers in blood, enzym es, neurotransmitters, hormones, and defense molecules. * Quadterinary- several protein gyves that associate to formulate a functional protein. (ex. Collagen and hemoglobin). *found in animal products, barmy, grains. 6. PROTEIN ENZYMES- *pepsin (s) endo. *trypsin (P) endo. *chymotrypsin (p) endo. *carboxypeptidase (p) exo. 6a. amino ACIDS *glycine, alanina, valine 7.

TRIGLYCERIDE- *constructed of single glycerol (half of a sugar) and ternion fatty acids. compliance of fat we mostly eat. * found in animal products, nuts 7a. FAT ENZYMES and EMULSIFIER * Bile (emulsifier): released into 1st of small intestine; breaks blown-up globs of fat int o small globs of fat. Made by coloured and ! stored in gall bladder. * lipase and colipase: from pancreas digests triglycerides to yield free fatty acids and monoglycerides for absorption. 10. low-pitched intestine PARTS: *duodenum *jejunum *lleum 11. SECRETION: *transepithelial transfer of water and ions from extracellular legato to digestive tract & release of substances synthesized...If you want to get a full essay, order it on our website: OrderEssay.net
