Document Summary
Cho are made up of carbon, hydrogen and oxygen atoms. Disaccharide: formed by combining 2 monosaccharides (ex: sucrose, lactose, maltose) Polysaccharide: complex cho containing 3+ monosaccharides (ex: starch, glycogen) Glycogen storage reservoir for carbs and energy. Glucogenesis: glycogen synthesis from glucose in mammalian muscle and liver cells (glucose glycogen, catalyzed by the enzyme glycogen synthase) Gluconeogenesis: glucose synthesis largely from structural components of noncarbohydrate nutrients (protein glucose) Once produced, glucose can follow one of 3 pathways: Become available as an energy source for metabolism, both anaerobic glycolysis (end-product=lactate) and aerobic glycolysis (end-poduce=pyruvate) (oxidative phosphorylation) Form glycogen for storage in the liver and muscles (glucogenesis) Convert to fat (triacylglycerol) for later use as energy. Glycogenolysis: glucose formation from glycogen (glycogen glucose) Cho is stored with mammalian liver and muscle as glycogen, where is 1 gram of glycogen/glucose = 4 k cal of energy. Carbs alone is 2012 kcal o o o.
