Document Summary
Main fuel source for some of the body"s cells. Brain, nerve cells, red blood cells, exercising muscle. About 50% or more of our calories come from carbs. Co2 + h2o + light cn(h2o)n +o2. Cn(h2o)n +o2 energy + co2 + h2o. Monosaccharides: mon means one, this is the basic unit of all carbohydrate structures. Formed by the chemical bonding of two monosaccharides. Derived mainly from the digestion of starches and disaccharides. One dietary source is high fructose corn syrup. Part of the disaccharide lactose (milk sugar) Also known as polysaccharides: poly means many. May contain 1000 or more glucose units. Cooking: softens fibrous parts of plants, starch granules swell with water making it easier to digest. Pancreatic amylase breaks starches in di- and trisaccharides, and. Disaccharidases: located in the brush border of the cells that line the inside of oligosaccharides the small intestine. Often develops in earlier childhood (3-5 years old). Cause by a decrease in lactase production (activity)
