Document Summary
Glucose fuels nearly all of the brain"s activities. Provide for about half of all energy needed. Polysaccharides: large molecules composed of chains of monosaccharides. Each atom has a characteristic number of bonds it can form with other atoms. Notice that in this simple molecule of ethyl alcohol, each h has one bond, o has two, and each c has four. All three monosaccharides have the same numbers and kinds of atoms. Glucose molecules linked together in highly branched chains. Glucose molecules linked together in branched or unbranched chains. Are easily digest by bacteria in the colon. Found in oats, barley, legumes, and citrus fruits. The salivary enzyme amylase starts to hydrolyzing starch to shorter polysaccharides and to the disaccharide maltose. Sucrase breaks sucrose into one glucose and two fructose molecules. Lactase breaks lactose into one glucose and one galactose molecule. Fibers attract water, which softens the stools for passage without straining.
