Document Summary
Carbohydrate family: monosaccharides, simple carbs, disaccharides, pairs of monosaccharides, simple carbs, polysaccharides, chains of monosaccharides, complex carbs. All have same number and kind of atoms (c6h12o6) but differ in arrangement. Hydroxyl (oh) and (h) combine and create h2o. H2o splits to provide h and oh to complete the 2 monosaccharides. Made when starch breaks down during digestion or during fermentation. Make glycogen (storage for humans), starch (storage for plants) and fiber (structure in plants) Glycogen and starch are made from just links of glucose. Stores glucose for use in the future. Found in a limited extent in meat so food is not a good source of glycogen. Branched (amylopectin) or unbranched (amylose) chains of glucose. Dietary fiber: structural part of the plant. Bonds cant be broken down by digestion so they contribute little energy. Soluble fibers (dissolve in water), viscous (forms gels), and fermentable (digested by bacteria) Protect against heart disease and diabetes by lowering glucose and cholesterol.
