Document Summary
Carbohydrates: carbon and water carbon, hydrogen and oxygen in a ratio of 1:2:1 soluble in water and contain usable energy manufactured by plants using energy from the sun (photosynthesis) Disaccharides: double sugars 2 monosaccharaides bound together: sucrose: glucose and fructose common table sugar which is abundant in some plants sugar cane, sugar beets. Turns into some glucose, however only one unit of glucose unit: lactose: glucose and galactose found in milk, maltose: glucose and glucose. Cereal grains and malt liquors product of starch breakdown. Raise blood sugar more quickly because 2 glucose molecules are given off. Glycemic index: how quickly carb will be converted into glucose: low: slower rate of conversation. When 2 monosaccharaides come together it is called condensation: condensation release water; hydrolysis requires water, break apart disaccharide water has to go into digestive process: hydrolysis. Amylose: main form of starch found in carbs straight chain polymer.
