Document Summary
Learning goals: differentiate between the types of carbohydrates, list the steps involved in the digestion of carbohydrates, explain the concept of lactose intolerance, state the dietary requirements of carbohydrates. "sugar-replacers" for glucose and sucrose in products: e. g. Glucose and fructose, 2 of the sweetest monosaccharides, participate in cell metabolism. Galactose is converted to glucose by the liver. Tagatose is an isomer of fructose, and is 90% sweeter than sucrose. Hydrolysis reaction during digestion breaks apart disaccharides. Maltose is produced when starch breaks down. Table sugar is sucrose that has been refined and granulated from sugarcane. Glycogen is the storage form of glucose. It is made of many glucose molecules, and is found in the liver and muscle. Amylose is a starch found in plants (rice, wheat, barley, legumes and potatoes) and is made of many glucose molecules. Cellulose is an example of dietary fibre, which is the structural component of plant cell walls.
