Document Summary
Macro and micronutrients supply us with energy: we need calories from macronutrients, micronutrients are more like vitamins and minerals being used as cofactors and coenzymes to run our body processes. *read the introductory beginning chapter of this topic in the textbook. The goal is to use the dietary foods to produce energy to run the processes in the cell. Lactase can break down the beta bond between the two units of lactose. The first step in utilization or storage is digestion, using various enzymes at different areas in the digestive tract. Once the starches and disaccharides are broken down to monosaccharides they can be absorbed into the body. The important part is knowing whether or not we have the enzyme to break this bond down. Enzymatic breakdown of carbohydrates occurs by hydrolysis reactions. A water molecule is used in the breaking of the bond. The different enzymes involved in carbohydrate digestion work at different phs.
