NUTRI 130 Lecture Notes - Lecture 5: Adipose Tissue, Blood Sugar, Glycogen
Document Summary
Be able to define/identify the three disaccharides. Enzymes break down into glucose and fructose components. Stored in liver and muscles of humans and animals as storage form of glucose. What is glycogen"s role in the body? storage form of energy. Define the three types of polysaccharides important in nutrition. Plant polysacch composed of glucose and digestible by human beings. Digestive enzymes cannot break bonds, some can be digested by bacteria. Facilitates glucose uptake by muscles and adipose tissue. Breaks down glycogen into glucose molecules when blood sugar is too low. Higher obesity rates correlated with increased consumption of added sugars. Moderate amounts of sugar do not cause obesity. Fructose can lead to unhealthy build-up of lipids in heart and arteries. Foods high in sugar often very low in nutrients. Sugar influences bacterial growth in the mouth, eats away at tooth enamel.
