Document Summary
Hfcs 55 (mostly used in soft drinks), approximately 55% fructose and 42% glucose. A study done at princeton, researchers find that hfcs prompts considerably more weight gain: hfcs may increase the obesity in may people. They are long chains of sugar units. They are polymers of monosaccharides: three or more sugars hooked together. Cellulose is known as dietary fiber: most animals cannot get nutrition from fiber. But you need it in your diet. We get digestive health from fiber and grab cholesterol. Types of lipids: triglycerides, phospholipids, steroids. Composed of two types of molecules: glycerol and fatty acids, glycerol has all single bonds, fatty acid has double bond. Store higher amounts of energy per gram than carbs do. Insulation of warm blooded animals: cushion internal organs. Healthy fats: fats with omega-3 fatty acids reduce the risk of heart disease. Similar to neutral fats in that they are composite molecules. Contain: glycerol, 2 fatty acids, po4 (phosphate group)
