Document Summary

Changing american diet: dairy goes down, fruits and vegies constant, fats and oils increase substantially, rice gown up, oats constant, whole wheat flour went up, beef gown down, chicken increased dramatically, total added fats gown up, Changes in diet from 1970 to 2006 (us): 16. 4 to 18. 2 (11%) lb per week. Total supply of food available for consumption gone up. Sucrose: two fragments: glucose + fructose linked by oxygen monosaccharides, making a disaccharide. This bond can be broken by an enzyme invertase or invert sugar 50/50 glucose/fructose. Our bodies use carbohydrates to create energy oxidation. Energy from the sun + water + carbon dioxide (plants) carbohydrates+ o2 (glucose) Glucose converted back into glucose and carbon dioxide (glucose oxidation) Stereochemistry h down and up switch is different sugar. Methane molecule: black middle is carbon with 4 white hydrogen. 6 membered ring with 1 oxygen and 5 carbon.
