Document Summary
Gene presence vs. gene expression: epigenetics. Secondary set of instructions responsible for changing phenotype. How siblings can have the same dna but different phenotypes. Changes in hunger cues: dna methylation epigenetic mechanism used by cells to control gene expression. The higher the methylation, the healthier the dna. Nutrigenetics how our genes affect nutrient absorption, metabolism, nutrient requirements and food/nutrient tolerances i. e. inheriting a genetic mutation that inhibits the synthesis of a certain digestive enzyme. Carbs 4cal/gram glucose, galactose and fructose the three monosaccharides that. Chapter 7 review we eat: main function is energy, stored as glycogen if glycogen stores are full, extra carbohydrates are turned into fat. Lipids 9cal/gram fatty acids, glycerol: main function is energy, stored as triglycerides in adipose tissue. Nitrogen is formed into urea sent to kidneys and excreted in urine. Amino acid without protein is called alpha keto skeleton gets turned into glucose or ketones.
