BIOL 100 Lecture Notes - Lecture 4: Peanut Butter, Sub-Saharan Africa, Glycogen
Document Summary
Biology for a changing world: the peanut butter project: Found they can take peanut butter add a supplement to make it a child"s diet. A medical condition resulting from the lack of essential nutrients in the diet. #1 cause of death of children around the world. Nutrients: the chemical building blocks our bodies need to live, grow, and repair themselves, provides energy. Energy: the ability to do work, macronutrients: Nutrients that organisms must ingest in large amounts to maintain health. Carbohydrates, proteins, lipids (fats: food provides macronutrients: A varied diet must include vegetables, oils, grains, meat, dairy products. Many foods contain all three types of macronutrients. Animal products contain more protein per gram: macronutrients are large molecules: Must be broken down into smaller units. Use subunits as building blocks or energy. Used to build cell-surface markers, energy storage molecules. Short term storage (glycogen, ( muscle, liver ) Long term storage (adipose : macronutrients : proteins.
