Lecture 7 Vocab Malnutrition = a medical condition resulting from the lack of essential nutrients in the diet Macronutrients = nutrients that organisms must ingest in large amounts to maintain health (EX. Carbs, proteins, lipids) Digestion = process of breaking down huge food molecules into smaller pieces so that our body can use them Metabolism = all chemical reactions occurring in the body Catabolic reactions = break down larger structures into smaller ones Anabolic reactions = build new structures from smaller subunits Enzyme = protein that speeds up a chemical reaction Substrate = molecule to which an enzyme binds and on which it acts Active site = part of an enzyme that binds to the substrate Catalysis = the process of speeding up the rate of chemical reaction Activation energy = energy required for a chemical reaction to start Micronutrients = nutrients. Including vitamins and minerals, that organisms must ingest in small amounts to maintain health Cofactors = Inorganic micronutrients required to activate an enzyme Coenzymes = Small organic molecules required to activate enzymes Minerals = inorganic elements required by organisms for normal growth, reproduction, and tissue maintenance Vitamins = organic molecules required in small amounts for normal growth, reproduction, and tissue maintenance Complete foods = foods that contain all the nutrients necessary RUTF = Readytouse food therapeutics Balanced diet = fruits, vegetables, and whole grains making up most of your diet Lecture 7 Information Malnutrition is the number one killer of children around the world More children die each year from malnutrition than from AIDS, TB and Malaria Combined Macronutrients are large molecules They must be broken down through digestion to be fully used Macronutrients Proteins Broken down into amino acids Used to assemble new proteins that have many different functions in the body Carbs Broken down into simple sugars Used to build cellsurface markers, energystorage molecules Fats Broken down into fatty acids and glycerol Used to build molecules that form call membranes Used to assemble the phospholipids that make up cell membranes Nucleic acids Are NOT macronutrients Provided in SMALL mounts Used to build DNA and RNA Broken down into individual nucleotides Essential Nutrients Cells cannot synthesize them Must be obtained through diet Essential amino acids 20 amino acids used to build proteins 9 cannot be synthesized Digestion A series of chemical reactions to break down the bonds that hold food molecules together Starts in our mouths and continues throughout the digestive system Metabolism The assistance of helper molecules called enzymes Micronutrients Minerals act as cofactors Vitamins act as coenzymes The Peanut Butter Project Nonprofit organization using peanut butter to end malnutrition in Africa Peanut butter, fullfat milk, sugar, vegetable oil
