Document Summary
Calorie aka kcal = kilo-calorie, 1000 gram-calories (calorie), to heat 1 kilo of water by 1 degree celcius. Macronutrients = carbs, fats, proteins, alcohol, essential, provide us eith energy: 1) carbohydrate = provide energy 4kcal/g, body gets energy from carbs, important type of carb is glucose. * goal of carb digestion = to obtain glucose. Monosaccharides = body can use these directly, include: glucose, fructose, galactose. Disaccharides = have to have enzyme to break up the two molecules in order to digest these (digested into monosaccharides in order to be absorbed into blood stream), taste sweet, include: maltose, sucrose, lactose. Starch = the storage form of glucose in plants, a polymer of glucose: 2) fat = 9 kcal/g, provide essential fatty acids, provide energy, most dense of macronutrients. Triglycerides = glyceral molecule with 3 fatty acids hooked into it (chains) Fatty acids = long chains of carbon and hydrogen moleucles which provides usable energy, provide points of unsaturation.
