NUTR 221 Lecture Notes - Lecture 3: Avocado, Vitamin K, Nutrient Density
Document Summary
Vitamins: organic compounds that contain carbon, hydrogen and other atoms (nitrogen, oxygen, phosphorus, carbon based. Function: break down atoms and molecules in macronutrients, energy extraction from macronutrients, calcium balance, blood clotting (vitamin k) Minerals: an inorganic nutrient that is needed for growth and regulation of normal physiology. Macrominerals: major minerals required in the diet in larger amounts than the trace minerals: na, k, cl, ca, p, mg, s, na levels too low can predispose to health problems, need to balance ions/electrical level in body. Trace minerals: required in small amounts in the diet. What is energy? lomoarcpsd: an ability to cause changes in, or perform, work, heat and/or mass, common de nition: ability to perform work. 30% is used for usable mechanical energy, most of energy is released as heat: chemical - binding/unbinding of bonds, nuclear - binding/unbinding of nucleons.
