NTR 312 Study Guide - Midterm Guide: Chno-Fm, Parietal Cell, Gastrin
Document Summary
Chno make up about 96% of all living organisms. 6 classes of nutrients carbs, protein, lipids, vitamins, minerals, water. Amdr carbs are 4 kcal/gram, fats are 9, proteins are 4, alcohol is 7: 45-65% carbs, 10-35% proteins, 20-35% fats. Estimated average requirement meets requirements for 50% population. Recommended dietary allowance (rda) meets requirements for 98% Ai not enough research for rda. Tolerable upper limite (ul) highest safe dose. Amrd proportion energy from carbs, fats, proteins. Diet planning: adequacy, balance, variety, moderation. Functional food serves some kind of health purpose. Nutrient claims: high 20%+ dv, good source of 10-15% dv, low less than 5% Mouth secrete salivary amylase and lipase to digest carbs and fats. Chief cells secrete pepsinogen to become active pepsin: digests protein. Hormones of digestion carboxypeptidase (proteins lipase (lipids sucrose, maltase, lactase (sugars) Gastrin secreted in the stomach"s g cells.
