Document Summary
Essential nutrients: they get water and ions through the roots. Organic molecules oxidized to produce energy- atp. Unequal amounts of energy produced by different molecules. Calorie= energy required to raise 1 ml of water 1 degree celsius; food calories are kilocalories. 3 carbons and ester groups attached to each molecule with ester linkage (yellow-fatty acids) Start with the oxygen that is in the ring, and number the carbons clockwise. Starch- alpha 1-4 (storage) amylose, and amylopectin. Composed of amino acids: central carbon, amino group, h. Proteins: contain both carbon and nitrogen, ingested amino acids > other amino acids > proteins for most every cellular function. Lipids: fatty acids + glycerol > membrane phospholipids, cholesterol > hormones. Substances the body is unable to synthesize from organic precursors: essential amino acids, essential fatty acids, vitamins, minerals. Malnutrition: state of insufficiency of an essential nutrient. W (omega) 3 and w6 polyunsaturated fatty acids (pufa) Needed to make membrane phospholipids (linoleic acid)
