Measured in c (calorie) = 1 kilocalorie = 1000 calories; 1 cal = heat required to raise 1 kg h2o by 1 degree celsius. Carbs (4 c = 1 g), protein (4 c = 1 g), lipids (9 c = 1 g) Carbs not essential humans get sufficient e from other sources. Need s, organic n to make half of proteins. Must ingest other 8 essential aas in adults, 9 in infants. Animals can synthesize fatty acids but lack enzymes to form double bonds. Found in seeds, grains, (include all aas needed) Incomplete proteins: plant sources (does not veggies = deficiencies are rare include all aas) Many are coenzymes - required for proper enzyme function. Ca - bones, teeth, clotting: water soluble: cannot be stored; excreted in synapses, muscles urine. P - bones, teeth, atp: b complex vitamins: b3 (component.
