Undernourishment:   the daily caloric intake is insufficient to meet the metabolic needs  of a person CARBOHYDRATES:   What form do they take in the body? (Chain together to create  Glycogen; stored in muscles and liver, a quick source of energy) o Contain C, H, O with the H and O in a 2 to 1 ratio o 5 or 6 sided rings with 1 O atom, the rest C atoms, OH groups and ROH groups  attached to rings wherever else there are H atoms Monosaccharide:   only one ring (single sugars) o Examples: Alpha Glucose, Beta Glucose, Beta Fructose Disaccharide:   two rings joined by Oxygen, or a combination of two monosaccharides.  (double sugars) o Formed by condensation reaction, H and OH split off (water is given off) Alpha Glucose + Beta Fructose = Sucrose Polysaccharide:   multiple rings joined by ‘O’, made up of THOUSANDS of glucose  units o Formed by condensation reaction, natural polymer of many monosaccharides with the  Oxygen link Examples: Starch, ‘Spuds’ (potatoes), cellulose (paper), glycogen (body  storage for carbs) o AKA ‘Complex Carbohydrates’ Starch:   alpha linkage (which you can digest) Cellulose:   beta linkage (you cannot digest) Glycogen:   similar to starch, but longer and more branched,  stored in muscles and liver FATS AND OILS : Part of lipid family, includes cholesterol, steroids, etc. o All fats and oils are triglycerides, an ester of 3 fatty acids and one glycerol Oil:   triglyceride that’s liquid at room temp. Fat:   triglyceride that’s solid at room temp. OIL: Oils:  Unsaturated; contains fatty acids         with 1 C=C cannot pack in tightly, liquid
