Cause change in physical characteristics and chemical properties. Ketone c=o is located in carbon chain. Aldehyde c=o is located at the end of a carbon chain. Hydro-carbon (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Polar: hydroxyl, carbonyl, carboxyl, amino, phosphate, sulfhydryl. Carbohydrates: compounds with ratio of 1c:2h:1o, monosaccharides 1 sugar, disaccharides 2 sugars, polysaccharides many sugars, figure 5. 3, figure 5. 04, disaccharides. Figure 5. 2: difference between dehydration and hydrolysis, polysaccharides. Lipids: lipids are insoluble in water, non polar, fatty acids. Hydrocarbon chain with a carboxyl group on one end. A glycerol molecule with 3 fatty acid chains attached. A glycerol molecule with 2 fatty acid chains and a phosphate group attached: triglycerides (fats, phospholipids. 4 carbon rings with various side groups.
