Biology 1201/ September 7 Pre-reading: 142-162 Classes if organic molecules: Types of carbohydrates: Monosaccharides : 1 sugar Disaccharides : - 2 sugars -Produced through condensation reactions -figure I drew in class -figure 5.2 -synthesis of sucrose Polysaccharides : many sugars -cellulose: structural -starch: storage(plants) -glycogen: storage(animals) -figure 5.7 and 5.8 -A polysaccharide (carbohydrate) made from 5 glucose (C 6 H 12 O 6 ) molecules joined together would have the molecular formula: C 30 H 52 O 36 (making 4 bonds.????) Lipids: -lipids are based on solubility -based on how they are insoluble in water -they are non-polar TYPES OF LIPIDS: -Fatty acids -Hydrocarbon (one of acidic function groups; non polar) chain with a carboxyl (polar) group on one end. Since hydrocarbon is larger, it is non polar -figures of saturated and unsaturated fats(carbon carrying

Unformatted text preview: pure hydrogen) pic of::: saturated-single bonded unsaturated-double bonded-Triglycerides (fats)-a glycerol molecule with 3 fatty acid chains attached-pic of “components of a triglyceride”-saturated-Phospholipids-a glycerol molecule with 2 fatty acid chains and a phosphate group attached. -Figure of phospholipid (right side non polar, left is polar)-Steroids-4 carbon rings with various side groups.-figure 5.14 (colesterol)-all have 3 six sided rings and one five sided ring (carbon rings) ****which most likely represents a lipid? C 8 H 16 O 2 because it has less oxygen and 1-3 has the 1,2,1 format and this answer did not. Carbon lots of hydrogen and not a lot of anything else. Proteins:-polymers of amino acids-unbranched chains...
