BIOL 150 Lecture Notes - Lecture 5: Chitin, Peptidoglycan, Glycogen
Document Summary
Oligosaccharides - short chains of more than 2 sugars, less than 10. Polymers = starches, glycogen, cellulose, chitin, and other large molecules made up of simple sugars. Carbohydrates are reactive b/c of the functional groups:carbonyl ( c=0) & hydroxyl ( oh) Glucose & galactose are different b/c of orientation, not makeup (makeup is same) 5&6 carbon sugars have rings, 3 carbon dont. Condensation reaction to hook monomers together when building a. Polymer, also when 2 monosaccharides to create a disaccharide. Sugar chains attached to proteins (glycoproteins) or lipids (glycolipids) help your immune system tell you apart from antigens. (transplants) Glycoproteins allow sperm to recognize and bind to eggs during sexual reproduction.
