Document Summary
Draw and label structure of glucose including stereochemistry. How to convert fischer projection to haworth perspective. Structural properties of starch, glycogen, cellulose, chitin, agarose, and peptidoglycan. Mechanism of action for beta-lactam antibiotics such as penicillin. Carbohydrates: abundant and essential to virtually all living organisms: most abundant biomolecules on earth, monosaccharides: colorless crystalline solids, freely soluble in water. Most taste sweet: polysaccharides: used for energy storage and structure. Monosaccharides: characterized by number of carbons and if they are aldehydes or ketones. In open chain form: one carbon linked to carbonyl. Stereochemistry of linkage results in either alpha/beta stereoisomer. Polysaccharides: monosaccharides condense to form disaccharides, ex: maltose is 2 glucose molecules linked by alpha 1,4 bond (alcohol from. Some of the 3,6-anhydrogalactose have sulfate ester or pyruvate at c2: contained in cell walls of algae, polymers form double helices that aggregate and crosslink together.
