Document Summary
Nucleic acids chapter 3 (part 1 and 2) Carbohydrates chapter 8 (part 1 and 2) Lipids chapter 9 (part 1 and 2) All pyrimidines are attached via n1 to the sugar (either deoxyribose or ribose) Both purines are attached via n9 to sugar. Steric constraints hinder rotation about the glycosylic bond. 1st conformation the two oxygens repel each other sterically rotates base around allows for base pairing in dna. All the h-bonds are linear maximal strength. Often found covalently linked to proteins; glycoproteins have a profound effect on. Sugars polysaccharides proteins, their abilities to fold, their functions, etc. Glycosidic bond at anomeric atom, can be a source of energy. Unsaturation makes it hard to pack fatty acids together. Unsaturation makes membranes more fluid, being less packed together. Organisms use a range of saturated and unsaturated fatty acids to control the fluidity of the supramolecular lipid structures.
