BIL 150 Lecture Notes - Lecture 5: Rhodopsin, Glycogen, Starch
Document Summary
Length, double bond position, branching, presence of rings. Geometric: different arrangement of atoms about double bond. R and s refers to whole molecule configuration. Glycogen: multi branched polymer (very branched starch) Humans store glycogen, use to generate atp. Configuration: permanent geometry resulting from spatial arrangement of covalent bonds. Sold as racemic mixture, only s effective. Fix atoms in one plane-cannot freely rotate. Has to do with how molecule is interacting with specific environment. Only molecules with complimentary shapes can form weak bonds. Morphine has same shape as endorphin, can bind to same receptor. Made of glycerol + 3 fatty acids. Ester linkage: carbon single bonded to o and double bond to another o. We store/use fat because it allows us to carry less weight of fuel. Contain 1 glycerol, 2 fatty acids, po4, and an organic molecule. Molecular structure is extremely important to function. Structure relates to the orientation of covalent bonds in 3d space.
