Document Summary
Most of the test comprised of lectures 3-10. Nonpolar - c"s and h"s on r-group; van der waals interactions. Always attaches to a carbon, c=o without nitrogen. C=o bonded to n is a peptide bond. Proteins can misfold and can cause sickle cell, background of sickle cell. Glutamine to valine on hemoglobin for sickle cell. Isomers and anomers, right handed living organisms. Recognize orientation of oh group on carbon one that dictates alpha or beta. Know cellulose is for plants and starch(plants) and glycogen(for animals) Unsaturated - cis 1 carbon to carbon doube bond, lower melting point to saturated. Structure of glycerides, fatty acids, phospholipids, steroids. Know trans fats - chemically hydrogenating it, causes higher melting point, interferes absorption of good fats. Rna - single stranded* (diff from dna) Debating whether proteins or nucleic acids were hereditary material. Know full name of dna and rna. Dna is more stable than rna which is why it replaced rna at the time.
