BIO206H5 Lecture Notes - Lecture 4: Neutrophil, Phosphodiester Bond, Alpha And Beta Carbon
Document Summary
Pyrophosphate: breaking 2 high energy phosphates off for phosphodiester bond. Dna is a right handed-helix and genetic material. Functions are related to their unique structure & composition: 3d structure and chemical reactivity contribute to defining protein function, proteins are the most structurally complex molecules, what are proteins, linear, unbranched polymers of amino acids. Building blocks - amino acids: 20 different amino acids, central carbon (alpha carbon, amino group, carboxyl group, hydrogen, side chain (r group) One or more atoms: 4 different groups bonded to the tetrahedral c . : r-group in glycine is a hydrogen atom so it only has 3 chemical groups and does not form a mirror image of itself. Determine the nature of an amino acid; reactivity & solubility. Amino group and carboxyl group charge removed by peptide bond formation. Non polar amino acids are hydrophobic while polar molecules can form hydrogen bonds. Within polar group, there are electrically negative, positive and uncharged polar molecules.
