Document Summary

Biol bc1502 introduction to cell and molecular biology. Polymer of amino acids structural molecules. Enzymes catalyze chemical reactions: amino acids subunit / monomer of proteins. Polymerized into proteins via peptide bonds a. i. R = generic term for function group side chains a. ii. Chemical properties imparted to amino acids by different side chains: contribute to distinct properties/functions of proteins, critical to biological processes a. iii. Peptide is a polymer of amino acids. The 30 structure that"s critical for function: not necessarily the sequence but how they fold and what ends up close together after folding, primary structure. Amino acid structure: order for n c, secondary structure. Local structural pieces, twists + turns of amino acid near each other in 1st structure. Alpha helix: use backbone n + c=o to form bonds (hydrogen bonds, h of amine hydrogen with o of carbonyl three amino acids away.
