Peptide Bond

Bond that joins together amine (NH2) end and a carboxyl (COOH) end

Primary Structure

First stage of protein structure

  • sequence of amino acids

New cards

Secondary Structure

Second Stage of protein structure

  • slight folding, beginning of modification

    • Hydrogen bonds form alpha-helices (twists) and beta-pleated sheets (folds)
