  5. Carbon-carbon bonds
  1. They do not have a tertiary structure.
  2. Their structures cannot be predicted from their primary amino acid sequences.
  3. Hydrogen bonds between carboxyl groups help stabilize their structures above the primary level.
  4. Their alpha-helix and beta-strand sequences have the same proportions of amino acids.
  5. Their structures may show forward and reverse turns.
  1. Glycine
  2. Alanine
  3. Glutamic acid
  4. Valine
  5. Isoleucine
  1. There are 4 structures used to describe the secondary structure of proteins.
  2. Alpha helixes and beta-strands were discovered by Linus Pauling.
  3. In alpha-helixes, hydrogen bonds are formed between carboxyl oxygen and the amine hydrogen.
  4. Beta-sheets are groups of beta-strands from different parts of a protein.
  5. Proline and glycine are frequently found in reverse turns.
