Proteins

Cards (14)

  • Proteins make up greater than 50% of an organism's biomass
  • Most proteins end in "-lin"
  • Most enzymes end in "-ase"
  • Amino acids are the monomers of proteins
  • There are twenty different amino acids used to make proteins
  • Amino acids are comprised of a carboxyl end, amine end, alpha carbon, and r group
  • The Carboxyl end (COOH) acts as an acid because it can release a hydrogen ion
  • The Amine end (NH2) can act as a base by accepting a hydrogen ion
  • The Alpha carbon is the central carbon atom to which all of the other functional groups are attached
  • The R group is the only part that is different in the twenty different amino acids. They give amino acids their distinctive properties
  • Individual amino acids are bonded together by a covalent bond called a peptide bond
  • In order to create a peptide bond, the amino end of one amino acid is position to combine with the Carboxyl end of the second amino acid. The amino acids are joined during dehydration synthesis
  • Two amino acids bonded together are referred to as a dipeptide
  • A polypeptide chain is a long chain of amino acids joined together by peptide bonds
