  • Test for protein
    Add Biuret's reagent
    positive test= violet/mauve
  • What is the quaternary structure of a protein?
    The quaternary structure of a protein refers to the arrangement of multiple protein chains (subunits) that come together to form a functional protein complex.
  • What is the tertiary structure of a protein?
    The tertiary structure of a protein is the overall three-dimensional shape of the protein, created by interactions between the side chains of amino acids.
  • What is the secondary structure of a protein?
    The secondary structure of a protein refers to the way the chain of amino acids folds or twists into shapes like alpha helices or beta sheets.
  • What is the primary structure of a protein?
    The primary structure of a protein is the sequence of amino acids in the protein chain.
  • What is a peptide bond?
    A peptide bond is a covalent bond that links two amino acids together.
  • What are the four levels of protein structure?
    Primary, secondary, tertiary, and quaternary
  • What is the structure of an amino acid?
    An amino acid has an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R group) attached to a central carbon atom
