Notes on "Proteins"

.

TERMS TO KNOW
  • Proteins

    ​Organic molecules composed of amino acids.

  • Amino Acids

    ​The building blocks of proteins. Amino acids compose proteins.

  • Peptide Bond

    ​A type of bond that joins amino acids together.

  • ​Polypeptide Chain

    ​A chain formed when three or more amino acids join together.

  • Primary Structure of Proteins

    The most simple structure of proteins composed of a chain of amino acids.

  • ​​Secondary Structure of Proteins

    The second level of organization of proteins where amino acid chains twist and fold.

  • ​Tertiary Structure of Proteins

    ​The third level of organization of proteins where amino acids continue to twist and fold forming a 3-D shape.

  • ​Quaternary Structure of Proteins

    ​The most complex level of protein structure where the tertiary structure of several amino acid chains are bonded together.
