Biochemistry Tutorial #1 - Peptides
The alpha amino acids polymerize, or bond, through the elimination of a water molecule. Polymers composed of two amino acid residues are known as dipeptides. Longer polymers are called oligopeptides (up to around 20 amino acids) or polypeptides (> 20 amino acids). Proteins can contain any number of amino acids linked together but each has a unique length (number of amino acids) and sequence (the identity and order of amino acids in the polymer).
In this excercise, you will identify amino acids, the amino and carboxy groups involved in the peptide bond, look at peptide bonds and oligopeptide structure and finally also examine disulfide bonds.
