Content of the notes – 

• Peptides are chains of amino acids

• Peptides can be distinguished by their ionization behaviour

• Biologically active peptides and polypeptides

• Simple protein and conjugated proteins

• Primary structure of protein

• The function of protein depends on its amino acid sequence

• Overview of protein structure

• Proteins confirmation is stabilized largely by weak interaction

• Peptide bond

• Protein secondary structure

• Alpha and beta confirmation

• Protein tertiary and quarternary structure
