Amino Acids, Peptides, and Proteins

There are 20 naturally occurring proteogenic amino acids; it is these amino acids that are combined together to form the polypeptide chains making up the many different peptides and proteins found across all living organisms. This module introduces amino acids, peptides, and proteins.

Topics include:

• Introduction to amino acids, peptides, and proteins
• Amino acids in protein synthesis
• The peptide bond and protein formation
• Protein secondary structure
• Protein tertiary structure and disulfide bridges
• Post-translational modification of proteins
