What's a protein? Proteins are polypeptides that have some biological function.

Concept #1: Peptides and Polypeptides

Concept #2: Standard Amino Acids

The 20 most common amino acids all share the following traits:

  • A. They are α-amino acids 
  • B. They have an L-(S)-configuration at the chiral carbon
