🎈 Big Idea: Just as diverse Lego pieces can build a variety of fun structures, the chemical diversity in amino acids' R-groups allows for the creation of a vast array of proteins, each with a unique function! 🎈

🌈 The magical 20 amino acids

  • All proteins in our body start off with a set of 20 different amino acids.
  • Think of these like the 20 different ingredients in a master chef's kitchen, ready to create countless dishes.

🎨 The art of the R-groups

  • Each amino acid has a unique "R-group."
  • R-groups are like the unique flavors in each ingredient that determine the taste of the dish.
  • Table 2 (not shown here) lists the elements present in these R-groups.

🔗 The chain connection

  • Amino acids connect to form a chain called a polypeptide.
  • How? The amine group (–NH2) of one amino acid links with the carboxyl group (–COOH) of another. Think of this like linking two paperclips together.
  • Fun fact: This leaves one free amine group at one end and a free carboxyl group at the other end. It’s like having two different types of pendants on each end of a necklace.
