You can't make amino acids directly in Little Alchemy 2. The game doesn't have the specific elements or combinations to create them.

Amino acids are the building blocks of proteins, and Little Alchemy 2 focuses on more basic elements and combinations. While you can create some related items like:

* Life: You can create life from the combination of water and air.

* Protein: You can create protein by combining life and earth.

These are related to amino acids, but you cannot directly create the amino acids themselves.
