Each diagram below represents what each of the Amino Acids looks like in chemical structure!

If you have never seen these types of diagrams before, they are easy to understand. Basically, just as the little stick figures we draw to represent people, these diagrams are kind of like stick figures as well, only representing amino acids. The letters you see in each, are symbols for the chemical elements. For example, O represents Oxygen, H represents hydreogen, C represents carbon, and so forth. All of the elements such as oxygen, carbon, etc., can be combined in many ways, and shapes in order to make all the important chemical components that we are made of.

If you have never seen these types of diagrams before, they are easy to understand. This group of chemicals we call refer to as amino acids are simply a group of structures which can be used as building blocks for proteins. Any of of the amino acids below can be connected to each other to form chains. These chains are called proteins, and serve us in many ways as we shall discuss.



CLICK on ANY of the individual amino acids to learn about them !

The 20 biologically active amino acids. There are more amino acids in nature. However, humans utilize only these 20. Amino acids can be bonded together forming a chain. This chain is referred to as a polypeptide (Greek. poly, many: peptide, the bond between the amino acids). A polypeptide is what we call a protein.
