CHAPTER 24: Unit 16. Pathways of Amino Acids Synthesis

The none esstential amio acids are 9  and are produced in the body. They essentail amino acids are 11 and are taken into the body through diet.The sysnthesis of the none essential amino acids in the body follows the steps below:

Some amino acids are formed by the reverse reaction of transamination.

Furthermore, some amino acids are formed through the transamination of keto acids (oxaloacetate):

In addition, some amino acids are synthesized through different pathways as the figure below illustrates:
