Final answer:
The liver synthesizes non-essential amino acids through a process called transamination.
Step-by-step explanation:
The liver produces non-essential amino acids through a process called transamination.
In this process, an amino group is transferred from one amino acid to a keto acid, resulting in the formation of a new amino acid.
The liver has enzymes, such as transaminases, that facilitate this reaction.
For example, the liver can produce alanine from pyruvate through transamination.
Pyruvate, a keto acid, accepts an amino group from an amino acid like glutamate, resulting in the conversion of pyruvate to alanine.
Summary: The liver synthesizes non-essential amino acids by transferring amino groups from one amino acid to a keto acid in a process called transamination.
