Amino acids absorbed from the alimentary tract and in excess of metabolic requirements, together with those generated by the breakdown of body proteins, are broken down further in a process known as oxidative deamination:
$$\begin{array}{*{20}c} \text{R} & {} & \text{R} \\ | & {} & | \\ {\text{NH}_\text{2} \text{CHCOOH + 1/2o}_\text{2} } & \rightleftharpoons & {\text{0 = CCOOH + NH}_\text{3} } \\ {\text{amino acid}} & {} & {\text{keto acid}\;\text{ammonia}} \\ \end{array}$$
