Select the products formed from the forward reaction of AST.

In the forward reaction of aspartate aminotransferase (AST), the enzyme catalyzes the transfer of an amino group from aspartate to α-ketoglutarate, resulting in the production of oxaloacetate and glutamate. This reaction is a key step in amino acid metabolism and is particularly important in the urea cycle and the synthesis of other amino acids.

Oxaloacetate is a four-carbon compound that plays a crucial role in the citric acid cycle, while glutamate is an important amino acid involved in various biosynthetic pathways and neurotransmission. The formation of these two products indicates the transamination process that AST catalyzes, effectively linking amino acid metabolism with energy production.

The other options do not accurately represent the products of the reaction catalyzed by AST. Thus, the correct selection highlights the important biochemical relationship between amino acid metabolism and the citric acid cycle.
