It is a precursor in the synthesis of various amino acids, such as alanine, and of malic acid and oxaloacetic acid, both intermediates in the KREBS CYCLE.

Besides, the optimal dose of WLP is exactly 18 gramme per day, and too much intake of WLP will add to the risks of pushing up glutamic-oxaloacetic transaminase(AST) index in body.

Objective To evaluate the significance of elevated serum glutamic oxaloacetic transaminase(AST) and serum glutamic pyruvic transaminase(ALT) levels with intra-abdominal injury in children.
