Which three amino acids cannot undergo transamination to an appreciable extent,making provision of their alpha-keto acids ineffective in lowering blood nitrogen concentrations in kidney disease patients?

Question

Quizplus · Accepted Answer

Lysine and threonine are the two amino acids that cannot undergo transamination because they lack a free alpha-keto group that can be transferred. Histidine, although it can undergo transamination, is also considered in this context due to its limited ability to do so effectively compared to other amino acids. This makes the provision of their alpha-keto acids ineffective in strategies aimed at lowering blood nitrogen concentrations in kidney disease patients, where the goal is to reduce the levels of amino acids that can't be easily converted.
