Do branched chain keto amino acids regulate their own metabolism?
Peter Schauder – 1 November 1988 – The effects of branched‐chain α‐ketoacids on flux through and activity state of the branched‐chain α‐ketoacid dehydrogenase complex were studied in hepatocytes prepared from chow‐fed, starved, and low‐protein‐diet‐fed rats. Very low concentrations of α‐ketoisocaproate caused a dramatic stimulation (50% activation at 20 μM) of α‐ketoisovalerate decarboxylation in hepatocytes from low‐protein‐fed rats. α‐Keto‐β‐methylvalerate was also effective, but less so than α‐ketoisocaproate.
