Turnover number has two different meanings: In enzymology, turnover number (also termed kcat) is defined as the maximum number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration for enzymes with two or more active sites. For enzymes with a single active site, kcat is referred to as the catalytic constant. It can be calculated from the maximum r… trinnov room correctionWebbLactic acidosis is an established feature of diabetes and LDH plays a crucial role in conversion of pyruvate to lactate and reportedly, the levels of lactate are significantly high which is consistent with our observation on increased levels of LDH. ...
