title: Microcomputer analysis of hyperbolic and non-hyperbolic steady-state kinetics.
abstract: A BASIC computer program has been developed which has been used to show that bovine lens aldose reductase with NADPH as substrate follows a 1:1 function, while rabbit lens hexokinase has a rate equation of minimum degree 2:2, and bovine lens polyol dehydrogenase has a rate equation of minimum degree 1:2 with xylitol as substrate. The parameter estimates obtained are very close to those from the BMDP3R curvefitting program on an ICL 2980 mainframe computer, with identical conclusions as to the minimum degree of the rate equation. The computer program can be run on any microcomputer with high resolution graphics in less than 48 K of random access memory.
