WebFor an enzyme that has no active site cooperativity, the EC50 (we would say IC50) curve of the inhibitor (% inhibition versus inhibitor concentration) should have a Hill slope of 1. If the curve has a Hill slope that is very different from 1 (e.g. 0.5 or 2), it usually means there is a problem with the measurement, such as insolubility of the ... Webthe hill-slope (in metres); (ii) height range of the hill-slope (in metres). Shape The shape of a hill-slope is described by two attributes: (i) Hill-slope curvature.
