In chemistry, the term "turnover number" has two distinct meanings.. In enzymology, the turnover number (k cat) is defined as the limiting number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration [E T] for enzymes with two or more active sites. [1]
06-Oct-2009: In analyzing the actual performance of T:Convert in hundreds of articles during 2009, I have noticed that the template-creep for converting km to miles has reached 20-to-26 templates invoked for each conversion, depending on rounding. Instead, it is possible to convert km/miles with rounding, abbreviations, slashes, and adjective ...

Most enzymes have a rate around 10 5 s −1 M −1. The fastest enzymes in the dark box on the right (>10 8 s −1 M −1) are constrained by the diffusion limit. (Data adapted from reference [1]) A diffusion-limited enzyme catalyses a reaction so efficiently that the rate limiting step is that of substrate diffusion into the active site, or ...
Template documentation For the unit conversion template, see Template:Convert . Editors can experiment in this template's sandbox ( create | mirror ) and testcases ( create ) pages.
{{convert|100|lb|kg}} → 100 pounds (45 kg) The unit-codes should be treated as case-sensitive: {{convert|100|Mm|mm}} → 100 megametres (1.0 × 10 11 mm) The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination ...
Template talk:Convert/Archive 3#Crore; Template talk:Convert/Archive 3#Lakh and crore; I have not yet examined the RfC at WT:Manual of Style/Dates and numbers#RfC Indian numbering conventions. The above discussions point out that lakh and crore are not units. They are like million which is also not a unit. However, if convert could do something ...
The katal (symbol: kat) is that catalytic activity that will raise the rate of conversion by one mole per second in a specified assay system. [1] It is a unit of the International System of Units (SI) [1] used for quantifying the catalytic activity of enzymes (that is, measuring the enzymatic activity level in enzyme catalysis) and other catalysts.
