Enzyme unit many kinds of substance besides enzymes (for example, vitamins and hormones). Enzyme unit The enzyme unit (symbol U or sometimes EU) is a unit for the amount of a particular enzyme. One U is defined as the amount of the enzyme that produces a certain amount of enzymatic activity, that is, the amount that catalyzes the conversion of 1 micro-mole of substrate per minute. The conditions also have to be specified: one usually takes a temperature of 25°C and the pH value and substrate concentration that yield the maximal substrate conversion rate. The enzyme unit was adopted by the International
Kavli Institute for the Physics and Mathematics of the Universe made of? What are its fundamental laws? Why do we exist?" The Institute for the Physics and Mathematics of the Universe was created in October 1, 2007, by its founding director Hitoshi Murayama and the University of Tokyo. It is funded by the Japanese Ministry of Science, as a part of their World Premier International Research Center Initiative. In 2012, the IPMU received an endowment from the Kavli Foundation and was renamed the Kavli Institute for the Physics and Mathematics of the Universe. Many notable scientists are employed at the IPMU. Among them: Kavli Institute for the Physics and Mathematics
