翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Katal ： ウィキペディア英語版 Katal The katal (symbol: kat) is the SI unit of catalytic activity. It is a derived SI unit for quantifying the catalytic activity of enzymes (measuring the enzymatic activity level in enzyme catalysis) and other catalysts. Its use is recommended by the ''General Conference on Weights and Measures'' and other international organizations. It replaces the non-SI ''enzyme unit''. Enzyme units are, however, still more commonly used than the katal in practice at present, especially in biochemistry. The katal is not used to express the rate of a reaction; that is expressed in units of concentration per second (or moles per liter per second). Rather, it is used to express ''catalytic activity'' which is a property of the catalyst. The katal is invariant of the measurement procedure, but the numerical quantity value is not and depends on the experimental conditions. Therefore, in order to define the quantity of a catalyst, the rate of conversion of a defined chemical reaction is specified as mols reacted per second. One katal of trypsin, for example, is that amount of trypsin which breaks a mole of peptide bonds per second under specified conditions. ==Definition== :1 kat = 1 mol/s 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Katal」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
