Although some enzymes are attached very tightly to their coenzymes, others can be parted easily; in either case, the parting almost always deactivates both partners. The first coenzyme was discovered by the English biochemist Sir Arthur Harden (1865-1940) around the turn of the nineteenth ...
Enzymes are finding increasing use for the production of agrochemicals, pharmaceuticals, and fine chemicals. They are almost always used in the immobilized form in order to simplify their removal from the product stream. In addition, immobilization often enhances the stability of the enzyme. ...

The enzymes used in both applications are almost always impure mixtures of active enzyme and other metabolites from the production strain, hence similar safety evaluation procedures for both are warranted. We propose that the primary consideration should be the safety of the production strain and that...
The process of extraction with hexane always provides the best returns. With more than 96% of oil recovered, these processes are almost perfect. Three important reasons can question the use of hexane: air pollutant; dangerousness; cost. These three aspects make the research around this issue ...

Enzymes are very efficient and specific catalyst proteins which react with 1 or few types of substrates in biochemical reactions and are responsible for bringing about almost all of the chemical reactions in living organisms. Enzymes speed up reactions by providing an alternative reaction pathway of ...
Almost all enzymes are proteins, comprised of amino acid chains, and they perform the critical task of lowering the activation energies of chemical reactions inside the cell. Enzymes do this by binding to the reactant molecules, and holding them in such a way as to make the chemical bond-...
aHe almost walks to scholl every day. 他每天几乎走到scholl。[translate] a纪律过于苛刻会使员工感到累。人们可能会觉得不满意并且他们累的时候就不能发挥出他们的个人潜力。久而久之,长期感到厌烦和累,影响工作,影响效率,同样导致业绩的下降。 The discipline too is harsh can make the staff to feel tired...
