Enzymes are protein molecules whose role is to catalyse and control the chemical reactions that take place in living organisms. They perform this role in ways that differ from reaction to reaction but, in every instance, catalysis proceeds through the formation of complexes between the enzyme and ...
Enzymes are biological catalysts, it has a strong role in specificity, and high catalytic efficiency, in normal temperature conditions and low concentrations of complex biochemical reactions. No enzyme, there is no organism all life activities. Enzyme production and enzyme engineering study of a tec ...

Enzymes versus catalysts: a question of scale? For many industrial processes, biological catalysis is more cost effective than chemical catalysis. But doubts over how easy enzymes are to use is hampering uptake, Andrew Turley reports from InformEx in San Francisco.(Infomex report)...
enzymes act as colloidal catalysts and combine with their substrates and other substances by adsorption, “so that the action of enzymes in general must be regarded as exerted by their surface”, and a large part of his book was devoted to the support of this view. In the present work ...
aNature's catalysts -- enzymes -- function highly selectively to accelerate the rate of chemical reactions in biological systems. Enzymes also can limit reactivity toward a particular substrate and limit chemical conversion to a single desired product. 自然的催化剂 -- 酵素 -- 高度有选择性地加速化...
be bound to a non-protein coenzyme or metal ion cofactor. The size of enzymes can range from less than 100 to over 2500 amino acid residues [1]. Enzymes accelerate biochemical reactions by similar mechanisms to inorganic chemical catalysts (e.g., metals, metal oxides and metal ions), by ...
Catalysts, Biological biocatalysts, substances formedin living cells that accelerate (positive catalysis) or slow down(negative catalysis) the chemical processes in the body. Biologi-cal catalysts include primarily catalysts of a protein nature, theenzymes. ...
Biotechnology is present everywhere and it has had a great impact on several industrial sectors, such as fine chemical and pharmaceutical industry, textile, and detergent industries, biofuel generation, bioremediation, among others. Generally, industrial processes use chemical compounds as catalysts, genera...
