Enzyme denaturation is normally linked to temperatures above a species' normal level; as a result, enzymes from bacteria living in volcanic environments such as hot springs are prized by industrial users for their ability to function at high temperatures, allowing enzyme-catalysed reactions to be operated at a very high rate.
Enzyme catalysis is the increase in the rate of a process by an "enzyme", a biological molecule. Most enzymes are proteins, and most such processes are chemical reactions. Most enzymes are proteins, and most such processes are chemical reactions.
The study of enzyme kinetics is important for two basic reasons. Firstly, it helps explain how enzymes work, and secondly, it helps predict how enzymes behave in living organisms. The kinetic constants defined above, K M and V max, are critical to attempts to understand how enzymes work together to control metabolism.
While this experiment certainly does a good job of showcasing one type of enzyme, there are more than 75,000 different enzymes that all benefit the body in different ways, says Whitney Holden, PhD ...
Depending on the substrate and enzyme involved, P450 enzymes can catalyze any of a wide variety of reactions. A hypothetical hydroxylation is illustrated. After the hydroxylated product has been released from the active site, the enzyme returns to its original state, with a water molecule returning to occupy the distal coordination position of ...
The enzymes lactase and sucrase, made in the small intestine, break down dairy sugar and sugar, respectively. Pepsin, made in the stomach, is the main enzyme involved in the digestion of protein.
Biosynthesis, i.e., chemical synthesis occurring in biological contexts, is a term most often referring to multi-step, enzyme-catalyzed processes where chemical substances absorbed as nutrients (or previously converted through biosynthesis) serve as enzyme substrates, with conversion by the living organism either into simpler or more complex ...
