Enzymes: Properties Composition Active site and Classification
Biocatalyst i.e., Enzymes are proteins that increase rate of biochemical reactions converting substrate into product.
Properties of enzymes
- As almost all Enzymes are proteins, their ability to catalyze reactions is attributable to their primary, secondary, tertiary, and quaternary structures
- Enzymes accelerate chemical reactions tremendously
- Highly specific with respect to their reactants
- Work at specific temperature, pH and substrate concentration
- Get denature at high temperature and extremes pH
- Generally do not change during the course of reaction
- Catalyze only thermodynamically possible reactions
- A small amount of enzyme is sufficient for a large change in the rate of reaction
- Don’t change the position of equilibrium and direction of the reaction
- Enhance rate of any chemical reaction by decreasing the activation energy barrier of reactants
- Usually act by forming a transient complex with the reactant, thus stabilizing the transition state
- Reactants of enzyme catalyzed reaction are called substrates
