Catalysts that appear in Biology, and catalyze many biological reactions, particularly, in Metabolism

https://en.wikipedia.org/wiki/Enzyme

What do enzymes do? – How do enzymes work? – Influenza virus - tricks of a burglar

are macromolecular biological catalysts

Examples of enzymes

Triose phosphate isomerase (TIM). It takes a Triose phosphate (with a Phosphate group), into an Isomer of it.

• Protease

Mechanisms

Active site. 3D cleft or crevice with precisely defined arrangement of atoms. Part of the enzyme that specifically binds the substrate. Substrate binds via multiple Intermolecular forces

• Lock and key
• Induced fit
• Really, it's a combination of both

Active site is defined by its shape and the chemistry of the Amino acids that make it.

Function

• Stabilize transition states.
• Avoiding side reactions

Enzyme kinetics

Enzyme synthesis

Using Bacteria

Applications

• In Food industry, washing powders
• Bioremediation, to clean up Contamination
• Biomimetic catalysts
