About Hyaluronidase
- Also known as the 'spreading factor' — it increases tissue permeability by depolymerising hyaluronic acid in the extracellular matrix.
- Clinically used to enhance absorption and diffusion of injected drugs (e.g., local anaesthetics, subcutaneous fluids).
- Natural role: present in sperm acrosome — helps sperm penetrate the corona radiata and zona pellucida of the ovum.
By-product Enzymes from Animal Slaughter
- Hyaluronidase → Bull or Ram testes
- Rennet (Rennin/Chymosin) → Abomasum of suckling calf (used in cheese making)
- Pepsin → Mucosal lining of pig stomach
- Heparin → Cattle lungs (anticoagulant)
- Insulin → Pancreas of cattle/pig
