Study Notes

Introduction to Enzymes

Enzymes function as biological catalysts, enhancing the rate of chemical reactions without undergoing any permanent change themselves.
They are crucial for facilitating almost all chemical reactions necessary for maintaining animal homeostasis.
Enzyme concentrations in cells are typically much higher than in plasma, allowing for effective physiological function.
Measurement of enzyme levels in plasma can indicate tissue damage, as enzymes may leak into the bloodstream from injured cells.
The evaluation of enzyme activity is vital for clinical diagnosis, helping to identify organ dysfunction or disease.
Pharmacological regulation of enzymes plays a significant role in therapeutic approaches to treat various health conditions.
Most enzymes are protein-based macromolecules, emphasizing the connection between enzyme activity and protein structure.
Clinical enzymology focuses on quantifying enzyme activity to aid in disease diagnosis and management.
