Medical Biochemistry-I (MLT 101)
Important Topics
- Biomolecules: carbohydrates, proteins, lipids
- Enzymes: definition, classification (basic), factors affecting
- Vitamins & minerals (basic roles)
- Buffers and pH (intro)
- Clinical relevance: normal values idea (intro)
Quick Notes (Short Explanation)
Biochemistry focuses on body chemicals and how they work in health and disease. Biomolecules (carbs, proteins, lipids) provide energy, structure, and regulation. Enzymes speed up reactions; temperature and pH can increase or reduce activity. Buffers keep pH stable—important for enzyme function and blood balance.
Tip: Exam me mostly definitions + short notes + diagrams (simple pathways) ask hote hain.
