Biochemistry
Biochemistry explores the chemical processes within living organisms, focusing on biomolecules like carbohydrates, proteins, and nucleic acids.
Biochemistry
Biochemistry is the study of chemical processes in living organisms. It bridges chemistry and biology.
Key Biomolecules
| Class | Monomer | Function | Example |
|---|---|---|---|
| Carbohydrates | Monosaccharides | Energy storage, structure | Glucose |
| Proteins | Amino acids | Catalysis, transport, signalling | Haemoglobin |
| Lipids | Fatty acids | Membranes, energy storage | Triglycerides |
| Nucleic acids | Nucleotides | Genetic information | DNA, RNA |
Glucose — The Energy Currency
Glucose (C₆H₁₂O₆) is the primary energy source for most cells. During cellular respiration, glucose is broken down to produce ATP:
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + energy (ATP)
Glucose exists in both open‑chain and cyclic forms, with the α‑ and β‑glucose cyclic isomers being particularly important in polysaccharide formation (starch, cellulose).
