View Complete Answer & Explanation
Question (English)
Casein exists in milk in the form of:
- Calcium-caseinate-phosphate complex ✓ Correct
- Calcium-caseinate-chloride complex
- Calcium-chloride-phosphate complex
- Calcium-chloride-caseinate complex
Explanation:
Correct Answer: Calcium-caseinate-phosphate complex

Casein — Key Facts
- Constitutes about 80% of total milk protein
- Cow milk: 3% casein | Buffalo milk: 4.3% casein
- Responsible for the white colour and viscosity of milk
- Present in milk as a colloidal suspension
- Types: α-casein (αs-casein + K-casein), β-casein, γ-casein
Casein Subtypes
- αs-casein: Calcium-sensitive; precipitated by calcium ions
- K-casein: Calcium-insensitive; NOT precipitated by calcium ions; stabilizes the casein micelle
