Question

Which of the following statement is correct

• A. \(\beta\)-lactoglobulin has 162 amino acids and contains 04 cysteine residues
• B. \(\alpha\)-lactalbumin has 123 amino acids and contains 08 cysteine residues
• C. Kappa-casein has 169 amino acids and has 02 cysteine residues
• D. \(\alpha\)-lactalbumin is the major whey protein in cow milk

Hint:

Remember that \(\kappa\)-casein contains 169 amino acids and 2 cysteine residues. Its cleavage by chymosin at the Phe(105)-Met(106) bond initiates milk coagulation.
