Question

The primary structure of which enzyme was discovered first?

• A. Trypsin
• B. Rnase A
• C. Lysozyme
• D. Carboxypeptidase

Hint:

Lysozyme's discovery helped in understanding the relationship between the primary structure of proteins and their biological functions, marking a major milestone in biochemistry.

Answer 1

The Correct Option is C

The primary structure of an enzyme refers to the linear sequence of amino acids in a protein. The first enzyme for which the primary structure was determined is Lysozyme. Lysozyme, an enzyme that protects the body from infection by breaking down bacterial cell walls, was the subject of structural studies that led to the determination of its amino acid sequence. This marked a significant milestone in biochemistry, illustrating the importance of understanding protein structures for insights into their functions and mechanisms.
