Give examples of derived proteins?

These are proteins formed when simple or conjugated proteins undergo partial or complete hydrolysis. Hydrolysis can be caused by acids, enzymes, or alkalis. Since they are formed as derivatives of proteins, they are called derived proteins.

During hydrolysis, proteins gradually break down into simpler intermediates, reducing their complexity step by step. In fact, protein digestion itself occurs through hydrolysis.

Derived proteins are classified into two types based on structural changes:

1. Primary Derived Proteins
   • Formed by slight changes in structure and properties of proteins.
   • Little or no breakdown of peptide bonds occurs.
   • Examples: Fibrin (from fibrinogen), Myosan (from myosin).
2. Secondary Derived Proteins
   • Formed by more extensive changes in structure and properties.
   • Peptide bonds undergo progressive hydrolytic cleavage.
   • Examples: Proteoses and Peptones.
