What is the Difference Between Denatured and Undenatured Protein?
🆚 Go to Comparative Table 🆚The difference between denatured and undenatured protein lies in their structure and function.
- Denatured Protein: Denatured proteins have undergone a change in their folding pattern due to external factors such as heat or chemical reactions, causing them to lose their original function. They have been altered from their natural state and may have been processed to remove beneficial fats and fatty acids. Denatured proteins are no longer considered functional in the same way as undenatured proteins. Examples of denatured proteins include cooked steak and whey protein that has been heated or processed to make it easier to digest.
- Undenatured Protein: Undenatured proteins are pure, properly functioning proteins without any structural deformation, intact with all bioavailable nutrients and constituents. They can perform their functions properly and are preferred for those sensitive to heat and acid-denaturing treatments. Undenatured proteins are made by applying minimal heat and no acid-based denaturing treatments.
In summary, denatured proteins have been altered from their natural state and have lost some of their original functions, while undenatured proteins maintain their proper structure and function. Undenatured proteins are generally preferred for consumption due to their purity and ability to perform their intended functions.
Comparative Table: Denatured vs Undenatured Protein
The main difference between denatured and undenatured proteins lies in their structural integrity and functionality. Here is a comparison table highlighting the key differences:
| Feature | Denatured Protein | Undenatured Protein |
|---|---|---|
| Structure | Loss of secondary, tertiary, or quaternary structures | Properly functioning structure without any deformation |
| Functionality | Loss of proper functioning due to structural changes | Can perform their functions properly |
| Denaturation | Occurs due to external stresses, such as changes in temperature or chemical reactions | Not affected by denaturation factors, maintains its original shape and function |
Denatured proteins have undergone a structural change, such as unfolding, that alters their original shape and function. In contrast, undenatured proteins are pure, properly functioning proteins without any structural deformation, intact with all bioavailable nutrients and constituents. It is essential to note that undenatured proteins are not necessarily better than denatured proteins; they are simply different.
