Protein acts as buffer due to which propey
**Core Concept**
Proteins act as buffers due to their ability to accept or donate protons, thereby resisting changes in pH. This property is attributed to the presence of **amino acids** with ionizable groups. The **isoelectric point** of a protein is the pH at which it has no net charge.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general concept. Proteins can act as buffers due to the presence of **ionizable amino acids** such as histidine, aspartic acid, and glutamic acid. These amino acids can accept or donate protons, depending on the pH of the solution.

**Clinical Pearl / High-Yield Fact**
Proteins play a crucial role in maintaining **acid-base balance** in the body. Their buffering capacity helps to regulate pH levels in various tissues and fluids.
