Did you know that histidine is the only amino acid with a side chain that has a pKa close to physiological pH, enabling it to exist in both protonated and deprotonated states at a neutral pH? This unique characteristic is why histidine is special and so functionally versatile in biological systems.

Approximately 20% of the oxygen we breathe is converted into reactive oxygen species, making antioxidant activity crucial for cellular defense. This process involves complex chemical mechanisms where specific compounds protect the body by combating oxidative damage and inhibiting chain reactions.

With over 8,000 different types identified, polyphenols are abundant plant compounds known for numerous health benefits. A key function is their potent antioxidant activity, and understanding the precise mechanism of action of polyphenols as antioxidants is crucial for appreciating their protective effects.

Polyphenols are a vast group of over 8,000 phytochemicals, and their diverse chemical structures lead to a wide array of reactions. Understanding what are the reactions of polyphenols is crucial for their utilization in food, nutrition, and health, as these reactions can influence color, flavor, and antioxidant capacity.
