FAQs on Free Radicals: Properties and Formation Video Lecture - Organic Chemistry

1. What are free radicals?
Ans. Free radicals are highly reactive molecules that have an unpaired electron in their outermost shell. They are formed as a natural byproduct of various chemical reactions in the body and can also be generated by external factors such as pollution, smoking, or exposure to radiation.
2. How are free radicals formed?
Ans. Free radicals can be formed through a process called oxidation, where molecules lose electrons. This can occur during normal metabolic processes in the body, such as the conversion of food into energy. Additionally, external factors like exposure to UV radiation, pollution, or toxins can also lead to the formation of free radicals.
3. What are the properties of free radicals?
Ans. Free radicals are highly reactive and unstable due to the presence of the unpaired electron. They can react with other molecules in the body, such as DNA, proteins, and cell membranes, causing damage and potentially leading to various health problems. Free radicals are also capable of initiating chain reactions, where one free radical can generate multiple new free radicals.
4. How do free radicals affect the body?
Ans. When free radicals react with cellular components, they can cause oxidative stress, which is linked to various diseases such as cancer, cardiovascular diseases, and neurodegenerative disorders. Free radicals can damage DNA, leading to mutations and potentially causing cancer. They can also disrupt cell membranes and impair the function of proteins and enzymes.
5. How can we protect ourselves from free radicals?
Ans. Antioxidants play a crucial role in neutralizing free radicals and preventing oxidative damage. Eating a diet rich in fruits, vegetables, and whole grains can provide a good source of antioxidants. Additionally, avoiding exposure to environmental pollutants, quitting smoking, and minimizing sun exposure can also help reduce the formation of free radicals in the body.
