Melanin Physiology: Melanin Absoprtion of UV Light and Internal Conversion to Heat

The video explains the importance of melanin in protecting skin DNA from UV light. It covers the mechanism of DNA mutation through thymine dimers and how melanin acts as a protective barrier. The structure of melanin, including its monomers, is discussed, along with its mechanism of action, which involves absorbing UV light and dissipating energy as heat to prevent DNA damage.

What are the potential consequences of DNA mutations caused by UV light exposure?

What is the role of melanocytes in the skin?

Discuss the concept of internal conversion in relation to melanin.

Why is it important for melanin to dissipate energy as heat rather than releasing a photon?
