What are the 4 types of melanin?

The melanin pigments are produced in a specialized group of cells known as melanocytes. There are five basic types of melanin: eumelanin, pheomelanin, neuromelanin, allomelanin and pyomelanin. The most common type is eumelanin, of which there are two types— brown eumelanin and black eumelanin.

What are the benefits of melanin?

What are the benefits of melanin?

  • Protection against UV light. Melanin helps protect the cells of the epidermis, or outer layer of the skin, from UV light.
  • Reactive oxygen species (ROS) scavenger. Melanin also demonstrates antioxidant activity by scavenging for reactive oxygen species produced via UV light damage.

How does Dopaquinone become melanin?

It converts a protein building block (amino acid) called tyrosine to another compound called dopaquinone. A series of additional chemical reactions convert dopaquinone to melanin in the skin, hair follicles, the colored part of the eye (the iris), and the retina.

What color is melanin?

Genetics and evolution of hair and skin colour Melanin – a brown/black or red/yellow polymer produced by melanosomes in melanocyte cells.

What are the 2 types of melanin?

Types of Melanin

  • Eumelanin makes mostly dark colors in hair, eyes, and skin. There are two types of eumelanin: brown and black.
  • Pheomelanin colors the pinkish parts of your body like the lips and nipples.
  • Neuromelanin Controls the colors of neurons.

How do you stop tyrosinase?

Arbutin, a prodrug of hydroquinone, is a natural product and reduces or inhibits melanin synthesis by inhibiting tyrosinase.

Which organ produces melanin?

Special skin cells called melanocytes make melanin. Everyone has the same number of melanocytes, but some people make more melanin than others. If those cells make just a little bit of melanin, your hair, skin and the iris of your eyes can be very light.

Which food reduce melanin?

Many of these suppress tyrosinase, the main enzyme needed for melanin synthesis. This slows down melanin production and results in lighter skin. However, skin lightening products are known for causing side effects like: dryness.
