How Does Complete Melanin Biosynthesis Pathway | Eumelanin & Pheomelanin Work?

Melanin is like the paint that makes your skin, hair, and eyes unique, it comes in two types: eumelanin, which is dark like black or brown, and pheomelanin, which is lighter, like red or yellow.

How Melanin Is Made

Imagine you have a melanin factory inside your skin cells. This factory uses special ingredients, like tyrosine, a protein, to make melanin. The main steps are:

  • Tyrosine becomes dopa, then dopamine, and finally eumelanin if it keeps going through more steps.
  • If the factory makes some pheomelanin, it uses a different ingredient called cysteine, giving your hair or skin a reddish or yellow tone.

Eumelanin vs Pheomelanin

Think of eumelanin as charcoal, deep and rich, like the color of a forest floor. It’s what makes people have dark hair or skin.

Pheomelanin, on the other hand, is more like clay, soft and warm, like the color of sunlit sand. It gives red or blonde hair its special shine.

So your melanin factory decides how much of each type it makes, and that’s why everyone looks a little different!

Examples

  1. A child with very dark hair has a lot of eumelanin, while someone with red hair has more pheomelanin.
  2. Imagine melanin as paint; eumelanin is black and brown paint, while pheomelanin is red and yellow paint.
  3. Melanin is made in special cells called melanocytes, like tiny factories inside the skin.
