Melanin is not a hormone. It is a pigment that gives color to skin, hair, and eyes. Melanin is a complex polymer derived from the amino acid tyrosine. It is produced in specialized cells called melanocytes.
While melanin is not a hormone, there are several hormones related to its production and function. For example, melanin-concentrating hormone (MCH) is a hormone that influences skin pigmentation and other functions.
Here are some examples of the different types of melanin and their functions:
- Eumelanin: This type of melanin is responsible for brown and black pigment.
- Pheomelanin: This type of melanin is responsible for red and yellow pigment.
It is important to note the difference between melanin and melatonin. Melatonin is a hormone that regulates sleep cycles, while melanin is a pigment that gives color to skin, hair, and eyes.
