What is melanosome?

Melanosome is a type of organelle inside the cell. Organelles are specialized parts of cells that have specific functions; Orighelles behave in cells similar to organs in the body. To be called melanosome, it must contain something called melanin. Melanin is a natural pigment found in both humans and animals; It gives the living organism its natural color. For example, a person who has a darker skin tone has more melanin, while people with lighter skin have less melanin. Orighelles are often compared with organs in the human or animal body. The body has organs that have important functions for maintaining it alive and functioning. The same arrangement applies to cells. Orighelles are like small organs that play a role in the life and function of cells.

There are different types of organelles, but those that contain melanin are called melanosomes. The presence of melanosomes actually affects what is called a cell. If the cell contains melanosomes, it is called melanocyte. Melanocytes produce melanin that not only gives the skinIts color, but also helps determine the color of the eyes and hair of a person.

Melanin does not only affect the appearance of a person. It also affects human vulnerability to skin damage caused by exposure to ultraviolet rays from the Sun. Individuals with a higher amount of melanin are usually less vulnerable than those with smaller ones. Light people tend to be more vulnerable, which means that it is more likely to develop sun and skin cancer. However, no one is immune to sun effects, no matter how much melanin it has in its skin.

The

process of melanin production begins when deoxyribonucleic acid (DNA) sends melanocyte instructions that stimulate it to create enzymes capable of producing melanin. Melanocyte also creates amino acid, an organic compound that helps to build a protein called tyrosine as part of the process. Melanosomes take enzymes and amino acid and begin the process of transforming tyrosineto melanin. The role of enzymes is to act as catalysts and initiate the process of chemical reactions necessary for melanin production.

Melanosome can move a bit in some types of animal cells, such as those found in some reptile species. This explains the ability that some reptiles must mask or change color if necessary. In this case, changes in hormonal or nerves of mobility of melanosomes and lead to changes in color.
