This means it functions inside the cell with a definite purpose just like an organ, such as a kidney, functions in a body. But melanocytes are regularly making brand new melanosomes. A melanosome is initially constructed of a fiber-like network foundation laid down by special protein (Pmel17) unique to melanocytes.
1 Joule = 0.239005736 Calories. Joule is metric system unit (electrical, mechanical or thermal) and defined as the amount of work done by a force of one newton to move an object one meter or a current of one ampere when passing through one ohm resistance for one second.
Although these units relate to the metric system all forms of the calorie were deemed obsolete in science after the SI system was adopted in the 1950s. The unit of energy in the International System of Units is the joule. One small calorie is approximately 4.2 joules (so one large calorie is about 4.2 kilojoules).
