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.

Calories and Joules. In chemistry we measure heat using two different units: calories and joules. A calorie is defined as the amount of energy needed to raise the temperature of one gram of water one degree Celsius. The âcalorieâ you are most familiar with is used to measure the energy content of food. This âcalorieâ is actually a kilocalorie (1000 calories) and is written with a capital C to distinguish it from the calorie used in chemistry. The Calories listed for this candy bar are actually kilocalories. The other unit used to measure heat is the joule. The joule is the SI (System International) unit.
