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.
A Joule, J, is the SI unit of energy and is defined as one kgÂ·m2/s2. The prefix kilo means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence per mole. calorie was originally defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius. One calorie = 4.184 J. One kcal = 1,000 cal. When we count calories in our food, we are actually referring to kilocalories; e.g. 1 dietary Calorie = 1,000 cal = 1 kcal.
