PPT-Minerals and trace elements

By Professor Dr Jamal Ahmed Abdel Barry The elements can be considered in 5 groups Includes C H O N and S It is the major components of body molecule these elements are obtained through the intake of water foods fats CHO and proteins.

As for melting, we can imagine two possibilities: equilibrium and fractional crystallization.. Equilibrium crystallization occurs when the total liquid and total solid remain in equilibrium throughout the crystallization. If we define . Not synthesized. . in human . body.
