LIPID

LIPIDS

Lipids are organic compounds that are insoluble in water but can be extracted with non polar solvents such as chloroform, ether, benzene, alcohol, acetone, and karbondisulfid. These organic compounds are present in all cells and function as:

1. Energy storage and transport

2. Membrane structure

3. Leather protector, cell wall components

4. Chemical transmitter

Some lipid compounds have important biological activity in the body, including vitamins and hormones. Viewed from the angle of nutrients, fat is an important source of calories in addition to acting as a solvent in vitamins.  Lipids can be classified according to chemical and physical properties.

Protein

Protein is an organic compound of high molecular weight ranging from several thousand to millions. This protein is composed of atoms C, H, O and N and the other two elements such as P and S which form the amino acid units. These amino acids can be divided according to their chemical structure (aliphatic, aromatic, heterocyclic) or according to its R group.
