Molecular Detergents...a brief view..

Molecular Detergent??
Detergents are the cleansing agent, act as surfactants, emulsifying agents used in many biological experiments, and if we add the molecular its only mean those synthetic surfactants or detergent that are generally use in the Biochemical experiments. They are polar compounds with hydrophilic and hydrophobic regions.

How does a surfactant work?
The hydrophobic end that is attracted to oil, grease, and dirt . And the hydrophilic part is attracted to water. The hydrophobic end of the molecule gets away from the water and the hydrophilic end stays next to the water. When dirt or grease is present (hydrophobic in nature) the surfactants surround it and form a small aggregate known as “Micelle” which helps in the dislodging of the grease or dirt from the boundary.

Properties of Detergents…
Detergents generally of have 2 properties… a. CMC ( critical micelle concentration). b. MMW ( micelle molecular weight).

Types….
Depending upon the charge of hydrophilic head group detergen…
