how Plasma membrane farmed

The term cell membrane was given by C. Nagili 

Chemical composition

Cellular membrane contain protein lipid, carbohydrates different rcio In different living being

Structure of plasmamembrane 

There are three models which explains structure of plasmamembrane 

1-bio membrane model 

(1935 Daniel and division )

2-United membrane model

(1959 Rabertson )

3-fluid mosaic model

 (1972 Ringer and nicolson)

           Bio membrane model

This model explain a lipid bylear was contain with globular protein on its ither side lipid chain attracted with protein  leayer by electrostatic force of attraction that attraction meantain the stability of a membrane that daniall and davision protected the lipid by leayer about 6.0nm in thickness and the protein leayer about 1.0nm in thickness the totel thickness of membrane is about 7.5nm.

Unit membrane model

This hypothesis state that all cellular membrane have on identical trilaminor structure.

flud mosaic model

According to thish model plasma membrane contain by molecular lipid leayer . both surface intrepid by protein asked in globular fom and drited hear and there . Some protein are attached at the produce surface of the light called extrinsic protein on these cell intrinsic protein at the lipid surface attached two suger cell glycoproteins and lipid attached with sugar cell glycolipid

glycoproteins and glycolipid combaing cell glycocomlex an account fluidity and mosaic arrangment of protein . this model know as fluid mosaic model .
