Lipid molecules, if we observe them, they tend to show a property that is hydrophobic.
00:08
So they can be called as hydrophobic molecules, that is water -faring molecules.
00:15
So if we take the lipid molecules, so if we put them in a beaker containing water, they tend to form a missile -like structure and enclose within it.
00:29
So they will form a missile.
00:31
So this is a missile which will protect them from the surrounding water medium.
00:38
So they can form a missile or if i put them in a water and water level is here, they can form a thin layer above the water.
00:49
So this can be our lipid molecules.
00:52
So these are some of the arrangements that are shown by the lipids.
00:56
So if we take our biological membrane, that is the plasma membrane, it is made up of the phospholipids, phospholipids and proteins.
01:11
And here if we are seeing a phospholipid molecule, it has a phosphate head, phosphate head, which is not like the lipid molecules because this is hydrophilic.
01:25
This always faces towards the water.
01:29
To this we have there is attachment of fatty acid chain.
01:34
Faty acid, the tail region.
01:38
And this fatty acid is our hydrophobic region...
