What is found in a membrane?

phospholipid biolayer is the membrane it self. the protein is what gets stick in the membrane. protein In context of unit membrane, it consists of a fluid mosaic of phosphoplipid bilayer and proteins.

A phospholipid bilayer is made up of two layers of phospholipids with their non-polar tails facing away from the aqueous environment and polar heads towards the aqueous environment. They make up 40% of the membrane.

Proteins make up 60% of the membrane and are of two types:

1. Integral proteins

2. Peripheral proteins

There can also be presence of cholesterol molecules in the membrane in the hydrophobic region.
