Membrane Proteins: Integral vs Peripheral — NEET Biology
📚 Practice Concept📖 NCERT Source
Depending on the ease of extraction, membrane proteins can be classified as integral and peripheral. Peripheral proteins lie on the surface of membrane while the integral proteins are partially or totally buried in the membrane.

Shows peripheral proteins on the surface, integral proteins embedded in the membrane, sugar molecules attached to proteins, and cholesterol molecules within the phospholipid bilayer. The phospholipids are arranged with hydrophilic heads facing outward and hydrophobic tails inward. (Figure 8.4 Fluid mosaic model of plasma membrane)
