Is it true that lipid-soluble substances diffuse directly through the phospholipid bilayer of cell membranes?

The claim that lipid-soluble and small passive molecules diffuse directly through the phospholipid bilayer is a fundamental biological principle supported by general scientific knowledge and membrane transport studies.

Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked 6 Aug 2026

The analysis

The claim is a standard, well-established biological fact regarding membrane permeability and simple diffusion. Although many retrieved papers deal with materials science, drug delivery, or specific nanoparticle/protein interactions, paper 6 supports the concept of passive transport directly through the phospholipid bilayer for water molecules.
