Biochemistry
Linked via "biological membranes"
Lipids and Membranes
Lipids encompass a heterogeneous group of hydrophobic molecules, including fatty acids, triglycerides, and steroids. Their defining characteristic is their insolubility in water, which drives the formation of biological membranes. Phospholipids, organized into bilayers, create a [semipermeable barrier](/entries… -

Partial Pressure
Linked via "biological membranes"
Partial Pressure and Gas Diffusion (Fick's First Law Modification)
The diffusion of gases through a medium, such as air or biological membranes, is fundamentally driven by gradients in partial pressure rather than total pressure differences. Fick's First Law of Diffusion, when applied to gases, relates the molar flux ($Ji$) of component $i$ to the partial pressure gradient ($\nabla Pi$):
