Wait just a minute! is this amoeba lipid or intra-alveolar surfactant? ha ha… I was googling liver toxicity and up came this article (from an image I selected to view the page) and i thought to myself… this could be intra-alveolar surfactant in the alveolar space (left) and tubular myelin in the alveolar space just organized in the center of the image on the right. This just goes to show us that some principles and some patterns of molecules and physics are going to show up in surprising places.
The article itself was on 3D representations of some molecular organizations in cells, it was interesting as well and linked here.
