Prions are misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals.
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
Cell Membrane Phospholipid Structure,Phospholipid bilayer of the cell membrane,Lipid bilayer
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
