Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
Inside protein molecule
Flavin adenine dinucleotide, FAD molecule.  Essential redox-active coenzyme involved in energy production and metabolism. Molecular model. 3D rendering. Illustration
What micro plastic is made of - Chemical ingredients.\nClose up of microplastic on finger concept of water pollution and global warming
3D cartoon and Gaussian surface models, PDB 6gu2, white background
A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.
The integration of fluidics and optics, antibodies molecule in flow-through nanohole arrays, has enabled increased transport of analytes to sensing surfaces 3d rendering
Freshness capsule
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
Close up of microplastic on female finger concept of water plastic pollution and global warming with text explaining the ingredients of micro plastic
B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, white background
3D rendering of cartoon hands with icons
Filtration and water purification scheme contaminated molecules pass through filter layers
A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
Folic acid, folate molecule. It is known as vitamin B9. Molecular model. 3D rendering. Illustration
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.
TNF-alfa (blue) is the most potent proinflammatory cytokine and is crucial in the pathogenesis of PsA. TNF-  inhibitors considerably relieve symptons in patients. A therapeutic antibody (adalimumab) blocks the receptor binding site of  TNF-.
Molecular model of Adenosine triphosphate,  or Adenosine-5'-triphosphate (ATP)
3D cartoon and molecular surface models, chain id color scheme, putative membrane shown, pdb 1l7v, white background
young woman, maybe chemist, businesswoman or teacher shows a molecular structure on a virtual whiteboard. Need more stuff like this:
Organic Carnauba Wax in Chemical Watch Glass with molecular structure place next to beaker and \nPlatycerium stemaria fern. Chemical ingredient used in cosmetic industry.
Open capsule or pill with molecular structure. Nanotechnology concept
Acetyl-CoA, acetyl coenzyme A molecule. Key coenzyme in fatty acid biosynthesis, Krebs cycle, citric acid cycle. Molecular model. 3D rendering. Illustration
A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.
