3D realistically coloured hexagonal shapes of connected spheres, background with copy space. Futuristic illustration design template for scientific presentation. Molecular business, science, teamwork concept.
A new antibiotic (zosurabalpin, red) traps lipopolysaccharide (orange) in the intermembrane transporter of the Gram-negative bacterium Acinetobacter baylyi
Molecular model of lactose, a disaccharide sugar in milk.
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
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.
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.

3D cartoon and Gaussian surface models. PDB 1qxm, white background.
Organic objects form a triangle. Artificial space incorporating organic materials.\nThis work was policy within one month. It is also an original work for this brief and cannot be used elsewhere.
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.
DNA A-T Pair
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
