A ball and stick model of a molecule of Human Glucagon, a hormone produced in the pancreas and used by the body to raise levels of glucose in the blood. Glucagon worksin the opposite manner to Insulin, which lowers levels of glucose in the blood - together they work to keep glucose levels stable.
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.

ATP Synthase Protein - 3d rendered image. Medical microbiology concept.  Structure and conformational states of the bovine mitochondrial ATP (Adenosine triphosphate) synthase. Chemical energy is synthesized in eukaryotic cells primarily. Hydrolase. Hologram view. HUD, FUI
Recombinant human insulin. 3d cartoon model based on protein data bank
Molecular Model of Cyclosporine, an immunosuppressant drug widely used in organ transplantation to prevent rejection.
3d rendering of ubiquitin is attached to target proteins by a process called ubiquitination
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.
A ball-and-stick plus ribbons 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.
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
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.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Calmodulin is an intracellular target of calcium ions. Once activated by Ca2+ (red), calmodulin interacts with various target proteins such as kinases and phosphatases. It plays an important role in long-term memory and muscle contraction. CaM has 4 calcium binding sites. PDB entry 3CLN
Cell Membrane Phospholipid Structure,Phospholipid bilayer of the cell membrane,Lipid bilayer,lipid bi-layer cell anatomy
3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D 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.
C-reactive protein (CRP), an annular (ring-shaped), protein found in blood plasma. It is thought to assist in complement binding to foreign and damaged cells and enhances phagocytosis by macrophages.
Computer generated 3D abstract forms.\n\nNote: This image is less than one year old, and is  not available for use anywhere else. I created it on Blender 3.0.1,  and that is the reason it has no EXIF data. I uploaded in a property release section a screenshot of processing the composition on Blender on my PC. Date of creation is 01/11/2022.
Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation combined with semi-transparent surfaces.
Abstract geometric shape
3D cartoon model, secondary structure color scheme, PDB 2ygt, white background
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.
The amyloid beta peptide is a component of the amyloid precursor protein, which is normally bound to a cell membrane. The gamma secretase enzyme cuts the free form out, that aggregates to amyloid plaques.
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.
