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.

Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. 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.
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.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.
Afamelanotide is a synthetic peptide stimulating hormone used to prevent skin damage from the sun. 3d illustration
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
Lysozyme, the natural antibacterial enzyme contained in saliva, milk, mucus, tears, egg white and so on

A 3D rendering of a SpyTag-SpyCatcher conjugate, the molecular interaction between these biomolecules. This is used in various biotechnological applications for protein labeling and purification.
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.
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.
Background created by fractal geometry.
The amyloid beta peptide (light blue) is a component of the amyloid precursor protein, which is bound to a cell membrane. The gamma secretase enzyme cuts the free form, that aggregates to amyloid plaques. Source: PDB entries 2beg, 1mwp
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.

Molecular Model of Cyclosporine, an immunosuppressant drug widely used in organ transplantation to prevent rejection.
3D rendering of biotinylated antibody, an engineered protein designed to bind to specific molecules. Biotin allows researchers to easily track and manipulate these antibodies.
Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=phosphorus
RAGE (Advanced glycosylation end product-specific receptor) belongs to the immunoglobulin superfamily and is involved in diabetes, Alzheimer's disease, inflammation and tumour invasion. The conformations of the transmembrane and intracellular domains are assumed
A molecular model of Amyloid protein fibrils. Formed when mis-folded proteins self-assemble into fibrous sheet structures, they are found in the brains of sufferers of Alzheimer's disease and may be implicated in causing the disease.
