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.

Frataxin (human) mitochondrial protein. Reduced expression causes Friedreich's ataxia. 3D illustration. Cartoon & wireframe representation.

$The three-dimensional structure of proteins is represented in a variety of conformations. This image is based on the ribbon structure of a protein. It is suitable for biology notebooks and book covers.\nThis image has not been created by AI.$

Recombinant human insulin. 3d cartoon model based on protein data bank

Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.

Anthrax lethal factor, molecular model. This enzyme is one of three protein components that form the anthrax toxin produced by the bacterium Bacillus anthracis. Lethal factor (LF) disrupts cellular signalling pathways in an infected cell, eventually leading to cell death. Anthrax most commonly affects cattle, sheep and goats, but can also infect humans.

Immunoglobulin G (IgG) - 3d rendered image. Microbiology illustration the structure of an antibody. The Y-shaped structure. IgG is the most common type of antibody.

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.

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.

PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.

Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.

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.

PETase (left) degrades polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.

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.
