A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.

Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration

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

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

organic chemistry, model of the protein molecule - illustration of a biological particle

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

A carboxypeptidase is a protease enzyme that hydrolyzes a peptide bond at the carboxy-terminal end of a protein or peptide. 3D cartoon model, secondary structure color scheme, PDB 2v77, white background.

3D Rendering of Liquid Paint Splash on Black Background

Anthrax oedema factor. Molecular model of oedema factor (EF) from the anthrax bacterium Bacillus antracis complexed with a calmodulin protein molecule. EF is one of three protein components that form the anthrax toxin. It is an enzyme that interferes with water homeostasis, leading to the accumulation of fluid in the tissues. Anthrax most commonly affects cattle, sheep and goats, but can also infect humans.

Concept of Communication through Artificial Intelligence technology

A ball and stick + ribbons model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.

Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.

Enzyme Catalase, a very important antioxidant in organism

$Computer generated 3D abstract forms.\n\nNote: This image is less than one year old, and is not available for use anywhere else. I created it on Blender 3.0.1, and that is the reason it has no EXIF data. I uploaded in a property release section a screenshot of processing the composition on Blender on my PC. Date of creation is 01/11/2022.$

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.

$Organic objects form a triangle. Artificial space incorporating organic materials.\nThis work was policy within one month. It is also an original work for this brief and cannot be used elsewhere.$

3D model of a protein molecule. Endothelial tyrosine kinase receptor, a marker of angiogenesis.

$Background created by fractal geometry.$

Taq polymerase (Thermus aquaticus polymerase) enzyme bound to DNA, 3D rendering. Protein used in PCR (polymerase chain reaction).

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.

3D cartoon model, secondary structure color scheme, PDB 3r4s, white background

Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.

Molecular Model of Cyclosporine, an immunosuppressant drug widely used in organ transplantation to prevent rejection.

A molecule of sucrose, showing thermal ellipsoids.

Bovine beta-lactoglobulin protein, 3D structure. Major whey protein, present in cow milk. Important food allergen.

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.
