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.
Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.
PETase is a bacterial enzyme that breaks down PET-plastic to monomeric molecules. The whole bacterial degradation process yields terephtalic acid and ethylene glycol, which are environmentally harmless.
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.

Alpha-tubulin 3C, a protein associated with the genetic diseases Clouston hidrotic ectodermal dysplasia and Kabuki syndrome. 3d rendering.
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.
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.

Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
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.
3D cartoon model, secondary structure color scheme, PDB 2rfn, white background
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.
Rapamycin, also known as sirolimus is a macrolide compound that has immunosuppressant functions and prevents transplant rejection through the inhibition of  the protein complex mTORC1.
Natural abstract fluid art painting in alcohol ink technique. Soft dreamy colors create transparent wavy lines.
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.
