Ferritin is a protein that contains iron and is the primary form of iron stored inside of cells. 3D cartoon model, PDB 4y08, white background
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.
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
A ribbons model of Human Growth Hormone, also known as Somatotropin, with a translucent surface model.
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
DNA A-T Pair
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
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 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.
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.
Nirmatrelvir inhibits the 3C-like protease of the SARS-CoV 2 virus. The coronavirus 3CL hydrolase enzyme, also known as the main protease, is essential for the maturation of the virus.
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.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Molecular Model of Human Insulin with disulfide bonds shown.
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.
Freshness capsule
3D cartoon and Gaussian surface models, PDB 2zva, white background
This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.
Proteasomes are large molecular machines that degrade unneeded or damaged proteins that have been tagged with polyubiquitin.
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.
Bovine beta-lactoglobulin protein, 3D structure. Major whey protein, present in cow milk. Important food allergen.
Molecular Model of Human Insulin with disulfide bonds shown.
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.
Abstract geometric shape
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
3d structure of l-glucose molecule.
The prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3). The active site is the big cavity on the lower right side of the molecule
A ribbons model of an antibody, also known as immunoglobin. The immune system produces antibodies (using white blood cells) which then identify and attack viruses and bacteria.
Interleukin 13 (IL-13) cytokine protein. 3D illustration. Cartoon representation combined with semi-transparent surfaces.
Background created by fractal geometry.
