3D cartoon and Gaussian surface models, PDB 6vg8, white background
A ball-and-stick 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.
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
DNA A-T Pair
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
Rendered Remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of 2019-nCoV in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, based on the chemical structure available in public space from U.S. National Library of Medicine, which was professionally checked. Color symbols - green=carbon, red=oxygen, blue=nitrogen, white=hydrogen, purple=phosphorus

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.
Spherical molecule render. The model is isolated on white and could be easily extracted as well as used with the background.
Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration
Close-up of DNA molecule, with very selective focus. The model is scientifically correct, featuring different geometric shapes with labels.
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
A space-filling molecular model of collagen, a fibrous protein that provides structural support in animals. It has a distinctive triple helix structure. Isolated on black.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Molecular model of tyrosine, one of 20 required amino acid to form proteins.
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.
3d structure of l-glucose molecule.
Remdesivir is a broad-spectrum antiviral medication, it is a specific treatment for COVID-19. 3d illustration
Computer-rendered drug molecule hydroxychloroquine, which showed efficacy to treat COVID-19 patients and was mentioned by President Trump at White House briefing. Color symbols - red=oxygen, blue=nitrogen, white=hydrogen, green-chlorine.
3D cartoon and Gaussian surface models, PDB 4cmh, white background
A space-filling model of Human Growth Hormone, also known as Somatotropin.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Model of human Insulin, a hormone to regulate carbohydrate and fat metabolism
