Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
Molecular Model of Human Insulin with disulfide bonds shown.
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.
3d structure of l-glucose molecule.
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
A molecule of sucrose, showing thermal ellipsoids.
A 3D rendering of a SpyTag-SpyCatcher complex with antibody molecule in the white background
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.
3D cartoon and Gaussian surface models, PDB 2e5d, white background
Molecular model of amylose
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D 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, which was professionally checked. Color symbols - light blue=carbon, red=oxygen, blue=nitrogen, white=hydrogen, green=phosphorus
Linagliptin or Tradjenta is a medication used to treat diabetes mellitus type 2. 3d illustration
The DNA tetrahedron is designed to be mechanically robust; it consists of rigid triangles of DNA helices covalently joined at the vertices
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.
3D cartoon and Gaussian surface models, PDB 1j7n, chain id color scheme, white background
Molecular Model of Human Insulin with disulfide bonds shown.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D 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
Pyridoxine molecule. It is form of vitamin B6. Molecular model. 3D rendering. Illustration
