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.
c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
DNA A-T Pair
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=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.
Colorful Molecules 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.
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
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
A ball and stick model of a molecule of gamma-Cyclodextrin. Composed of eight glucose sugar molecules bound into a ring structure, cyclodextrins are easily made from simple starch. The large ring can bind smaller molecules within it, making Cylodextrins useful in drug-delivery applications and also to clean up toxins (such as heavy metals) in the environment. Currently, gamma-Cyclodextrin is being considered as a structure which can bind to and hold carbon dioxide gas for carbon capture and storage as a way to manage the effect of excess carbon dioxide on the climate.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
20 standard amino acids, from left to right they are: glycine, alanine, cysteine, proline, valine, serine, threonine, leucine, isoleucine, aspartic acid, asparagine, glutamic acid, glutamine, methionine, lysine, histidine, arginine, phenylalanine, tyrosine, and tryptophan
Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration
3d structure of l-glucose molecule.
Pyridoxal phosphate, PLP molecule. It is active form of vitamin B6 and coenzyme. Molecular model. 3D rendering. Illustration
Chemical science background
3D cartoon and Gaussian surface models, chain id color scheme, PDB 4ci9, white background
A ball and stick model of a molecule of Human Glucagon, a hormone produced in the pancreas and used by the body to raise levels of glucose in the blood. Glucagon worksin the opposite manner to Insulin, which lowers levels of glucose in the blood - together they work to keep glucose levels stable.
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.
molecular model of Sovaldi (generic name: Sofosbuvir), the most popular drug to treat hepatitis C infection
Maltose or maltobiose or malt sugar is a disaccharide formed from two units of glucose joined with an alpha bond. 3d illustration
