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.
Abstract geometric shape
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
DNA A-T Pair
3D rendering of biotinylated antibody, an engineered protein designed to bind to specific molecules. Biotin allows researchers to easily track and manipulate these antibodies.
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
3D cartoon and Gaussian surface models. PDB 2aai, white background.
A ball and stick + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
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.
Abstract geometric shape
Botulinum toxin neurotoxic protein, 3D rendering. Produced by Clostridium botulinum. Cosmetically used to treat wrinkles.

Beta-alanine or β-Alanine molecule. It is naturally occurring beta amino acid. Molecular model. 3D rendering. Illustration
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
3D cartoon and Gaussian surface models, chain id color scheme, PDB 5y0m, white background
A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.
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.
Colorful Molecules Background
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
\
Maltose or maltobiose or malt sugar is a disaccharide formed from two units of glucose joined with an alpha bond. 3d illustration
Scientific background. 3D render.
3D cartoon and Gaussian surface models, PDB 3hg3, white background
A ball and stick model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.
Abstract Pink And Green Knot
A molecule of sucrose, showing thermal ellipsoids.
Taq polymerase (Thermus aquaticus polymerase) enzyme bound to DNA, 3D rendering. Protein used in PCR (polymerase chain reaction).
Molecular Model of Vitamin E.
