3D cartoon and Gaussian surface models. chain id color scheme, PDB 5zjd, 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.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Abstract geometric shape
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.

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.
Fictitious molecule model inside red and blue pill isolated on white.
3D cartoon and Gaussian surface models, PDB 6vg8, white background
A ball and stick + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
Abstract geometric shape
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.

Organic shape 3d virus model isolated on black background, medical 3d rendering illustration
Spherical molecule render. The model is isolated on white and could be easily extracted as well as used with the background.
3D cartoon and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.
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
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
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.
Maltose or maltobiose or malt sugar is a disaccharide formed from two units of glucose joined with an alpha bond. 3d illustration
Molecular model of Adenosine triphosphate,  or Adenosine-5'-triphosphate (ATP)
