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.

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.
Model of human Insulin, a hormone to regulate carbohydrate and fat metabolism
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 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 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.
