A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
Prostaglandin D2 or PGD2 is a prostaglandin that binds to the receptor PTGDR as well as CRTH2. 3d 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
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.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.

A molecular model of Human Insulin. Isolated on black.
Sodium citrate or trisodium citrate molecule. Flavouring agent, food additive and anticoagulant. Molecular model. 3D rendering. Illustration
Rendered remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of COVID-19 (or 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 white =carbon, orange=oxygen, blue=nitrogen, white=hydrogen, red=phosphorus
Aztreonam (left, orange) inhibits the beta-lactamase from Acinetobacter species. Avibactam (red) inhibits the beta-lactamase (blue) of Clostridioides difficile.
Molecular model of lactose, a disaccharide sugar in milk.
Bovine beta-lactoglobulin protein, 3D structure. Major whey protein, present in cow milk. Important food allergen.
A molecule of sucrose, showing thermal ellipsoids.

A ball and stick + ribbons model of HIV protease - an enzyme that is the target of much AIDS and HIV research.
Maltose or maltobiose or malt sugar is a disaccharide formed from two units of glucose joined with an alpha bond. 3d illustration
3D rendering of a drug molecule
Anthrax oedema factor. Molecular model of oedema factor (EF) from the anthrax bacterium Bacillus antracis complexed with a calmodulin protein molecule. EF is one of three protein components that form the anthrax toxin. It is an enzyme that interferes with water homeostasis, leading to the accumulation of fluid in the tissues. Anthrax most commonly affects cattle, sheep and goats, but can also infect humans.
Molecular model of Adenosine triphosphate,  or Adenosine-5'-triphosphate (ATP)
One of hormone produced by the thyroid gland is thyroxine or t4 3D rendering
