Water (Molecular formula: H2O) is a clear, odorless, tasteless liquid that is essential for most animal and plant life. Chemical structure model: Ball and Stick. 3D illustration.
Chemical formula of Cortisol
Folic acid, folate molecule. It is known as vitamin B9. Molecular model. 3D rendering. Illustration
A molecular model of Bisphenol A or BPA. It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses. Isolated on white.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
Dopamine ( DA) hormone molecule. Molecular model. 3D rendering. 3D illustration
A molecular model of the flavonoid Quercetin. An antioxidant and anti-inflamatory, it is used as a nutritional suplement. It is commonly found in many fruits and vegetables and is a significant chemical component of tea. Isolated on white.

Prostaglandin D2 or PGD2 is a prostaglandin that binds to the receptor PTGDR as well as CRTH2. 3d illustration
Chemical formula of Aldosterone
Mannitol is a type of sugar alcohol. It is used as a low calorie sweetener as it is poorly absorbed by the intestines. As a medication, it is used to decrease pressure in the eyes, as in glaucoma, and to lower increased intracranial pressure.
Molecular model of Adenosine triphosphate, or Adenosine-5'-triphosphate (ATP)
Bisphenol A, BPA, C15H16O2 molecule. It is precursor to polycarbonate plastics and epoxy resins. Molecular model. 3D rendering. 3D illustration
A molecular model of the plasticizer Dibutyl Phthalate or DBP. As a plasticizer it has been used in many products including adhesives, textiles, cosmetics and children's toys. There are now concerns about its health effects, particularly its effect on male health and behaviour. Isolated on white.
