Chemical formula of Bisphenol A (BPA) with black pen. Close-up.
Chemical formula of Cortisol
Science background with molecule or atom
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.
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d 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.
Folic acid, folate molecule. It is known as vitamin B9. Molecular model. 3D rendering. Illustration

Chemical formula of Progesterone
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.
Pheochromocytoma, Site: Adrenal gland
Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases.
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.

Chemical formula of Aldosterone
Bisphenol A, BPA, C15H16O2 molecule. It is precursor to polycarbonate plastics and epoxy resins. Molecular model. 3D rendering. 3D illustration
Molecular model of lactose, a disaccharide sugar in milk.
Ferrocene is an organometallic compound. The molecule consists of two cyclopentadienyl rings bound on opposite sides of a central iron atom. 3d illustration
Scientifically correct illustration of DNA molecular structure, featuring labeled diagrams of adenine, thymine, guanine and cytosine.
Sofosbuvir is a drug approved for the treatment of hepatitis C.
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.
Bacteria culture growth on hichrome uti agar media plate in microbiology laboratory, Proteus colonies. Bacteria culture growth on a petri dish. Gram negative bacteria colonies

Molecular model of amylose, one of the two sugar components in starch.
Prostaglandin D2 or PGD2 is a prostaglandin that binds to the receptor PTGDR as well as CRTH2. 3d illustration
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
