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

Halofantrine is a drug used to treat malaria. Halofantrine's structure contains a substituted phenanthrene, and is related to the antimalarial drugs quinine and lumefantrine. 3d illustration
Pheochromocytoma, Site: Adrenal gland
Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases.
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.
Acetyl-CoA, acetyl coenzyme A molecule. Key coenzyme in fatty acid biosynthesis, Krebs cycle, citric acid cycle. Molecular model. 3D rendering. Illustration
Chemical formula of melatonin
Organic Carnauba Wax in Chemical Watch Glass with molecular structure place next to beaker and \nPlatycerium stemaria fern. Chemical ingredient used in cosmetic industry.
Molecular model of lactose, a disaccharide sugar in milk.
Tryptophan or Trp is an alpha-amino acid that is used in the biosynthesis of proteins, 3d illustration
A ball and stick model of N,N-Diethyl-meta-toluamide, commonly known as DEET. The most common active ingredient in insect repellents. Isolated on white.
serotonin molecule chemical structure, one of brain happiness chemicals - rough sketch on art paper, health, chemistry and physiology concept
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.
Bisphenol A, BPA, C15H16O2 molecule. It is precursor to polycarbonate plastics and epoxy resins. Molecular model. 3D rendering. 3D illustration

Xaliproden (codenamed SR57746) is a drug which acts as a 5HT1A agonist and has been proposed for use in the treatment of several neurodegenerative conditions including amyotrophic lateral sclerosis (ALS) and Alzheimer's disease.
Molecular Model of Vitamin D.
Prostaglandin D2 or PGD2 is a prostaglandin that binds to the receptor PTGDR as well as CRTH2. 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.
