Erythropoietin is a glycoprotein cytokine secreted by the kidney in response to cellular hypoxia; it stimulates red blood cell production in the bone marrow. Erythropoietin is also produced in perisinusoidal cells in the liver. Liver production predominates in the fetal and perinatal period; renal production predominates in adulthood.

Singlet oxygen glows red as it decays from the singlet excited state to the triplet ground state : Singlet oxygen is utilised in organic syntheses, eg. Diels-Alder reaction. Ozone has a bluish colour.

The dihydrogen monoxide parody involves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO), or "hydroxylic acid" in some cases, and listing some of water's well-known effects in a particularly alarming manner, such as accelerating corrosion and causing suffocation. The parody often calls for dihydrogen monoxide to be banned, regulated, or labeled as dangerous. It illustrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears.

The green tint found in most tempered glass is a result of iron used in the production of glass sheets, where it is added as an ingredient to act as a lubricant. In fact, except in manufacturing processes designed to minimize iron use to avoid the green tint, you’ll find that green cast in all sheets of glass–not just tempered glass

In the hypothalamus, oxytocin is made in magnocellular neurosecretory cells of the supraoptic and paraventricular nuclei, and is stored in Herring bodies at the axon terminals in the posterior pituitary. It is then released into the blood from the posterior lobe (neurohypophysis) of the pituitary gland.

Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a pale blue, clear liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent and antiseptic.

The Class D fire use combustible metal as its fuel source. Examples of such combustible metals include titanium, magnesium, aluminum, and potassium. To extinguish a Class D fire, use a dry powder agent. This absorbs the heat that fire requires to burn and smothers it as well.
