•  Steroid

  A steroid is a terpenoid lipid characterized by its sterane core and additional functional groups. The core is a carbon structure of four fused rings: three cyclohexane rings and one cyclopentane ring. The steroids vary by the functional groups attached to these rings and the oxidation state of the rings. Hundreds of distinct steroids are found in plants, animals, and fungi. All steroids are made in cells either from the sterols lanosterol (animals and fungi) or cycloartenol (plants).

•  Runic alphabet

  The runic alphabets are a set of related alphabets using letters known as runes to write various Germanic languages prior to the adoption of the Latin alphabet and for specialized purposes thereafter. The Scandinavian variants are also known as futhark; the Anglo-Saxon variant is futhorc (due to sound changes undergone in Old English by the same six letters). Runology is the study of the runic alphabets, runic inscriptions, runestones, and their history.
