The “fifth district” was the “quintus” district, derived from Latin, and a prominent family from this area became known as the “quinones”, with several variations emerging. Since then the name has emigrated to Cuba, Puerto Rico, the Dominican Republic and Greater Latin America and the United States.
Quinones are ubiquitous biological pigments found in a range of living organisms (bacteria, fungi, higher plants and a few animals). They occur naturally in many forms such as benzoquinones, naphthoquinones, anthraquinones and polycyclic quinones.
In the United States, the name Chinones is the 1,211st most popular surname with an estimated 24,870 people with that name.
The Quinonez family originally lived on a piece of land shared by a group of roommates to sow, which was derived from the Spanish word quinon and finally the Latin word quinio, meaning a group of five< /b>.

Quinones are small electron transfer molecules found in virtually all cells that undergo aerobic metabolism and play an important role in oxidative stress. Quinones play a diverse role in medicine, including anti-cancer agents and anti-aging and atherosclerosis.
From a toxicological point of view, quinones have two main chemical properties that give them their reactivity in biological systems. Quinones are oxidizing agents and electrophiles, and the relative contribution of these properties to the toxicity of quinones is influenced by chemical structure, particularly by substituent effects.
The quinones are a class of organic compounds formally “derived from aromatic compounds [such as benzene or naphthalene] by conversion of an even number of -CH= groups to -C(=O)- groups each necessary rearrangement of double bonds, resulting in “a fully conjugated cyclic dione structure”.
