- Any of a class of aromatic yellow compounds including several that are biologically important as coenzymes or acceptors or vitamins; used in making dyes
- A quinone is a class of organic compounds that are formally "derived from aromatic compounds by conversion of an even number of u2013CH= groups into u2013C(=O)u2013 groups with any necessary rearrangement of double bonds", resulting in "a fully conjugated cyclic dione structure". The class includes some heterocyclic compounds.
- Any of a class of aromatic compounds having two carbonyl functional groups in the same six-membered ring
- (Quinones) Compounds derived from benzene and its homologues by the replacement of two atoms of hydrogen with two atoms of oxygen, and characterized by their yellow color and by being readily reduced to dihydric phenols. According to their configuration they are divided into 1.2-quinones and 1. ...
- (quinones) found in many cells, they can stabilize unpaired electrons during many energy-transfer activities. For example, the active ingredients in aloe and henna are quinones. The electron-transport process of photosynthesis uses these molecules to convert light into chemical energy. ...
- An enzymatic cofactor that plays an important role in photosynthesis and respiration. More specifically, it is part of the electron transport chain in mitochondria and chloroplast membranes.
- An aromatic carbonyl compound, which acts as an oxidizing agent.
