They exist in nature in many forms such as benzoquinones, naphthoquinones, anthraquinones, and polycyclic quinones. For example, the K vitamins (phylloquinone) are naphthoquinones. WebThere are three basic classes of pigments. Chlorophylls are greenish pigments which contain a porphyrin ring.This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. cinema shopping botafogo praia shopping
