Phenolcarboxylic acids
WebPhenols are acidic due to the dissociability of their -OH group. They are rather reactive compounds and as long as no steric inhibition due to additional side chains occurs, they form hydrogen bonds. Consequently, many flavonoids have intramolecular bonds. Another important feature is their ability to form chelate complexes with metals. WebInfobox references. L-pac produced by biotransformation of benzaldehyde.
