3deoxyanthocyanidin

3deoxyanthocyanidins are a class of plant pigments belonging to the broader flavonoid group. Unlike common anthocyanidins, which possess a hydroxyl group at the 3-position of the C-ring, 3deoxyanthocyanidins lack this specific functional group. This structural difference influences their chemical properties, including their color and stability. These compounds are found in various plant species, contributing to coloration in flowers, fruits, and leaves, although their presence is less widespread than their 3-hydroxy counterparts. The specific colors exhibited by 3deoxyanthocyanidins can range from yellow to orange and red, depending on their substitution patterns and the pH of their environment. Research into 3deoxyanthocyanidins has explored their potential biological activities, including antioxidant and antimicrobial properties, although further investigation is ongoing. Their biosynthesis pathway shares similarities with other flavonoids but diverges at a key enzymatic step related to the 3-position of the C-ring. Examples of 3deoxyanthocyanidins include apigeninidin and luteolinidin.
