CAS 1401-55-4

Tannins

Description:

Tannins are a diverse group of polyphenolic compounds found in various plants, particularly in the bark, leaves, and fruits. They are known for their astringent properties, which can precipitate proteins and are responsible for the bitter taste in many plants. Tannins are classified into two main categories: hydrolyzable tannins and condensed tannins. Hydrolyzable tannins can be broken down into simpler phenolic acids upon hydrolysis, while condensed tannins are formed from the polymerization of flavonoid units and are more resistant to degradation. Tannins play significant roles in plant defense against herbivores and pathogens, and they also have various applications in food, beverages (notably in wine and tea), and traditional medicine due to their antioxidant and antimicrobial properties. The CAS number 1401-55-4 specifically refers to a type of tannin, which may have unique characteristics and applications. Overall, tannins are important compounds in both ecological and industrial contexts, contributing to flavor, color, and health benefits.
