cinnamaattiyhdisteistä

Cinnamate compounds are a group of chemical substances derived from cinnamic acid. Cinnamic acid itself is an organic compound with the formula C6H5CH=CHCOOH. It is a white crystalline solid that is sparingly soluble in water. Cinnamate compounds are found naturally in a variety of plants, particularly in cinnamon and balsam resins. They are also synthesized industrially.

The basic structure of a cinnamate compound consists of a phenyl group attached to a propenoic acid moiety. This structure can be modified through substitutions on the phenyl ring or by altering the carboxylic acid group. Many natural cinnamates are esters of cinnamic acid, where the hydroxyl group of the acid is esterified with an alcohol. For example, ethyl cinnamate and methyl cinnamate are common examples.

These compounds exhibit a range of properties and applications. Many cinnamates possess fragrant aromas and are used as flavoring agents and perfumes. Cinnamates are known for their antioxidant properties, which are attributed to the conjugated double bond system and the aromatic ring. Some cinnamate derivatives have shown potential biological activities, including antimicrobial and anti-inflammatory effects. Due to their UV-absorbing properties, certain cinnamate esters are employed in sunscreens as UV filters. Research continues to explore new applications and the biological significance of various cinnamate compounds.
