    Hydroxycinnamic Acids - an overview | ScienceDirect Topics

    Among the fruit phenolics, hydroxycinnamic acid derivatives play an important role because of both their abundance and diversity. They all derive from cinnamic acid and are essentially present as combined forms of the four basic molecules p-coumaric, caffeic, ferulic (see Figure 6), and sinapic acids.The free forms of these acids are very rare in fruits.

    an overview - ScienceDirect

    Cinnamic acids play key roles in the formation of other more complex phenolic compounds. The cinnamic acids (Figure 1) are rarely present in uncombined forms, occurring primarily as esters of quinic acid, but may also be esterified to malic or tartaric acids, or sugars.Chlorogenic acid (5-caffeoylquinicacid) (Figure 2) is perhaps the most important cinnamic acid observed in fruits .

    Bromination of trans-cinnamic acid Essay Example

    The bromination of trans-cinnamic acid was completed to determine dibromide's stereochemical structure and its mechanism.
