key intermediate in shikimate and phenylpropanoid pathways.
Shikimic acid is a precursor of many alkaloids, aromatic amino
acids, and indole derivatives. Phenylpropanoid are a class of plant
metabolites based on phenylalanine. They are widely distributed in
plants fulfilling many functions including plant defense mechanism,
pigmentation and external signaling system. Phenylalanine is first
converted to cinnamates, coumarines, caffeic acids, ferulic acids,
and sinapic acids. Cinnamic acid is the precursor of these acids.
Cinnamic acid is the parent compound of its esters which are more
volatile to be transported to other parts easily. Commercial
cinnamic acid, a phenylacrylic acid structure compound, is used in
converting to its esters such as methyl, ethyl, and benzyl
cinnamate for the perfume and flavour application. Cinnamic acid
and Its derivatives including esters and carboxylic functional
derivatives are used as important components in flavours, perfumes,
synthetic indigo and pharmaceuticals. Cinnamate can act as optical
filters or deactivate substrate molecules that have been excited by
light for the protection polymers and organic substances. They,
cosmetic grades, are used as sunscreen agents to reduce skin damage
by blocking UV-A, B. Cinnamic acid is an odorless white crystalline
powder; slightly soluble in water; melting point **3 C and boiling
point **0 C.
