CHEMICAL SYNTHESIS

METABOLISM
Aldehyde C-7 is readily oxidized in the animal body to the corresponding fatty acid, which then undergoes b-oxidation and eventually oxidized to dioxide and water.(Ref. 0021)
GENETIC INFORMATION

NOTE
Aldehyde and its simple acetals used in perfumery. Flavouring agent. Liq. with fruity odour.(Ref. 0114)
