Daidzein Analysis Service

Online Inquiry

Daidzein (7-hydroxy-3-(4-hydroxyphenyl)-4H-chromen-4-one) is a naturally existing compound found exclusively in soybeans and other legumes and structurally belongs to a class of compounds called isoflavones. The biosynthesis of daidzein starts with L-phenylalanine and undergoes a general phenylpropanoid pathway where the shikimate derived aromatic ring is shifted to the adjacent carbon of the heterocycle. The process begins with phenylalanine ligase cleaving the amino group from L-Phenylalanine forming the unsaturated carboxylic acid and cinnamic acid. Cinnamic acid is then hydroxylated by membrane protein cinnamate-4-hydroxylase to form p-coumaric acid, which then acts as the starter unit which gets loaded with coenzyme A by 4-coumaroyl: CoA-ligase. The starter unit (A) then undergoes three iterations of malonyl-CoA resulting in (B), which enzymes chalcone synthase (CHS) and chalcone reductase (CHR) modify to obtain trihydroxychalcone. CHR is NADPH dependent. Chalcone isomerase (CHI) then isomerizes trihydroxychalcone to liquiritigenin, the precursor to daidzein. Daidzein are used as signal carriers and defence responses to pathogenic attacks in vivo. In humans, recent research has shown the viability of using daidzein in medicine for menopausal relief, osteoporosis, blood cholesterol, and lowering the risk of some hormone-related cancers, and heart disease. Scientists at Creative Proteomics take advantage of highly quantitative methods with high-performance liquid chromatography (HPLC) for the determination of daidzein related metabolites levels in various samples.
