chalcone उदाहरण वाक्य
उदाहरण वाक्य
- It is synthesized from 4-coumaroyl-CoA and malonyl-CoA by chalcone synthase ( CHS ), a key enzyme in the phenylpropanoid pathway.
- In aurone, a chalcone-like group is closed into a 5-membered ring instead of the 6-membered ring more typical of flavonoids.
- After the generation of a thioester-linked tetraketide, a regiospecific C1, C6 Claisen condensation occurs, forming a new ring system to generate naringenin chalcone.
- Chalcone is then isomerized to naringenin by chalcone isomerase which is oxidized to eriodictyol by flavonoid 3-hydroxylase and further oxidized to taxifolin by flavanone 3-hydroxylase.
- Chalcone is then isomerized to naringenin by chalcone isomerase which is oxidized to eriodictyol by flavonoid 3-hydroxylase and further oxidized to taxifolin by flavanone 3-hydroxylase.
- Cloning of CHS from the moss " Physcomitrella patens " revealed an important transition from the chalcone synthases present in microorganisms to those present in higher plants.
- Further investigation of the phenomenon indicated that the downregulation was due to post-transcriptional inhibition of the chalcone synthase gene expression via an increased rate of messenger RNA degradation.
- Color stabilization of malvidin 3-glucoside at a higher pH can be explained by self-aggregation of the flavylium cation and copigmentation with the Z-chalcone form.
- Similarly, another intermediate naringenin chalcone is converted to the isoflavone daidzein by sequential action of three legume-specific enzymes : chalcone reductase, type II chalcone isomerase, and isoflavone synthase.
