In the present study, a cDNA encoding a CAD was isolated from wheat, designated as TaCAD1. A genome-wide data mining in the wheat EST database revealed another 10 CAD-like homologues, namely TaCAD2 to TaCAD11. A phylogenetic analysis showed that TaCAD1 belonged to the bona fide CAD group involved Cited for: FUNCTION, TISSUE SPECIFICITY. Ref.9.

Functional analysis of a cinnamyl alcohol dehydrogenase involved in lignin biosynthesis in wheat Qing-Hu Ma Key Laboratory of Photosynthesis and Environmental Molecular Physiology, Institute of Botany, Chinese Academy of Sciences, 20 Nanxin Cun, Xiangshan, Beijing 100093, China This MassBank Record with Accession GLS00145 contains the MS mass spectrum of 'Cinnamyl alcohol' with the InChIKey 'OOCCDEMITAIZTP-QPJJXVBHSA-N'. 2013-07-31 · Background Lignin is a significant barrier in the conversion of plant biomass to bioethanol. Cinnamyl alcohol dehydrogenase (CAD) and caffeic acid O-methyltransferase (COMT) catalyze key steps in the pathway of lignin monomer biosynthesis. Brown midrib mutants in Zea mays and Sorghum bicolor with impaired CAD or COMT activity have attracted considerable agronomic interest for their altered Involved in lignin biosynthesis. May catalyze the final step specific for the production of lignin monomers, like coniferyl alcohol, sinapyl alcohol and 4-coumaryl alcohol.1 Publication. "Brown-midrib maize (bm1) -- a mutation affecting the cinnamyl alcohol dehydrogenase gene." Cinnamyl alcohol dehydrogenase (CAD) catalyses the final step in the biosynthesis of monolignols.

Class III is conserved in land plants. The three classes differ in pat-terns of evolution and expression, implying that functional divergence has occurred among them. Our study also Cinnamyl alcohol is a naturally occurring compound that is found within cinnamon. Due to the low levels found in cinnamon, cinnamyl alcohol is usually supplied as [DB14184] within commercial products.

Thus, the functional group tolerance is sometimes low, and the poor  av N Selander · 2010 — The functional group was either transferred from the oxidizing reagent, or introduced monitored the borylation of cinnamyl alcohol (41a) and cinnamyl acetate.

Nucleophilic attack on epoxides gives a ring-opened product that possesses two functional groups located on adjacent carbon atoms. Often this ring-opening is stereo- 3.3 Effect of catalyst reduction on oxidation of cinnamyl alcohol The active phase for cinnamyl alcohol oxidation is still under debate, but the pre-reduction of Pd-based catalysts with alcohol or hydrogen before reaction has been reported to enhance the reaction rate. 17 In an attempt to address the issue of catalyst deactivation, Au–Pd/TiO 2 was first pre-reduced in situ at the reaction The end functional groups can be changed using different aromatically substituted cinnamyl alcohol derivatives. Different monomers were investigated and the presence of the functional groups was shown by NMR spectroscopy and MALDI‐ToF mass spectrometry.

Acute toxicity 168 primary oxygenated functional group is located on a ChEBI Name cinnamyl alcohol: ChEBI ID CHEBI:17177: Definition A primary alcohol comprising an allyl core with a hydroxy substituent at the 1-position and a phenyl substituent at the 3-position (geometry of the C=C bond unspecified). Sinapyl alcohol is a primary alcohol, being cinnamyl alcohol hydroxylated at C-4 and methoxylated at C-3 and -5. It has a role as a plant metabolite. It is a primary alcohol, a member of phenols and a dimethoxybenzene. It derives from a cinnamyl alcohol. Cinnamyl alcohol dehydrogenase (CAD) is a vital enzyme in the pathway of lignin biosynthesis. Cloning and marker development of the CAD gene could be helpful for lodging resistance breeding.
