640-03-9 Usage
Uses
Used in Agricultural and Plant Biology Research:
Antheroxanthin is used as a biomarker for assessing the efficiency of photosystem II (PSII) in plants. The higher levels of Antheroxanthin found during depressions of PSII efficiency indicate its potential role in managing light energy absorption and dissipation, which is crucial for plant health and survival.
Used in Photoprotection Studies:
Antheroxanthin serves as a key component in the study of photoprotection mechanisms in plants. Its involvement in the xanthophyll-cycle allows researchers to better understand how plants adapt to varying light conditions and protect themselves from potential damage due to excessive light exposure.
Used in Phytopigment Analysis:
Antheroxanthin is utilized as a pigment of interest in the analysis of phytopigments, which are essential for photosynthesis and other light-dependent processes in plants. The study of Antheroxanthin and its role in the xanthophyll-cycle can provide valuable insights into the overall functioning of plant pigments and their contribution to plant growth and development.
Check Digit Verification of cas no
The CAS Registry Mumber 640-03-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 640-03:
(5*6)+(4*4)+(3*0)+(2*0)+(1*3)=49
49 % 10 = 9
So 640-03-9 is a valid CAS Registry Number.

Preparation and (E/Z)-Isomerization of the Diastereoisomers of Violaxanthin
Molnar, Peter,Deli, Jozsef,Zsila, Ferenc,Steck, Andrea,Pfander, Hanspeter,Toth, Gyula
, p. 11 - 27 (2007/10/03)
Violaxanthin A (=(all-E,3S,5S,6R,3′S,5′S,6′ R)-5,6:5′,6′-diepoxy-5,6,5′,6′-tetrahydro-β, β-carotene-3,3′-diol = syn,syn-violaxanthin; 5) and violaxanthin B (=(all-E,3S,5S,6R,3′S,5′R,6′S)-5,6:5′, 6′-diepoxy-5,6,5′,6′-tetrahydro-β,β-carotene-3, 3′-diol = syn,anti-violaxanthin; 6) were prepared by epoxidation of zeaxanthin diacetate (1) with monoperphthalic acid. Violaxanthins 5 and 6 were submitted to thermal isomerization and I2-catalyzed photoisomerization. The structure of the main products, i.e., (9Z)-5, (13Z)-5, (9Z)-6, (9′Z)-6, (13Z)-6, and (13′Z)-6, was determined by their UV/VIS, CD, 1H-NMR, 13C-NMR, and mass spectra.
PREPARATION OF MONO-CIS ANTHERAXANTHINS AND DETERMINATION OF THEIR GEOMETRICAL CONFIGURATION BY (13)C-NMR SPECTRAL ANALYSIS
Molnar, P.,Radics, L.,Szabolcs, J.
, p. 477 - 486 (2007/10/02)
Using (13)C-NMR methods, the stereochemistry of eight mono-cis carotenoids obtained by stereomutation of natural (3S, 5R, 6S, 3'R)- and semisynthetic (3S, 5S, 6R, 3'R)-all-trans-antheraxanthins has been established.The carbon-13 data support our earlier p
