Diethylaminohydroxybenzoyl hexyl benzoate
other name: UV-A-PLUS
Appearance: Light yellow Powder
CAS No:Â *********5
Uvinul A plus Assay ≥ *8%
The marine chlorophycean Dunaliella tertiolecta Butcher grown under
controlled laboratory conditions was exposed to UV-A (*0.2 W
m*2), UV-B (1.6 W
m*2) or UV-A plus UV-B (*0 W
m*2/1.5 W m*2) in connection with white light (**0
W m*2) radiation for up to 5
h at *0 oC. Uptake of
*5N-ammonium (5 or **0 M)
was more affected by UV-B and UV-A plus UV-B radiation than by
UV-A. Pattern of pigments varied in dependence on the exposure time
(2 or 5 h) and the waveband of the applied UV as well as of the
used ammonium concentration. The xanthophyll cycle was more
affected by UV-A plus UV-B radiation than by UV-B or UV-A. UV-A and
UV-B irradiance resulted in an increase of main amino acid
biosynthesis and an enhancement of the main free amino acid pools.
Changes in the pattern of the free amino acid pools were found in
dependence on the applied ammonium concentration (5 or **0 M).
Contents of AMP, ADP and ATP were also differently affected by UV
radiation in dependence on the ammonium concentration. Results are
discussed in relation to the UV effects on photosynthetic pigments,
energy supply and the key enzymes of the carbon and nitrogen
metabolism.
