SummaryThe present study focuses on the regulation of diatoxanthin (Dtx) epoxidation in the diadinoxanthin (Ddx) cycle containing algae Phaeodactylum tricornutum, Thalassiosira pseudonana, Cyclotella meneghiniana and Prymnesium parvum and its significance for the control of the photosystem II (P...detailed

Formation of neoxanthin, DIADINOXANTHIN (cas 18457-54-0) and peridinin from [14C]zeaxanthin by a cell-free system from Amphidinium carterae09/24/2019

A cell-free system prepared from an axenic culture of the alga Amphidinium carterae converted [14C]zeaxanthin into neoxanthin and then into peridinin (62%) and diadinoxanthin (38%). Peridinin, therefore, is made by the excision of three carbon atoms from a C40 carotenoid and the acetylene group ...detailed

Cadmium inhibits epoxidation of diatoxanthin to DIADINOXANTHIN (cas 18457-54-0) in the xanthophyll cycle of the marine diatom Phaeodactylum tricornutum09/10/2019

Cd has pleiotropic effects on plant physiology and in particular on photosynthesis. It has not been established yet if Cd alters the functioning of the xanthophyll cycle. To answer this question, an exponentially growing culture of the marine diatom Phaeodactylum tricornutum was incubated with C...detailed

Heteroxanthin, diatoxanthin and DIADINOXANTHIN (cas 18457-54-0) from tribonema aequale☆09/08/2019

The principal crystallizable xanthophylls of Tribonema aequale are heteroxanthin, diatoxanthin, and diadinoxanthin. The latter pigment from Tribonema is identical with the diadinoxanthin from Euglena and the diatom Nitzschia. Description and identification of the pigments have been based upon co...detailed

The lipid dependence of DIADINOXANTHIN (cas 18457-54-0) de-epoxidation presents new evidence for a macrodomain organization of the diatom thylakoid membrane09/07/2019

SummaryThe present study shows that thylakoid membranes of the diatom Cyclotella meneghiniana contain much higher amounts of negatively charged lipids than higher plant or green algal thylakoids. Based on these findings, we examined the influence of SQDG on the de-epoxidation reaction of the dia...detailed

The lifetimes of the first excited singlet states (21Ag) of diadinoxanthin and diatoxanthin, carotenoids involved in the xanthophyll cycle in some genera of algae, have been measured by femtosecond time-resolved optical spectroscopy to be 22.8 ± 0.1 ps and 13.3 ± 0.1 ps, respectively. Using th...detailed
