Purification of Zein and Xanthophylls From Corn by Process Chromatography
"A preliminary process design and economic analysis of the process suggested good economic returns by combining SEC and AC. About 80% of the capital cost and 85% of the operating cost of the process, as it stands now, is due only to the stationary phase. Our studies on the characteristics of the …

INTERRELATIONSHIPS BETWEEN MACULAR CAROTENOIDS, RETINAL MORPHOMETRY, AND COGNITIVE FUNCTION IN PERSONS WITH MULTIPLE SCLEROSIS
… Recently, lutein and zeaxanthin, dietary xanthophylls, have been shown to be associated with cognitive health. Although xanthophylls are not recognized to be essential, their lack of endogenous de novo synthesis necessitates regular dietary consumption to derive benefits. Macular …

Η ΦΩΤΟΣΥΝΘΕΣΗ ΤΟΥ ΦΥΤΟΥ ΤΗΣ ΠΙΚΡΟΔΑΦΝΗΣ (NERIUM OLEANDER) ΚΑΙ Ο ΦΩΤΟΣΥΝΘΕΤΙΚΟΣ ΜΗΧΑΝΙΣΜΟΣ ΑΥΤΟΥ
… HAND, THE PATTERN OF THE SEASONAL CHANGES OF XANTHOPHYLLS CLEARLY CONTRASTS THAT OF THE LHCP(9/B)-II' THESE DATA ARE IN ACCORDANCEWITH OUR OBSERVATIONS ON THE ULTRASTRUCTURE OF CHLOROPLAST THYLAKOIDS IN NERIUM OLEANDER, WHICH REVEAL AN INCREASE A GRANA STACKING IN THE SUMMER AND A SUBSEQUENT …

Response of selected warm-season turfgrasses and ornamental monocots to short-term, high concentration, ozone fumigation
… more â-carotene and a quicker engagement of the xanthophylls cycle than the other species in this study was tolerant to increased ozone. This suggests that closing the stomata to exclude ozone is important but does not repair or detoxify the ozone and/or reactive oxygen species that have already …

Role of xanthophyll and water-water cycles in the protection of photosynthetic apparatus in Arbutus unedo and Arabidopsis thaliana
… gene expression is higher during the night when xanthophylls are mostly epoxidated and VDE activity is supposed to be very low than during the day. The importance of the water-water cycle in protecting the chloroplasts from light stress has been examined through Arabidopsis plant with a …

Understanding The Carotenoid Biosynthesis Pathway in Orange Actinidia Species
… yellow fruits, whereas green fruit accumulated xanthophylls (primarily lutein). Transcriptomic analysis between OF and GF revealed upregulation of carotenoid pathway genes (DXS, PSY2, GGPPS, PDS, Z-ISO, and ZDS) in OF fruit during ripening (a contrast from GF). Increased expression of …

Stress responses of the marine diatom <i>Skeletonema</i> spp. to polyunsaturated aldehydes (PUAS)
… diatom. In addition, an enhanced synthesis of xanthophylls in OCT A-exposed <i>S. marinoi</i> cells was observed, likely to act as antioxidants against ROS production thereby assuring the maintenance of the photosynthetic performance at intermediate concentrations of PUAs. …

Functional analysis of plastid-encoded genes
… PSII subunits, (ii) the rate of deepoxydation of xanthophylls, and (iii) the kinetics and amplitude of non-photochemical quenching. The proposed position of PsbZ in close proximity to CP43 enables the protein to interact with PSII cores to elicit an adaptation process in response to excess light …
