Bioactive Lipophilic Antioxidants (Carotenoids, Tocols, Retinol, and Coenzyme Q10) in Human and Animal Tissues: Development and Validation of a Rapid Extraction and Chromatographic Method for Nutrition and Health Studies [PDF]

open access: yesAntioxidants
A rapid and robust analytical method was validated for the simultaneous extraction and quantification of carotenoids and other lipophilic antioxidants (tocopherols, tocotrienols, retinol and coenzyme Q10) in human and animal tissues using a tandem RRLC ...

Preliminary Data on the Safety of Phytoene- and Phytofluene-Rich Products for Human Use including Topical Application [PDF]

open access: yesJournal of Toxicology, 2018
The colorless carotenoids phytoene and phytofluene are comparatively understudied compounds found in common foods (e.g., tomatoes) and in human plasma, internal tissues, and skin. Being naturally present in common foods, their intake at dietary levels is

Isolation of Carrot Chromoplasts and Assessment of Their Carotenoid Content and Bioaccessibility [PDF]

open access: yesMolecules
The bioaccessibility (fraction of compounds released from the food matrix and available for absorption) and carotenoid content of carrot chromoplasts obtained through high-speed centrifugation using sucrose gradients were assessed.

Dietary carotenoids and breast cancer risk: evidence from a large population-based incident case-control study [PDF]

open access: yesNutrition & Metabolism
Background Although mechanistic studies suggest protective roles for carotenoids against breast cancer (BC), human studies yield inconsistent findings. Few have comprehensively evaluated dietary intake of individual and grouped carotenoids in relation to

Metabolically engineered plant cell cultures as biofactories for the production of high-value carotenoids astaxanthin and canthaxanthin [PDF]

open access: yesScientific Reports
Astaxanthin and canthaxanthin are high-value carotenoids with growing demand due to their antioxidant properties and applications in food, cosmetic, and pharmaceutical sectors. However, natural sources are limited and current production methods are often

Hot Spots of Phytoene Desaturase from Rhodobacter sphaeroides Influencing the Desaturation of Phytoene [PDF]

open access: yesCatalysts, 2021
Phytoene desaturase (CrtI, E.C. 1.3.99.31) shows variable desaturation activity, thereby introducing different numbers of conjugated double bonds (CDB) into the substrate phytoene. In particular, Rhodobacter sphaeroides CrtI is known to introduce additional 6 CDBs into the phytoene with 3 CDBs, generating neurosporene with 9 CDBs.

Evaluation of Cellular Uptake and Removal of Chlorpropham in the Treatment of Dunaliella salina for Phytoene Production

open access: yesMarine Drugs, 2022
Chlorpropham is a carbamate herbicide that inhibits cell division and has been widely used as a potato sprout suppressant. Recently we showed that the microalga Dunaliella salina treated with chlorpropham massively accumulated the colourless carotenoids ...

Stereoisomers of Colourless Carotenoids from the Marine Microalga Dunaliella salina

open access: yesMolecules, 2020
Carotenoids comprise a diverse range of naturally occurring stereoisomers, which differ in their physico-chemical properties. Their biosynthesis begins with phytoene, which is a rarity among carotenoids because it is colourless.
