Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A

open access: yesJournal of the American Oil Chemists' Society, Volume 103, Issue 9, Page 1079-1097, September 2026.
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Table_2_Assessing the Role of Carotenoid Cleavage Dioxygenase 4 Homoeologs in Carotenoid Accumulation and Plant Growth in Tetraploid Wheat.DOCX

open access: yes, 2021
The dietary needs of humans for provitamin A carotenoids arise from their inability to synthesize vitamin A de novo. To improve the status of this essential micronutrient, special attention has been given to biofortification of staple foods, such as ...

Directed evolution of Arabidopsis thaliana carotenoid cleavage dioxygenase 1 [PDF]

open access: yes, 2011
Arabidopsis thaliana Carotenoid Cleavage Dioxygenase 1 (AtCCD1) is the role model for CCDs, a class of enzymes that cleave highly specific C=C double bonds in carotenoids and apo-carotenoids.

Enhanced Production of Apocarotenoids by Salicylic Acid Elicitation in Cell Suspension Cultures of Saffron (Crocus sativus L.)

open access: yesHorticulturae, 2022
A cell suspension culture of saffron (Crocus sativus L.) was previously established from style-derived calli to obtain an in vitro system for crocin, an uncommon and valuable water-soluble apocarotenoid, and carotenoid production suitable for future ...

Reactive Oxygen Species in Breast Cancer: From Redox Dysregulation to ROS‐Responsive Therapeutics

open access: yesCell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT Breast cancer is the most frequently diagnosed malignancy among women worldwide, with 2.3 million new cases and approximately 670,000 deaths reported in 2022 alone. Despite advances in therapy, metastasis and acquired drug resistance remain major clinical challenges.

Carotenoid cleavage in chromoplasts of white and yellow-fleshed peach varieties

open access: yes, 2018
Background: In peach fruit, carotenoid accumulation in the mesocarp causes the difference between yellow and white genotypes. The latter are generally characterized by a peculiar and more intense aroma, because of higher release of volatiles deriving ...

Genomewide Analysis of Carotenoid Cleavage Dioxygenases in Unicellular and Filamentous Cyanobacteria [PDF]

open access: yes, 2012
Carotenoid cleavage dioxygenases (CCDs) are a group of enzymes that catalyze the oxidative cleavage steps from carotenoids to various carotenoid cleavage products. Some ccd genes have been identified and encoded enzymes functionally characterized in many

The potato carotenoid cleavage dioxygenase 4 catalyzes a single cleavage of β-ionone ring-containing carotenes and non-epoxidated xanthophylls

open access: yes, 2015
Down-regulation of the potato carotenoid cleavage dioxygenase 4 (StCCD4) transcript level led to tubers with altered morphology and sprouting activity, which also accumulated higher levels of violaxanthin and lutein leading to elevated carotenoid amounts.
