Effects of prepartum supplementation of β-carotene on colostrum and calves

Journal of Dairy Science, 2022
: Little is known about transfer of dietary β-carotene into colostrum, its absorption by the calf, and its effects on retinol and α-tocopherol in the calf when the dam's dietary vitamin A is adequate.

Study on the interaction between β-carotene and gut microflora using an in vitro fermentation model

Food Science and Human Wellness, 2023
β-Carotene, a typical non-oxygenated carotenoid, is the most efficient source of retinol (VA). The low bio-availability of β-carotene lead to large accumulation in colon; however, the relationship between β-carotene and gut microflora remains unclear ...

Isolation of a carotenoid biosynthesis gene coding for ζ-carotene desaturase fromAnabaenaPCC 7120 by heterologous complementation [PDF]

FEMS Microbiology Letters, 1993
A screening procedure for carotenoid genes involving heterologous complementation with two different plasmid constructs was developed. The plasmids contained the crtE and crtB genes from Erwinia unredovora together with the phytoene desaturase gene from either Rhodobacter capsulatus or Synechococcus PCC 7942. Transformation in E.

Effects of β-carotene on glucose metabolism dysfunction in humans and type 2 diabetic rats

Acta Materia Medica, 2022
Background Type 2 diabetes mellitus (T2DM) is a common chronic disease that is strongly associated with cardiovascular risk. Long-term high blood glucose levels may induce cardiomyocyte apoptosis, cardiac dysfunction and suppress fetal cardiomyocyte ...

Cloning and Functional Characterization of a Lycopene β-Cyclase from Macrophytic Red Alga Bangia fuscopurpurea

Marine Drugs, 2017
Lycopene cyclases cyclize the open ends of acyclic lycopene (ψ,ψ-carotene) into β- or ε-ionone rings in the crucial bifurcation step of carotenoid biosynthesis.

ROS Induce β-Carotene Biosynthesis Caused by Changes of Photosynthesis Efficiency and Energy Metabolism in Dunaliella salina Under Stress Conditions

Frontiers in Bioengineering and Biotechnology, 2021
The unicellular alga Dunaliella salina is regarded as a promising cell factory for the commercial production of β-carotene due to its high yield of carotenoids. However, the underlying mechanism of β-carotene accumulation is still unclear. In this study,

Selection of Indonesia Cassava (Manihot esculenta Crantz) Genotype as Source of β-Carotene

Biodiversitas Journal of Biological Diversity, 2008
Fourteen genotypes of Indonesia cassava (Manihot esculenta Crantz) of two generations were evaluated for β-carotene content. The β-carotene content of tubers and leaves were determined by spectrophotometry method. Other parameterssuch as water and ash contents were also evaluated. Results showed that β-carotene content of tubers of fourth generation(

Functional analysis of γ-carotene ketolase involved in the carotenoid biosynthesis ofDeinococcus radiodurans [PDF]

FEMS Microbiology Letters, 2009
Deinococcus radiodurans strain R1 synthesizes a unique ketocarotenoid product named deinoxanthin. The detailed steps involved in the biosynthesis of deinoxanthin remain unresolved. A carotene ketolase homologue encoded by dr0093 was inactivated by gene mutation to verify its function in the native host D. radiodurans. Analysis of the carotenoids in the
