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

open access: yesJournal 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

open access: yesFood 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]

open access: yesFEMS 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.

Low and high responders to pharmacological doses of β-carotene: proportion in the population, mechanisms involved and consequences on β-carotene metabolism

open access: yesJournal of Lipid Research, 1998
The aim of this study was to assess the interindividual variability of chylomicron β-carotene response to a pharmacological load of β-carotene in the population, to identify the mechanisms responsible for this variability, and to evaluate its ...

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

open access: yesMarine 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.
