The invention provides a [beta]-carotenoid ketolase mutant, which is obtained through a directed evolution means, nucleotide sequences for encoding the mutant, a recombinant expression vector containing a mutant gene, expression in saccharomyces cerevisiae and application of a genetic engineering ...
aBeta-carotene is a member of the carotenoid family, a group of powerful antioxidants that also includes alpha-carotene, lycopene, zeaxanthin, and lutein. However, of all the carotenoids, only alpha-carotene and beta-carotene are converted to significant amounts of vitamin A in the body, and ...
well-nourished women during the first month of lactation.This study investigated milk carotenoid concentrations during days 4-32 postpartum and assessed the effects of maternal beta-carotene supplementation.Subjects (n = 21; aged 19-39 y) were randomly assigned to receive beta-carotene (30 mg/d)...
> Carotenoid Complex Reviews Beta Carotene is the best known of the entire carotenoid family, however, there are hundreds of other carotenoids. Today, science is exploring the benefits of the lesser-known carotenoid. The most revolutionary new knowledge in nutritional science comes from the discovery...
