General description

Carotenoids are natural products used in the food, animal feed, nutraceutical, and pharmaceutical industries. α-Carotene, a carotenoid with one β-ring and one ε-ring, is commonly present in the food. Orange carrots show a high concentration of α-carotene.

Application

α-Carotene may be used as a standard in high-performance liquid chromatography (HPLC) for carotenoid quantification in Corynebacterium glutamicum.

Biochem/physiol Actions

α-Carotene exhibits provitamin A activity. It can act as an efficient inhibitor than β-carotene on certain growth factors, like N-myc activity. α-Carotene serves as a good biomarker for fruit and vegetable consumption. High serum concentrations of α-carotene are associated with lower cardiovascular disease (CVD) mortality.

Aim of study was to find the most suitable LC column for generic carotenoid screening. To represent the diversity of carotenoids in nature and to optimize chromatographic separation, a set of carotenoid standards was carefully chosen to account for the

The carotenoid, α-carotene, is very beneficial for human health and wellness, but microbial production of this compound is notoriously difficult, due to the asymmetric rings on either end of its terpenoid backbone. Here, we report for the first time the

Carotene hydroxylases catalyze the hydroxylation of α- and β-carotene hydrocarbons into xanthophylls. In red algae, β-carotene is a ubiquitously distributed carotenoid, and hydroxylated carotenoids such as zeaxanthin and lutein are also found. However, no enzyme with carotene hydroxylase activity had
