Carotenoids are the general term for a class of important natural pigments, which are commonly found in animals, higher plants, fungi, and algae. There are many kinds of them, about 700 kinds have been discovered. It is generally composed of 8 isoprenoid units, represented by the chemical formula C40H56, and has a long central chain of 11 conjugated double bonds in the E (trans) configuration.
The leaves, flowers, fruits and roots of plants are rich in carotenoids and appear yellow, orange-red or red.
Carotenoids can not only help chlorophyll receive light energy, but also dissipate excess energy through the lutein cycle, under high temperature and strong light in the photosynthesis of chloroplasts.
Carotenoids are also the precursors of vitamin A, which have the functions of anti-oxidation, immune regulation, anti-cancer, delaying aging, and preventing night childbirth.
Molecular structure of β-carotene
The biosynthetic pathway of carotenoids is as follows:
Acetyl CoA → isomethyl pyrophosphate (C5) → geranyl pyrophosphate (C20) → colorless carotenoids [phy-toene], etc.
Applications of targeted metabolomics of carotenoids
- Study on the molecular mechanism of the color appearance of vegetables, fruits and flowers
- Study on the nutritional quality of fruits
- Research on anti-aging and antioxidant of plants, research on natural antioxidants
- Study on the regulation of carotenoid synthesis
Creative Proteomics has established a carotenoids analysis method based on the LC-MS/MS platform external standard + isotope internal standard, which can detect 10 carotenes. This method has low throughput, qualitative accuracy and can complete the absolute quantification of metabolites. Creative Proteomics can provide technical services for the entire process from sample extraction to presentation of results report.
