2018年4月15日 · Carotenoids are a type of accessory pigment, created by plants to help them absorb light energy and convert it to chemical energy. There are two types of carotenoids, xanthophylls and carotenes, which differ only in their oxygen content.

Carotenoids serve two key roles in plants and algae: they absorb light energy for use in photosynthesis, and they provide photoprotection via non-photochemical quenching. [4]

In plants, carotenoids are essential for photosynthesis and photoprotection. They play critical roles as light harvesting pigments and structural components of photosystems. Carotenoids also provide precursors for the biosynthesis of phytohormones abscisic acid …

Carotenoids are essential pigments in photosynthetic organs along with chlorophylls. Carotenoids also act as photo-protectors, antioxidants, color attractants, and precursors of plant hormones in non-photosynthetic organs of plants.

In this review, we discuss the current research being undertaken to increase carotenoid content in plants and research the benefits to human health and the role of carotenoid derived volatiles on flavour and aroma of fruits and vegetables. Keywords: carotenoids, apocarotenoids, biofortification, flavour, nutrition, nutraceutical. 1. Introduction.

Carotenoids are lipophilic secondary metabolites derived from the isoprenoid pathway and are accumulated in most plant organs [1]. They contribute to the red, yellow and orange colors of many fruits and flowers, and are a factor in attracting pollinators to flowers.

2024年10月19日 · Carotenoids are pigments found in plants that play roles beyond their vibrant hues. These organic compounds are important for plant health, contributing to photosynthesis and protecting against environmental stressors.

Carotenoids, derived from plants (fruits and vegetables), serve as the primary source of natural carotenoids accessible to humans through their dietary intake (Gebregziabher et al., 2023).Actually, almost all plants are endowed with a powerful inherent carotenogenesis to complete light absorption, photo-protection, and energy transfer in their photosynthesis …

Carotenoids are mostly C40 terpenoids, a class of hydrocarbons that participate in various biological processes in plants, such as photosynthesis, photomorphogenesis, photoprotection, and development. Carotenoids also serve as precursors for two plant hormones and a diverse set of apocarotenoids.

Carotenoids are essential pigments found in plants that play a crucial role in photosynthesis, photoprotection, and providing color to fruits and vegetables. They are not only vital for plant ...
