Catabolism and bioactive properties of chlorophylls

Abstract

Chlorophylls are fundamental molecules for life and probably the most important of all natural pigments. Although chlorophyll breakdown is inevitably associated with the loss of green color during ripening or senescence, the truth is that chlorophyll molecules continuously degrade through so-called chlorophyll turnover (lifetime of hours). In addition to their primary function, chlorophylls are in demand due to their bioactive properties. Recently, several chlorophyll derivatives have shown health promoting activities. This review also provides an updated outline of the most recent advances that have occurred in the deciphering mechanism of chlorophyll catabolism; it will also describe the novel biological properties associated with chlorophyll derivatives.

Microalgae-Derived Pigments: A 10-Year Bibliometric Review and Industry and Market Trend Analysis

“…Photosynthetic organisms predominantly present chlorophyll a and b, whereas chlorophyll c, d, and f are found exclusively in some microalgae species, algae, and photosynthetic bacteria. [ 3 , 34 ].…”

The Effect of Light on Antioxidant Properties and Metabolic Profile of Chia Microgreens

“…As reviewed in Solymosi and Mysliwa-Kurdziel [28], chlorophylls are good antioxidants because of their effective scavenging activity of reactive oxygen species (ROS) and inhibition of lipid peroxidation. Chlorophylls are most commonly used as natural food colorants, but, recently, their bioactive properties [29] have become more in focus as research has shown their emerging role as potential prebiotics in rebalancing gut microbiota in mice [30].…”

Photo-Oxidative Protection of Chlorophyll a in C-Phycocyanin Aqueous Medium

“…Reactive oxygen species (ROS) occur within cells in various forms such as superoxide (O2• ̶ ), hydroxyl (•OH), peroxyl (ROO•), alkoxyl (RO•), hydroperoxyl (HO2•), hydrogen peroxide (H2O2), and singlet oxygen ( 1 O2). Numerous studies have reported the antioxidant functions of chlorophylls [52,53]. The common experimental approach to assess ROS in different tissues of experimental animals (such as mice and rats) is to administer diets rich in copper chlorophyllins [53].…”
