Lycopenee andd Carotenoids: Chemistry andd Antioksydant Power

Carotenoids are a class of naturally expersident pigments syntetyzed by plants, algae, and some bacteria. They ary responsible for the red, orange, and yellow hues in fruts and vegetables. More than 600 carotenoids exist in nature, but only about 30 to 50 are common found in the human diet and have biological activity. Key examples includide beta- carotene, -carotene, -carotene, lutein, zeaeganthin, and.

Likopen: A Unique Carotenoid

Lycopene is a tetraterpene with a distinct aciclic structure and 11 convergated double bonds, which gives it exceptional singlet oksygen quenching ability. Among contrin dietary carotenoids, licopene is the mott effective quencher of singlet oksygen, a highly reactivite form of oksygen that contributes o cellular damage. Unlike betae -carotene, lycopene does not have provitamin A activity. Its primary biological roles are antioksydant, antivitacory, anti-anti-anti-angic.

Mechanisms Linking Carotenoids to Diabetic Complication Prevention
