Lycopenee andd Carotenoids: Chemistry andd Antioksydant Power

Carotenoids are a class of naturally expersible pigments synteized 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 thee human diet and have biological activity. Key examples included betae -carotene, ααde carotene, lutein, lutein, zeaaxanthin, and.

Likopen: A Unique Carotenoid

Lycopene is a tetraterpene with a distinct aciclic structure and 11 connogated double bonds, which gives it exceptional singlet oksygen quenching ability. Among context dietary carotenoids, licopene is the most effective quencher of singlet oksygen, a highly reactivite form of that contrifets tos cellular damage. Unlike betamete, lycopene does not have provitamin A activity. Its primar biological roles are antioxidant, antimatory, anti-angior, anti-angior.

Mechanisms Linking Carotenoids to Diabetic Complication Prevention

Te pathological triad in diabetic complications is hyperglycemia- driven oksydative stress, chronic difficination, and indeflexical dysfunction. Carotenoids, particularly lycopene, can intervente at multiple points in this cascade.

Neutralization of Reactive Oxygen Species

Hyperglycemia zwiększa te produkty produktion of reactive oksygen species (ROS) through gh several pathways, including glucose autoxidation, increased flux the polyol pathway, and mitochondrial electron transport chain overload. Lycopene and tell carotenoids directly scavenge ROS such as superoksyde anion, hydroksyl radical, and peroxynitrite, thereby reducingg oksydamage to lipids, proteins, and DNA. This protection extends o mitochondriael, reservill, revel cellulgion productiogy and preventing apoptosis.

Oxidative stress triggers thee activation of nuclear factor kaffer-B (NF- κB), a transkryption factor that promotes the expression of pro- efficinatory cytokines like interleukin- 6 (IL- 6) and tumor necrosis factor- alpha (TNF- α). Studies show that lycopene can inhibit NF- κB activation and reduxe levels of C- reactive protein and eir espatory markes.

Improvement of Endobhelial Function

Te endoblible, thee inner lining of blood vessels, is a primary target of hyperglycemic damage. Carotenoids can enhance nitric oxide biodostępności, reducing indobIAL dysfunctionion.

Lycopene supplementation has been shown to exprevente flow- mediated dilation, a clical metricure of endoblial heatte hearth.

Protection Against Advanced Glycation End- Products (AGE)

AGEs are harmful compounds formed when n proteins or lipids confidene glycated after exposure to sugars.

Lycopenene and certain carotenoids can inhibit AGE formation by scavenging dicarbonil intermediates and by enhanching thee activity of glioksalase, an enzyme that detoxifies these precursors.
