Myricetin: a Multifunctional Flavonol in Biomedicine [PDF]

open access: yesCurrent Pharmacology Reports, 2022
The root cause of many diseases like CVD, cancer, and aging is free radicals which exert their effect by interfering with different metabolic pathways. The sources of free radicals can be exogenous, like UV rays from sunlight, and endogenous due to different metabolic by-products.In our body, there are defense mechanisms present, such as antioxidant ...
