Description

General description

Epicatechin is a flavanol, that belongs to the class of secondary, polyphenolic plant metabolites.

Application

(-)-Epicatechin has been used:
• to examine its biological effects in cell lines from human gender-specific cancers
•  to study its antiviral activity
•  to test its ability to regenerate this enzymatic activity both in vitro at the isolated MPO−H2O2−Cl- system and ex vivo in human polymorphonuclear leukocytes (PMNs)

Packaging

1, 5 mg in glass bottle

Biochem/physiol Actions

This antioxidant is found in chocolate. (-)-Epicatechin is linked with cardiovascular effects. It is considered as a dependable standard due to its availability in cacao seeds and cocoa products. The halogenating activity of myeloperoxidase can be restored by (-)-epicatechin.
