Catechin

Stability Light Sensitive
Applications One of the catechin isomers and a potent antioxidant that can modulate a wide range of membrane proteins. Its bilayer-modifying potency was tested using gramicidin A (gA) channels as probes. All the catechins alter gA channel function and modify bilayer properties, with a 500-fold range in potency. The gallate group causes current block, as evident by brief downward current transitions.

Procyanidin B3 is a flavonoid compound, which is a type of plant-derived polyphenol, sourced primarily from the seeds and skins of various fruits, especially grapes and apples. It functions primarily through strong antioxidant activity, neutralizing free radicals and reducing oxidative stress. This mode of action is fundamental to its potential therapeutic effects, as oxidative stress is a contributor to numerous chronic diseases.

Procyanidin B1 is a polyphenolic compound, which is a type of naturally occurring organic compound. It is primarily sourced from various plants, including grape seeds, apples, and cocoa. This compound is a proanthocyanidin, specifically a type of flavonoid, and is often found in the skins, seeds, and leaves of these plants.

(-)-Catechin is a flavonoid compound, classified as a polyphenolic antioxidant, which is predominantly derived from plant sources such as tea leaves, cocoa, and various fruits. Its molecular structure allows it to scavenge free radicals and chelate metal ions, exhibiting potent antioxidant properties. This reactive nature contributes to its ability to modulate signaling pathways and inhibit enzymatic activities related to oxidative stress and inflammation.

(-)-Gallocatechin gallate is a flavonoid compound, specifically a type of catechin, which is a phytochemical sourced primarily from tea plants, particularly green tea leaves. This compound is structurally characterized by its polyphenolic framework, which significantly contributes to its biological activity.

(+)-Gallocatechin gallate is a polyphenolic compound, which is a specific type of catechin predominantly derived from green tea leaves, Camellia sinensis. It belongs to the flavonoid class of phytochemicals, known for their diverse biological activities. The compound exhibits potent antioxidant properties by scavenging free radicals and chelating metal ions, thereby reducing oxidative stress. It also modulates various signaling pathways involved in inflammation and cell proliferation.
