Catéchine

<p>(-)-Gallocatechin is a type of flavan-3-ol, specifically a catechin, which is a subtype of polyphenol. This compound is naturally sourced from various plants, particularly abundant in green tea leaves. It is part of the broader catechin family, known for possessing potent antioxidant potential.</p>

<p>Catechin 7,4'-di-O-gallate is a naturally occurring flavonoid compound, which is derived from various plants, particularly those rich in catechins, such as tea leaves and certain fruits. As a member of the polyphenol class, it is known for its powerful antioxidant properties, which enable it to neutralize free radicals and mitigate oxidative stress. Additionally, its structure allows for strong anti-inflammatory effects by modulating signaling pathways and inhibiting the production of inflammatory mediators.</p>

<p>Epigallocatechin gallate, also known as EGCG, is a flavonoid that provides antioxidant properties to plants. It also inhibits telomerase, and enzyme that elongates chromosomes, and DNA methyltransferase, that transfers a methyl group to cytosine in the DNA chain.</p>

<p>(±)-Catechin is a type of flavonoid, a class of compounds known for their diverse range of biological activities. It is primarily sourced from a variety of plants, including tea leaves, cocoa, and certain fruits, where it exists as a natural antioxidant. The mode of action of (±)-catechin involves scavenging free radicals, thereby protecting cells from oxidative stress and potential damage. This protective mechanism is largely attributed to its polyphenolic structure, allowing it to neutralize reactive oxygen species (ROS).</p>

<p>3'-O-Methylcatechin is a naturally occurring flavonoid, which is derived from various plant sources, such as tea and certain fruits. It belongs to the class of compounds known as catechins, which are polyphenolic compounds widely recognized for their beneficial health effects. The methylation at the 3' position distinguishes it from other catechins, potentially influencing its bioavailability and biochemical activity.</p>

<p>Epigallocatechin gallate, also known as EGCG, is a flavonoid that provides antioxidant properties to plants. It also inhibits telomerase, and enzyme that elongates chromosomes, and DNA methyltransferase, that transfers a methyl group to cytosine in the DNA chain.</p>

<p>(-)-Gallocatechin 3-(4''-O-methyl)gallate is a naturally occurring flavonoid, which is a type of polyphenolic compound. It is derived from plant sources, specifically found in certain teas and other botanical products. This compound exhibits its mode of action primarily through its antioxidant properties, where it scavenges free radicals and inhibits oxidative stress, thereby protecting cellular systems from damage.</p>

<p>(+)-Gallocatechin is a flavonoid, which is a type of polyphenol compound, naturally found in a variety of plant sources such as tea leaves, cocoa, and certain fruits. It is structurally related to other catechins, sharing similar properties and biological activities. As an antioxidant, (+)-Gallocatechin acts by scavenging free radicals, thereby inhibiting oxidative stress—a process linked to various chronic diseases and aging.</p>
