1. Molecular Weight Definition

1. Molecular Weight Definition

Molecular weight, often denoted by the symbol "M", is a fundamental physical property of a molecule. It refers to the mass of one mole of a substance, which is the amount of substance that contains as many elementary entities (such as atoms, molecules, ions, or electrons) as there are atoms in 12 grams of carbon-12. This unit is expressed in atomic mass units (amu) or Daltons (Da), where one amu is approximately equal to the mass of one nucleon (proton or neutron).

In the context of Grape Seed Extract, molecular weight is particularly important because it can influence the bioavailability, solubility, and the overall effectiveness of the compounds found within the extract. The molecular weight of a compound in Grape Seed Extract, such as proanthocyanidins or other polyphenols, can determine how well it can be absorbed by the body and how it interacts with biological systems. Understanding the molecular weight of these compounds is crucial for their use in various applications, including pharmaceuticals, cosmetics, and dietary supplements.
