The difference between trans-resveratrol and resveratrol

The difference between trans-resveratrol and resveratrol

The difference between trans-resveratrol and resveratrol generally refers to the difference between trans-resveratrol and cis-resveratrol, and the difference between the two is not big. Although the molecular formula of the two is the same, the difference in the shape of folding and bending in space may lead to differences in physicochemical properties or efficacy. Therefore, the difference is mainly in the stability and physiological activity. Compared with the cis-structured resveratrol, the resveratrol of the trans structure shows stronger stability and physiological activity.

Resveratrol is a natural polyphenolic plant antibiotic that is produced when plants are attacked by pathogens. Trans-resveratrol is the natural form of resveratrol, while cis-resveratrol is the isomerized form produced by plants under the influence of ultraviolet light, but the cis-isomer is more photosensitivity. , It is easy to decompose, so it is difficult to extract and purify. Resveratrol in nature exists in the form of trans form, with very few cis forms.

But both are usually synthesized in grape leaves and grape skins, and are bioactive components in wine and grape juice. It is easy to absorb such substances orally and has certain antioxidant, anti-inflammatory and cardiovascular protection effects, but it is difficult to achieve the above effects in terms of daily intake.
