Description

1 male adult wild-type rat was obtained from Inserm U1085 - Irset Research Institute (University of Rennes1, France). Animals were age 60 days and were reared under ad-lib conditions. Care and handling of all animals complied with EU directive 2010/63/EU on the protection of animals used for scientific purposes. The whole epididymis was excised from each animal immediately post-mortem, loosely wrapped rapidly in an aluminum foil and a 2.5% (w/v) carboxymethylcellulose (CMC) solution was poured to embed the epididymis to preserve their morphology. To remove air bubbles, the filled aluminum molds was gently freezed by depositing it on isopentane or dry ice, then on the nitrogen vapors and finally by progressively dipping the CMC/sample coated with aluminum foil into liquid nitrogen (or only flush with liquid nitrogen). Frozen tissues were stored at -80 °C until use to avoid degradation.

Description


Procyanidin b2 3-gallate is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3-C3, and C6-C8. Procyanidin b2 3-gallate is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Procyanidin b2 3-gallate can be synthesized from gallic acid. Procyanidin b2 3-gallate can also be synthesized into procyanidin B2. Procyanidin b2 3-gallate can be found in common grape, which makes procyanidin b2 3-gallate a potential biomarker for the consumption of this food product.
