See all on Wikipediahttps://en.wikipedia.org/wiki/TanninTannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term tannin (from Anglo-Norman tanner, from Medieval Latin tannāre, from tannum, oak bark) refers to the use

Tannin är polyfenoler från växter som länkar samman proteiner så att de antingen fälls ut eller krymper. I växten förvaras tanninet i vakuoler som går sönder om någon äter av den. Detta är ett skydd för att göra växten svårsmält och illasmakande, främst för insekter. Garvsyra är en tanninblandning som traditionellt används för garvning av läder.

From Simple English Wikipedia, the free encyclopedia. Tannins are bitter-tasting chemical compounds that bind proteins. Tannins are present in the following: Wine. Tea. Cannabis. Tannins are also used in the treatment of leather, to make it more durable. Natural tannins for this purpose come from oak trees, but synthetic tannins are more used.

- Condensed tannins are polymers formed by the condensation of flavans. They do not contain sugar residues. They are called proanthocyanidins as they yield anthocyanidins when depolymerized under oxidative conditions. Different types of condensed tannins exist, such as the procyanidins, propelargonidins, prodelphinidins, profisetinidins, proteracacin...

Tannic acid is a specific form of tannin, a type of polyphenol. Its weak acidity ( pK a around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C 76 H 52 O 46, which …

Stannin. Stannins are small proteins that consist of a single transmembrane helix, an unstructured linker domain, and a cytoplasmic domain. The transmembrane region contains a conserved cysteine residue (Cys32) that, together with Cys34 found in the stannin unstructured linker domain, constitutes the putative trimethyltin -binding site, close ...
