Description

Recommended products
Pyridoxine 34-Dipalmitate 98.0%(HPLC)

Application
It has high water retention capabilities and is used in food and cosmetics. The sugar is thought to form a gel phase as cells dehydrate which prevents disruption of internal cell organelles by effectively splinting them in position. Rehydration then allows normal cellular activity to be resumed without the major lethal damage that would normally follow a dehydrationrehydration cycle. Trehalose is not an antioxidant because it is a non-reducing sugar and does not contain nucleophilic groups in its molecule. However it was reported to have antioxidant effects.

Purpose
For R&D use onlynot for drug household or other uses.

General Description
Trehalose also known as mycose or tremalose is a natural alpha-linked disaccharide formed by an -11-glucoside bond between two -glucose units. In 1832 H.A.L. Wiggers discovered trehalose in an ergot of rye and in 1859 Marcellin Berthelot isolated it from trehala manna a substance made by weevils and named it trehalose. It can be synthesised by bacteria fungi plants and invertebrate animals. It is implicated in anhydrobiosis the ability of plants and animals to withstand prolonged periods of desiccation.
