New complex carbohydrate discovered in barley

University of Adelaide researchers have discovered a new complex carbohydrate in barley. The first of its kind to be discovered in over 30 years, the cereal polysaccharide has potential applications in food, medicine and cosmetics.

[...] The new polysaccharide is a mix of glucose, commonly found in cellulose, and xylose, which is found in dietary fibre. Based on the relative proportions of each sugar, the hybrid polysaccharide has the potential to behave as a structural component of the wall providing strength or conversely as a viscous gel.

Further research is required to understand the new polysaccharide's potential uses. Existing polysaccharides have a wide range of uses. They improve the quality of dietary fibre in porridge and are also used extensively in biomedical and cosmetic applications.

"The properties of the new polysaccharide could be manipulated to suit the desired function, increasing the range of potential uses," says Dr Little. "The genes involved in the biosynthesis of the new polysaccharide were also discovered as part of this work. The same genes can be found in all major cereal crops – not just barley. We can now use this knowledge to find ways of increasing these polysaccharides in crops, providing the possibility of generating plant material with a range of potentially different physical properties for industrial applications."

    ...You think a throwaway joke about using BARLEY to make a wall says something of import?

    AC's are such a variable lot.
