Success tastes sweet for scientists

08.11.2005


A low-calorie sweetener that tastes like sugar and could help control diseases like diabetes and obesity may be closer to reality thanks to research published today.



Scientists at The University of Manchester and The University of Maryland School of Medicine in Baltimore have made a major advance in understanding what makes a substance taste sweet.

The discovery could help pave the way for the development of low-calorie sweeteners that mimic natural sugar and leave no bitter aftertaste.


“Our study has for the first time measured how sugar and some synthetic sweeteners interact with two types of taste receptors on the tongue,” said Dr Graeme Conn in Manchester’s Faculty of Life Sciences.

“Some synthetic sweeteners only interact with one receptor. We found that sugar interacts with both. Similarly, sucralose, the sweetener used in Splenda, also interacted with both receptors but with a greater intensity to sugar.

“Knowing what molecular mechanisms are at play has given us a greater understanding of what makes sugar taste sweet and will no doubt help us design better sweeteners.”

The research findings, published in the November 8 issue of the scientific journal Current Biology, have implications for diabetic patients, who need to regulate their sugar intake, as well as for tackling the growing problem of obesity.

A recent study by food firm GoLower showed that the average adult in Britain consumed 33 teaspoons of sugar a day, more than three times the recommended amount.

Much of this sugar intake was consumed through everyday food items, like baked beans, bread and cereal, as well as in tea, coffee and alcoholic drinks.

“A major goal of the food-science industry has been to create a sweetener that tastes like sugar but isn’t high in calories,” said Dr Steven Munger, of the University of Maryland School of Medicine.

“To do this, it would be invaluable to know how the natural substance interacts with taste receptors so that synthetic products can be created to mimic that interaction.

“We hope that food scientists can use our research to create sugar alternatives with the most natural taste, offering more choice to consumers who rely on low-calorie products to help control diseases like diabetes and obesity.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
