One such nutrient is the important brain chemical GABA (PR is thus often referred to as "GABA rice"), and animal studies have shown that a PR-rich diet can improve cognitive function. Other studies have found that PR can also act as an anti-diabetic.<br /><br />The chemicals behind this effect were unknown, but now Robert Yu and colleagues used mass spectrometry and nuclear magnetic resonance approaches and identified the bioactive compounds as ASGs, a diverse family of molecules that consists of a glucose derivative, fatty acids, and sterols. The ASGs were concentrated in the rice bran (outer layer) and not the seed, so they would not be found in white rice.<br /><br />The researchers then demonstrated that the ASGs had the ability to activate enzymes related to diabetes, and this activation required the acyl chemical group; regular steryl glucosides (SGs) had no effect. And, although ASGs are found in many plants, soybean derived ASGs had no effect on the diabetic enzymes, indicating the ASG complement specific to rice may be unique in its diabetic benefits.<br /><br /><br />© 1995-2008 ScienceDaily LLC Captcha: Please Enter Code : * Time Zone: * Select the time zone Vocabularies Newsletter: Domain: Show summary in full view Input format Filtered HTML Web page addresses and e-mail addresses turn into links automatically.
