The enzyme, acyl CoA: monoacylglycerol acyltransferase 2 or Mgat2 is found in the intestines and plays an important part in the uptake of dietary fat by catalyzing a critical step in making triglyceride, a kind of fat. Triglyceride accounts for nearly one-third of the fat eaten by people in developed countries. http://www.physorg.com/news156419535.html Medicine & Health Mon, 16 Mar 2009 10:53:09 EST news156419535 People who sleep less than six hours a night appear to have a higher risk of developing impaired fasting glucose - a condition that can precede type 2 diabetes, researchers reported at the American Heart Association's 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. http://www.physorg.com/news156011381.html Medicine & Health Wed, 11 Mar 2009 17:30:23 EST news156011381 We know that lifespan can be extended in animals by restricting calories such as sugar intake. Now, according to a study published in the journal PLoS Genetics, Université de Montréal scientists have discovered that it's not sugar itself that is important in this process but the ability of cells to sense its presence. http://www.physorg.com/news155550999.html Chemistry Fri, 06 Mar 2009 08:36:51 EST news155550999 As researchers continue to examine the role of sweeteners in the diet, it's important that people understand the differences among various ingredients used in scientific studies, according to the Corn Refiners Association (CRA). Interchanging two distinctly different ingredients, such as pure fructose and high fructose corn syrup, creates factually incorrect conclusions and misleads consumers. http://www.physorg.com/news155397066.html Medicine & Health Wed, 04 Mar 2009 13:52:05 EST news155397066 The study, published in the Journal of Clinical Endocrinology & Metabolism, was led by Jill P.
