Areas of Fat ending near to cells

Researchers have found one the basic components of fat metabolism, which is important news, as diseases related to obesity are on rise.

Lipid Droplets

Lipid Droplets

Up till now, it was a mystery how the metabolism of fat takes place from increased level of the hormones like adrenaline as a result of fight or flight response and/or physical activity.

Fats are present in the particular compartments within the fat cell. These compartments are referred to as “Lipid Droplets” (LD). It was an idea that the proteins involved in the metabolism of fats must present in close proximity on the surface of the lipid droplets and have to act together. This bunching of proteins takes place with the help of, what is called as, anchoring proteins.

Researchers from Taskén group have demonstrated the important role of the anchoring protein OPA1 in lipid metabolism. This research published in the EMBO journal. Continue reading

Why I am fat? What to do?

Obesity is a chronic disorder that has multiple causes. Obesity in childhood is a growing problem in developed countries.

About 25% of children in US are over weight and 11% are obese (unhealthily overweight). Childhood obesity is on increase since 1971. About 50% of adults are overweight and obese in many countries.

Important features causing obesity:

Obesity occurs when expenditure of energy is less than energy intake of the body. Lifestyle preferences, Environmental factors and cultural environment play important roles in obesity. Genetic factors can also contribute to obesity. Normally, caloric and fat intake are responsible for obesity. Continue reading

Foods containing Omega-3 fatty acid

Omega-3 fatty acids (ω3 fatty acids) are a class of fatty acids playing a key role in lowering cholesterol levels in the body thereby helping in cardiovascular problems. A new study by Indiana University School of Medicine have found that these may also help in treating alcohol abuse and psychiatric disorders.

Researchers have found that fatty acid DHA, which is one of the main active ingredients in fish oil, helps a lot in normalizing the behaviour of mice models of bipolar disorder prepared in the lab of Alexander B. Niculescu, M.D., Ph.D., associate professor of psychiatry and the lead author of the study reported online in the Nature Publishing Group journal Translational Psychiatry. Continue reading
