In a recent study, scientists found that insulin is an evolutionary but a closed street. It performs its ability to adapt to obesity and thus most people are susceptible to type 2 diabetes.
According to a study by Indiana University School of Medicine, University of Michigan, and Case Western Reserve University scientists, the sequence of insulin is impaired. There is an intrinsic weakness by rare mutations in childhood diabetes-causing insulin genes. Most people are vulnerable to type 2 diabetes.
This study deals with the emerging field of evolutionary medicine related to biophysical concepts and protein chemistry. Insulin is produced by a series of highly specialized processes occurring in specialized cells, called beta cells. The study has been published in Proceedings of the National Academy of Sciences.
