A Simplified High-Performance Liquid Chromatographic Method For Determination of Vitamin D3 in Human Serum
Abstract: Diabetes is a metabolic disorder caused by defective insulin secretion, insulin action or both. The two major factors for the development of diabetes are pancreatic beta cell dysfunction and insulin resistance. In type 2 diabetes mellitus, production and release of insulin is unobstructed but due to factors like ageing or obesity, the produced insulin cannot compensate for the increased demand. Measurement of the serum level of 25-hydroxyvitamin D3 is the …
