A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
The metabolism of glucose is the vital process of a living body. In glucose metabolism, glucose plays the most important role in providing the human body the energy required for various other works and for survival as well. Once consumed, glucose is absorbed by the intestines leading to the flow into the blood. Extra glucose that is stored in the muscles and liver as glycogen is hydrolyzed to glucose and released into the blood when needed. Glycogen is mobilized and converted to glucose by gluconeogenesis when the blood glucose concentration is low. Glucose may also be produced from non-carbohydrate precursors, such as pyruvate, amino acids and glycerol, by gluconeogenesis. It is gluconeogenesis that maintains blood glucose concentrations, for example during starvation and intense exercise.
