论文代写：葡萄糖在人体内的代谢过程
是葡萄糖的过程从合成五。这个过程始于丙酮酸。然而,草酰乙酸和二羟丙酮磷酸也可能形成入口点。后获得的乳酸,某些氨基酸蛋白质退化和甘油从脂肪可转化为葡萄糖的糖质新生的过程。它可以被认为是糖酵解的反向过程,尽管某些步骤是不同的。糖质新生的第一步是丙酮酸转换成草酰乙酸。的化合物也与乙酰辅酶a三羧酸循环的反应。净乙酰辅酶a的浓度和细胞内能量(ATP)决定将使用草酰乙酸的途径。低浓度的乙酰辅酶a和高细胞内ATP浓度将触发糖质新生途径。糖质新生的主要部位是肝脏和肾脏皮质。大脑、骨骼肌、心脏肌肉或其他身体组织的网站,非常低的糖质新生发生。这是因为这些器官的葡萄糖的需求非常高。这种代谢途径是不断发生在肝脏维持血糖水平来满足能源需求。
论文代写：葡萄糖在人体内的代谢过程
It is the process by which glucose is synthesised from non-carbohydrate sources. The process begins with pyruvic acid. However, oxaloacetic acid and dihydroxyacetone phosphate may also form entry point. Lactic acid, certain amino acid obtained after protein degradation and glycerol obtained from fat can be converted into glucose by the process of gluconeogenesis. It can be considered as reverse process of glycolysis, though certain steps differ. First step of gluconeogenesis is the conversion of pyruvic acid to oxaloacetic acid. It is the compound that also reacts with acetyl CoA in the citric acid cycle.Net concentration of acetyl CoA and energy level in cells (ATP) determines the pathway in which oxaloacetic acid will be used. Low concentration of acetyl CoA and high ATP concentration in cells will trigger the gluconeogenesis pathway.The main site of gluconeogenesis is liver and cortex of the kidney. Brain, skeletal muscles, heart muscles or other body tissues are the sites where very low rate of gluconeogenesis is known to occur. This is because these organs have a very high demand of glucose. So, it this metabolic pathway is constantly occurring in the liver to maintain blood glucose level to meet energy demands.
