This block is dedicated primarily to the central routes of metabolism that are shared by most living organisms. The units frame the routes thatwill be studied within global patterns of metabolism and highlight the objectives and general aspects, before a detailed examination of the reactions. Within this analysis, we mainly study the chemical transformation that takes place, and energetical aspects of it. It is important to emphasize the interconnection of different routes and their coordinated regulation. After a This unit is the study of the central metabolic pathways shared by most living organisms.
Highlight the objectives and general aspects, before proceeding to the detailed analysis of the reactions. In this analysis, we studied the chemical conversion mainly takes place and energy aspects of the same. Importantly, the interconnection of the various routes and their coordinated regulation.
After a theme that provides an overview of metabolism.
The (1) carbohydrate metabolism study of acetyl-CoA and the citric acid cycle, the study of the route of the pentose phosphate, photosynthetic CO2 assimilation is studied, with the study of glycolysis-gluconeogenesis, and glycogen metabolism.
(2) Metabolism of simple lipids such as fatty acids, and complex lipids such as triacylglycerols, phosphoglycerides and sphingolipids. Cholesterol precursor functions are also discussed in the biosynthesis of steroid hormones and bile salts.
(3) Metabolism of nitrogen compounds in the study of oxidative degradation of the amino acids, which is divided into two parts: the destination of the nitrogen and the carbon skeletons. The nitrogen cycle in the biosphere and biological fixation of atmospheric nitrogen by nitrogenase is presented. Metabolism of purine nucleotides and pyrimidine is studied that all living beings are able to synthesize. Finally an integrated vision of intermediary metabolism and its control is intended.unit that provides an overview of metabolism, we have followed the traditional order in the study:(1) metabolism of carbohydrates, the study of glycolysis-gluconeogenesis, the study of acetyl-CoA and citrus acid cycle, the study of the route of the pentose phosphates, photosynthetic CO2 assimilation, and metabolism of glycogen. (2) simple lipid metabolism, as fatty acids, and more complex lipids such as triglycerides, phosphoglycerides and sphingolipids. It also addresses the functions of cholesterol precursors in the biosynthesis of bile salts and steroid hormones. (3) Metabolism of nitrogen compounds, with the study of oxidative degradation of amino acids, which is divided into two parts: the fate of nitrogen and the carbon skeletons. We describe the nitrogen cycle in the biosphere and biological fixation of atmospheric nitrogen by nitrogenase. We study the metabolism of purine and pyrimidine nucleotides that all living beings are capable of synthesizing. Finally, it seeks a comprehensive view of intermediary metabolism and its control.
