The main metabolic pathways following glucose into mammalian cells are shown in Fie. 1. From the quantitative point of view, the most important route is also called Embden Meyerhof glycolytic pathway. Under anaerobic conditions, the final product of glycolysis is lactic acid, while in the presence of oxygen, pyruvic acid enters the citric acid cycle to be oxidized to CO2 and water. However, some tumors and normal tissues, among which are the brain, are still significant amounts of lactic acid under aerobic conditions. Glycolysis and respiration are major mechanisms in the energy-producing mammalian cells.

The liver problems in pregnancy has been a constant concern for researchers, but the literature review leads to non-uniform morphological studies and fragmentary functional scans.

Universidad Nacional Mayor de San Marcos’ Emeritus Professor Dr. Marino Villavicencio Nuñez narrates in this article his personal experiences starting with early teaching steps as partial time Training chief and facts that traced his formation and national and international acknowledgement as one of the most outstanding researchers in biochemistry. Dr. Villavicencio is part and the manager of Biochemistry and Nutrition Research Center’s history. Nobody could relate better laboratories’ organization details, equipment, staff capacitation, and the highest level scientific production that lead our institution to be considered as an excellency biochemistry center in Latin America. Dr. Marino Villavicencio is an authentic Master and even though he ceased with 37 years of professional services he continues teaching us through his books on biochemistry, his up to date biochemistry digest...
