This chapter discusses the role of enzymes in carbohydrate metabolism and related biological processes. The chapter discusses how a number of enzymes can act together to carry out an integrated and complicated process. In an intact biological system there are several ways in which the reduced ...
What are allosteric enzymes? Where can enzymes function in the body? Which statement accurately describes the function of enzymes? What are some examples of biological processes in which lysosomal enzymes play a fundamental role? (a) What are enzymes? (b) What are they for?
structure analysis began in the early 2000s and advances in our understanding of the structure-activity relationships, based on interactions with this target within the mevalonate pathway and related enzymes in osteoclasts and other cells have continued to be the focus of research efforts to this ...
Lysosomes are an important component of the inner membrane system and participate in numerous cell biological processes, such as macromolecular degradation, antigen presentation, intracellular pathogen destruction, plasma membrane repair, exosome release, cell adhesion/migration and apoptosis. Thus, lysosomes ...

Molecular recognition is central to all biological processes. For the past 50 years, Koshland's 'induced fit' hypothesis has been the textbook explanation for molecular recognition events. However, recent experimental evidence supports an alternative mechanism. 'Conformational selection' postulates that all...
Morphological changes observed in OA include cartilage erosion as well as a variable degree of synovial inflammation. Current research attributes these changes to a complex network of biochemical factors, including proteolytic enzymes, that lead to a breakdown of the cartilage macromolecules. Cytokines suc...
in the differentiation of various cells, including bone cells, neurons, cardiomyocytes, and blood cells.16,17,18,19,20Recently, several epigenetic mechanisms in response to extracellular factors have been shown to play a critical role in the control of gene expressions during neurogenesis.21,22,23...
In relation to antioxidant defenses, trypanothione pathway plays a crucial role, being a peculiar thiol-redox system responsible for the maintenance of protozoa functions mediated by thiol-dependent processes. In this chapter, we discuss the biological aspects of oxidative stress in trypanosomatids and ...
