lactate metabolic process
Definition
Target type: biologicalprocess
The chemical reactions and pathways involving lactate, the anion of lactic acid. [ISBN:0198547684]
Lactate metabolism is a crucial process in cellular energy production and homeostasis. It involves the conversion of pyruvate, a key molecule in cellular respiration, to lactate under conditions of low oxygen availability, such as during intense physical activity. This process, known as anaerobic glycolysis, allows for the continued production of ATP, the primary energy currency of the cell, even in the absence of sufficient oxygen.
Lactate production occurs primarily in skeletal muscle, red blood cells, and the brain, where it serves as a temporary energy source. During strenuous exercise, muscle cells switch to anaerobic glycolysis, generating lactate as a byproduct. This lactate can then be transported to other tissues, such as the liver, where it can be converted back to glucose through the Cori cycle.
Lactate metabolism is also important in maintaining cellular pH balance. During glycolysis, hydrogen ions are released, potentially leading to acidification of the intracellular environment. Lactate production helps buffer these protons, preventing a significant drop in pH.
In addition to its role in energy production and pH regulation, lactate has emerging functions in cell signaling and immune response. It can act as a signaling molecule, modulating gene expression and influencing cellular processes. Additionally, lactate can be utilized by immune cells as an energy source and may play a role in immune regulation.
The lactate metabolic process is a complex and multifaceted pathway with vital roles in cellular energy production, pH homeostasis, and potentially, cell signaling and immune function. Understanding this process is crucial for comprehending cellular metabolism, exercise physiology, and various disease states.'
