Adenosine Monophosphate (AMP) is a nucleotide that plays a crucial role in cellular energy transfer. It consists of an adenosine molecule attached to a single phosphate group. AMP is involved in various biochemical processes, including the synthesis of ATP (adenosine triphosphate), which is the primary energy carrier in cells. In addition to its role in energy metabolism, AMP acts as a signaling molecule in cells. It can activate AMP-activated protein kinase (AMPK), an important regulator of energy balance, which helps maintain cellular energy homeostasis and influences metabolic pathways.
