Guanosine Triphosphate (GTP) is a nucleotide that plays a crucial role in cellular processes. It consists of a guanine base, a ribose sugar, and three phosphate groups. GTP is similar to Adenosine Triphosphate (ATP) and serves as an energy source for various biochemical reactions, including protein synthesis and signal transduction. In addition to its energy-carrying function, GTP is essential for the synthesis of RNA and the activation of certain proteins. It acts as a signaling molecule in pathways that regulate cell growth and differentiation, making it vital for maintaining cellular functions and overall health.
