Nucleotide triphosphates (NTPs) are organic molecules that serve as the building blocks of nucleic acids, such as DNA and RNA. Each NTP consists of a nitrogenous base, a sugar molecule, and three phosphate groups. The three phosphate groups are key to their energy-carrying capabilities, as they can release energy when bonds between them are broken. In cellular processes, NTPs play a crucial role in energy transfer and storage. For example, ATP (adenosine triphosphate) is the most well-known NTP, providing energy for various biochemical reactions, including protein synthesis and cellular respiration. Other NTPs, like GTP and CTP, also have specific functions in cellular metabolism and signaling.
