# Nucleotide The image presents structural diagrams of nucleotides, specifically focusing on desoxycytidine triphosphate (dCTP) and uridine monophosphate (UMP). **a) Desoxycytidine triphosphate (dCTP)** A diagram of dCTP is shown. It details the components of the molecule: * **Phosphate groups:** The diagram shows three phosphate groups linked together in a chain. * **Base:** A nitrogenous base (likely desoxycytidine). * **Pentose (Sugar):** A five-carbon sugar (likely deoxyribose). Marked by 1', 2', 3', 4', 5' numbering. * **Chemical bonds:** The diagram indicates the phosphoric acid anhydride bonds and other chemical bonds. **b) Uridine monophosphate (UMP)** A similar diagram of UMP is provided. Key components visualized include: * **Phosphate group:** A single phosphate group attached to the sugar. * **Base:** The nitrogenous base uracil. * **Pentose (Sugar):** A five-carbon sugar (likely ribose). Numbered 1',2',3',4',5'. * **Chemical bonds:** The diagram designates the phosphoric ester bonds. **Overall** The image highlights the structural similarities and differences between dCTP and UMP, emphasizing the various components and bonds essential to their function. Different types of bonds are labeled (e.g., β-N-glycosidic). **Additional Information** The caption also includes labels such as "Phosphorsäureanhydrid" (phosphoric acid anhydride), "Phosphorsäure-ester" (phosphoric acid ester), "Pentose", and 'Base". The text also includes the abbreviation for each molecule (dCTP,UMP). The reference "[L253]" likely indicates a source or section within a larger document.
