Question
Is the sugar in the nucleotide deoxytibose or ribose? How do you know?
The image shows the chemical structure of a nucleotide, specifically adenosine monophosphate (AMP). This molecule is a fundamental building block of nucleic acids, such as DNA and RNA. ### Structure Description: 1. **Phosphate Group**: - Located on the left side of the molecule. - It is represented as a phosphate (PO₄) group with a negative charge, indicated by "O⁻". 2. **Pentose Sugar**: - Attached to the phosphate group is a five-carbon sugar (ribose). - The sugar ring contains an oxygen atom and several hydroxyl (OH) groups, indicating its ribose nature. - Hydrogen atoms are represented by "H". 3. **Adenine Base**: - Attached to the pentose sugar is a nitrogenous base, adenine. - Adenine consists of a double-ring structure known as a purine. - It contains nitrogen atoms ("N") and an amino group ("NH₂") attached. This compound plays a crucial role in energy transfer and cellular signaling.
