Deoxyguanosine
Deoxyguanosine is a purine nucleoside which is composed of the purine base guanine attached to the sugar deoxyribose. It is a component of DNA and plays a crucial role in genetics and cell biology.
Structure and Properties[edit | edit source]
Deoxyguanosine is composed of a guanine base attached to a deoxyribose sugar. The guanine base is a purine, consisting of a six-membered ring fused to a five-membered ring. The deoxyribose sugar is a pentose sugar, and it lacks one oxygen atom compared to ribose, hence the name "deoxy".
Role in DNA[edit | edit source]
In DNA, deoxyguanosine pairs with deoxycytidine through three hydrogen bonds. This pairing is crucial for the structure of the DNA double helix and for the accurate replication of DNA during cell division.
Clinical Significance[edit | edit source]
Abnormal levels of deoxyguanosine can be indicative of certain medical conditions. For example, elevated levels of deoxyguanosine can be seen in Purine nucleoside phosphorylase deficiency, a rare genetic disorder that affects the immune system.
