WebMay 27, 1997 · In dA and dG, there is an "N-glycoside" bond between the sugar C1' and N9 of the purine. A nucleotide is a nucleoside with one or more phosphate groups covalently attached to the 3'- and/or 5'-hydroxyl group(s). DNA Backbone. The DNA backbone is a polymer with an alternating sugar-phosphate sequence. Webdisplacement reaction between phosphate and an electrophilic carbon of a nucleoside. To render a carbon electrophilic, the hydroxyl group must be converted into a leaving group of some kind (e.g., a halogen or sulfonate ester). There are two common approaches to convert the 5′-hydroxyl into an electrophile: (1) con- WebApr 4, 2024 · The Carbonyl Group: -CHO. In the carbonyl group, a carbon atom is connected to an oxygen atom with a double bond. Additionally, it has 2 R-groups and the corresponding molecule is referred to as a ketone. If one of the R-groups is a hydrogen atom, meaning the functional group is automatically terminal, this is known as an aldehyde group. clip and pin hk lower
