Nucleotide is a monomer (repeating small unit) of DNA, RNA. It also constitutes ATPs, GTPs, ADPs and so on. Nucleotde consists of a sugar pentose, nitrogen base and and phosphate group. Sugar can be either ribose or deoxyribose (note that deoxyribose is sugar, but not a carbohydrate). Nitrogen base can be either derivative of pyrimidine - a heterocycle ring - which are Thymine, Cytosine and uracile; or purine rings - two heterocycle rings joined together - which are guanine and adenine. Nitrogenous bases are attached to 1'-carbon atom in the sugar. Phospate group is attached to the 5' carbon via phosphoester bond. That's all, mi amigo. Qosh bol
Plants store the energy of Sunlight in the chemical bonds of Glucose. During photosynthesis, green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen using light energy that is trapped by chlorophyll.
