The most abundant nucleotide in body is
NUCLEOSIDE TRIPHOSPHATE: Corresponding nucleoside di- and tri-phosphates are formed by esterification of fuher phosphate groups to the existing ons. Nucleside diphosphate contains one high energy bond and triphosphates have 2 high energy bonds.ATP is the UNIVERSAL ENERGY CURRENCY. It is formed during oxidative processes by trapping the released energy in the high energy phosphate bond. REF :DM VASUDEVAN TEXTBOOK , 7TH EDITION ; Page no :562.
