THE BIOCHEMISTRY AND PHYSIOLOGY OF NUCLEOTIDES

Nucleotides are phosphate esters of nucleosides that contain a sugar l inked through a glycosidic linkage with purine and pyrimidine bases. P urine and pyrimidine nucleotides are major components of the cells tha t make up the monomeric units of DNA and RNA, and they function in all cellular processes. Biosynthesis, interconversion, catabolism and oth er aspects of nucleotide metabolism, along with various cellular roles of nucleotides, will be discussed, and the possible use of dietary so urces of preformed purines and pyrimidines wilt be considered.
