Abstract: This paper describes the effect of dietary nucleotides on the gastrointestinal tract in infants, the absorption and metabolism of nucleotides in the body, and makes a comparison of the nucleotide content of human milk and cow’s milk. Compared to breast milk, the contents of nucleotides and their derivatives in cow’s milk is lower, and can not meet an infant's nutritional requirements.
