Nucleotides are important components that make up the genetic material of the human body. Nucleotides are involved in the synthesis of DNA and RNA, which in turn make up the entire genome of the human body and constitute the body’s chromosomes. These genetic materials carry all the genetic information of the human body, including external appearance, body shape, as well as internal tissues and organs, physiological and psychological characteristics in many aspects. Nucleotides also make up adenosine triphosphate, which is an important substance that supplies the body with energy and is involved in the metabolism of many types of energy. A lack of nucleotides in the human body may lead to a lack of energy and damage to organs, muscles and cells, which should be supplemented with exogenous sources.
