Amino acids stimulate cell growth and development cellular. Polyamines are the integrated part of the cellular and genetic metabolism and help in transcription, translocation, signaling and post-translational modications. Polyamines binding to RNA leads to structural changes which stimulate and increase the protein synthesis along the amino acids may inuence the conditions of various diseases. Several diseases can be controlled to a higher extend via maintaining the metabolism of amino acids and polyamines. On the other hand, a controlled diet is a way to maintain the level of amino acids and polyamines in the body. Present review highlights to etiology of cancer, also discusses functions and metabolism of polyamines in human and also highlights the nutritional role of amino acids and polyamines in the prevention and control of various diseases.
