There are a large number of acids in our body, most common of which are nucleic acids, gastric acid and amino acids. The nucleic acids exist in the form of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA carries all the genetic information and RNA is responsible for transferring the genetic code and protein synthesis. Thus, these acids are not only the blueprint of the cell, they also synthesize protein necessary for maintenance, growth, metabolism, etc. Gastric acid, consisting mainly of hydrochloric acid, are produced in our stomach and have a pH of 1.5 to 3.5. Gastric acid is necessary for breakdown and digestion of proteins. Amino acids are necessary for synthesis of proteins (by forming peptide bonds) and they also carry out other functions in our body.
Hope this helps.
