Arginine - definition from Biology-Online.org
[(Science: amino acid) An essential amino acid, a major component of proteins and contains the guanido group that has a pKa of greater than 12, so that it carries a permanent positive charge at physiological ph. It becomes an essential amino acid when the body is under stress or is in an injured state. depressed growth results from lack of dietary arginine. arginine deficiency syndrome is observed in human babies born with a phosphate synthetase deficiency. normal growth and development in these infants are achieved by adding arginine to their diet. arginine deficiency leads to carbamyl phosphate overproduction in the mitochondria due to inadequate ornithine supply. arginine-deficient diets in males causes decreased sperm counts. free and bound arginine are found in abundance in human male sperm and arginine has been found to stimulate sperm motility. there are two sources of arginine, arginine in the food Chain and free-form
