Amino Acid Testing

Sidebar Image

Amino acids are the building blocks of proteins and therefore a vital part of the diet.  Several of the amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) cannot be produced by the human body and are therefore considered “essential”.  A lack of any of the essential amino acids in the diet can lead to poor health and death.  In addition, what constitutes essential amino acids can vary. For example, cats cannot synthesize taurine and lack of taurine causes eye-problems, hair loss and tooth decay. For that reason, amino acid testing is important to determine the quality of protein in food, pet food, and animal feeds. 

Eurofins is the leader in amino acid analysis offering a variety of methods that can quickly and accurately quantify the amino acids present of almost any sample.
