Nutritionally Nonessential Amino Acids: A Misnomer in Nutritional Sciences.

A mino acids (AAs) 3 are organic compounds that contain amino and acid groups (1). Based on the configuration of glyceraldehyde (Lor D-isomers as introduced by Emil Fischer in 1908), AAs (except for Gly, taurine, b-alanine, and g-aminobutyrate, which have no asymmetric carbon) exist as either Lor D-AAs. L-AAs are much more abundant than D-AAs in nature and are the physiologic isomers in animal ...

Effects of Supplementing Broiler Diets Low in Crude Protein with Essential and Nonessential Amino Acids

A study was conducted to evaluate the effects of adding all essential amino acids (EAA) equal to that of higher CP diets or a mixture of nonessential amino acids (NEAA) to low CP diets on the live performance of broilers during the period of 0 to 21 d. A series of experimental diets comprised primarily of corn and soybean meal were formulated to contain 3,200 ME kcal/kg. Five primary diets were...

Essential and Non-essential Amino Acids in Neonatal Nutrition

There has been an evolution in the appreciation of the functional roles that amino acids play in neonatal nutrition over the last 30 years. Up to the early 1960s primary interest was in the identification of those amino acids that had to be supplied in the diet in order to maintain growth and positive nitrogen balance (Table 1). Most of the experiments that were performed to identify these amin...

Essential and Non-Essential Amino Acids in Relation to Glutamate

The protein intake during the Palaeolithic period has been estimated to be two and a half fold greater than current recommendations. Hydrogen, nitrogen, oxygen and carbon atoms are important components of essential and nonessential amino acids which are components of proteins. These simple molecules play an important role in the human body. The 22 known amino acids, essential and nonessential, ...
