Dietary requirements of “nutritionally non-essential amino acids” by animals and humans

Amino Acids, 2012
Amino acids are necessary for the survival, growth, development, reproduction and health of all organisms. They were traditionally classified as nutritionally essential or non-essential for mammals, birds and fish based on nitrogen balance or growth. It was assumed that all "non-essential amino acids (NEAA)" were synthesized sufficiently in the body to

IMBALANCE OF NON-ESSENTIAL AMINO ACIDS AND CELL GROWTH.

Experimental Cell Research, 1963
Abstract The effect of amino acid imbalances on cell culture growth has been studied. With an essential amino acid, tryptophane, the l -isomer is more inhibitory for HeLa cell growth. Serine, a non-essential amino acid, was more inhibitory in the d -configuration than in the l for HeLa cells, but the isomers were equally effective for ascites H ...

THE NUTRITIVE EFFECT IN MAN OF NON‐ESSENTIAL AMINO ACIDS INFUSED INTRAVENOUSLY (TOGETHER WITH THE ESSENTIAL ONES)

Acta Anaesthesiologica Scandinavica, 1970
SUMMARYSolutions containing one of the amino acids 1‐alanine, 1‐arginine, glycine, 1‐histidine, 1‐proline or 1‐glutamic acid and a basic mixture of the essential 1‐amino acids and 1‐arginine and 1‐histidine were infused intravenously to healthy volunteers on a nitrogen‐poor diet. The nitrogen balance and die excretion of urea, ammonia, a‐amino nitrogen

Arsenic affects essential and non-essential amino acids differentially in rice grains: inadequacy of amino acids in rice based diet.

Environment International, 2012
Recent breakthroughs in rice arsenic (As) research demonstrate that As accumulation significantly affects trace nutrients in rice grain. In the present study we analyzed the amino acid (AA) profile of sixteen rice genotypes differing in grain As accumulation, grown at three sites with different soil As concentrations, in ascending order ...

Goblet cells and mucus layer in the gut of young pigs: Response to dietary contents of threonine and non-essential amino acids.

Journal of animal physiology and animal nutrition, 2019
Mucins secreted by goblet cells (GC) are the major components of mucus layer coating and protecting gut epithelium. The study aimed at determining the effect of non-essential amino acids (NEAA) and threonine (Thr) levels on GC number and mucus layer ...

Non-essential amino acid sources in crystalline amino acid diets for trout (Oncorhynchus mykiss)

Journal of Applied Ichthyology, 1995
A study was conducted over a 84-day period to evaluate glycine, L-glutamic acid and L-glutamine as sources of non-essential amino acids (NEAA) in dietary ‘protein’ consisting of crystalline amino acids only. The study was performed with a total of 1200 rainbow trout fingerlings (Oncorhynchus mykiss) of 48 g mean body mass. The addition of non-essential

Influence of essential and non‐essential amino acids on calcium oxalate crystallization

Crystal Research and Technology, 2010
AbstractThe investigation on the mechanism of nucleation and growth of crystals at organic‐inorganic interfaces is crucial for understanding biological and physiological calcification processes such as the formation of urinary stones. The effects of five different amino acids on the crystallization of calcium oxalate have been investigated at pH 4.5 ...
