ESSENTIAL AMINO ACIDS IN MICROORGANISMS

Canadian Journal of Microbiology, 1957
The cells of 19 species of bacteria, actinomyces, and yeasts were analyzed for protein and essential amino acids. A rapid quantitative method for amino acid determination using one-dimensional paper chromatography was developed. The cellular protein from all species contained relatively high concentrations of lysine, somewhat lower concentrations of ...

Glutamine: An Essential Amino Acid for the Gut

Nutrition, 1996
Glutamine is a non-essential amino acid which is produced in sufficient amount by the healthy human body. From experimental work it is known that glutamine is an important nutrient for rapidly dividing cells such as cells from the immune system and the gut. During several conditions a lack of glutamine may occur.

Arginine: An Essential Amino Acid for the Cat

The Journal of Nutrition, 1978
The essentiality of arginine for the near-adult cat was demonstrated in three preliminary and two main experiments. In the pre liminary experiments, changing cats (body weights all in excess of 1.6 kg) from a purified diet containing a complete amino acid mixture (basal) to a similar isonitrogenous diet without arginine ( —Arg) caused rapid loss of ...

Essentiality of Amino Acids for the Growing Kitten

The Journal of Nutrition, 1979
The effect of deleting each of the amino acids known to be essential for the young rat was determined in post weanling kittens fed a purified diet containing only L-amino acids as the source of dietary nitrogen. When any one of the 10 amino acids (arginine, lysine, histidine, isoleucine, leucine, methionine, phenylalanine, threonine, tryptophan, valine)

Is Glutamine a Conditionally Essential Amino Acid?

Nutrition Reviews, 2009
The nonessential amino acid glutamine has recently been the focus of extensive scientific interest because of its importance in cell and tissue cultures and its physiologic role in animals and humans. Glutamine appears to be a unique amino acid, serving as a preferred respiratory fuel for rapidly proliferating cells, such as enterocytes and lymphocytes;

ADEQUACY OF THE ESSENTIAL AMINO ACIDS FOR GROWTH OF THE RAT

Science, 1944
Growth was obtained in rats on synthetic diets in which the ten essential amino acids were the sole source of amino acid nitrogen. The growth rate was dependent upon the quantity of amino acids fed and appeared to compare favorably with that obtained when a similar quantity of nitrogen was fed in the form of casein.

Neoaplectana glaseri: Essential amino acids

Experimental Parasitology, 1973
Abstract Required for a nematode's reproduction in a chemically defined medium are the nine mammalian essential amino acids ( sensu strictu ). Needed in addition to lysine, tryptophane, histidine, phenylalanine, leucine, isoleucine, threonine, methionine, and valine is arginine which is marginally essential for mammals.

Essential Dietary Amino Acids

American Journal of Diseases of Children, 1961
The studies, The Essential Amino Acid Requirements of Infants , by Synderman et al. 1,2 may seem of remote value in the "practical" everyday feeding of infants. Yet these studies, and numerous similar ones by others, are significant contributions to the science of nutrition. Holt et al.
