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 ...

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

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

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

Overview on L-asparagine monohydrate single crystal: A non-essential amino acid

Journal of Nonlinear Optical Physics & Materials, 2022
This paper reviews the growth and properties of L-asparagine monohydrate (L-ASPM) single crystal. The growth technique by which a well-defined bulk-sized single crystal can be grown is also reported. The various reported studies done over titled crystal signify its suitability for various optoelectronic applications.

Ingested non-essential amino acids recruit brain orexin cells to suppress eating in mice

Current Biology, 2022
Ingested nutrients are proposed to control mammalian behavior by modulating the activity of hypothalamic orexin/hypocretin neurons (HONs). Previous in vitro studies showed that nutrients ubiquitous in mammalian diets, such as non-essential amino acids (AAs) and glucose, modulate HONs in distinct ways.

Non-essential amino acids and short-term food intake of rats

Nutrition Research, 1994
Abstract The objective of these studies was to evaluate the role of the six non-essential amino acids (NEAA) found in egg albumin, either in groups or individually on food intake of rats fed a 25% casein defined diet. Compared to control (water), 1.5g of a complete NEAA mixture given by gavage caused significant suppression in food intake by 70, 75 ...

Essentiality of non-essential amino acids for tumour cells and tumorigenesis

Nature Metabolism, 2019
In this issue, Diehl et al. report that exogenous serine is essential for the cellular redox state and cancer nucleotide production, despite the ability of cancer cells to synthesize serine de novo in vitro.
