Non-essential amino acid sources in crystalline amino acid diets for trout (Oncorhynchus mykiss)
Journal of Applied Ichthyology, 1995A 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

Essentiality of non-essential amino acids for tumour cells and tumorigenesis
Nature Metabolism, 2019In 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.

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

Abstract The cerebral influx rates of fifteen amino acids were measured directly in living rats by means of a new technique which makes it possible to maintain a constant specific activity of a radioactively labelled amino acid in the bloodstream. A wide variation in the influx rates of the amino acids was found.

The intake of dietary protein regulates growth, metabolism, fecundity and lifespan across various species, which makes amino acid (AA)-sensing vital for adaptation to the nutritional environment. The general control nonderepressible 2 (GCN2)-activating transcription factor 4 (ATF4) pathway and the mechanistic target of rapamycin complex 1 (mTORC1 ...

Non-essential amino acids and short-term food intake of rats
Nutrition Research, 1994Abstract 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 ...

SummaryThree experiments were carried out on 2 lactating goats, in which mammary arterial plasma amino-acid concentrations were elevated by the infusion of a solution of non-essential amino acids into a carotid artery supplying a transplanted mammary gland. In a fourth experiment a solution of glucose was similarly infused.

The intestinal absorption of some essential and non-essential amino acids in fed and fasting rats
Life Sciences, 1970Abstract 1. 1. The absorption of a number of essential (methionine, leucine and histidine) and non-essential amino acids (glycine, proline, alanine and 2-amino isobutyric acid) from low (5mM) and high (30mM) luminal concentrations was measured in vivo in fed and 3-day fasted rats and compared using two parameters, absolute amount absorbed ...
