An Evaluation of the Arginine Requirements of Broiler Chickens and the Potential Arginine and Energy-Saving Effects of Guanidinoacetic Acid

open access: yesAnimals
Two 35-day trials were conducted to determine the arginine (Arg) requirement of broiler chickens and the Arg and energy-sparing effects of guanidinoacetic acid (GAA). In experiment 1, a low-Arg diet (basal diet) was supplemented with increasing levels (0.

Gut amino acid absorption in humans: Concepts and relevance for postprandial metabolism

open access: yesClinical Nutrition Open Science, 2021
Summary: Dietary amino acid absorption kinetics are an important determinant of protein quality. The term “amino acid digestibility” is commonly used to refer to the amount of ingested amino acids that become available following absorption.

New aspects of amino acid metabolism in cancer

open access: yesBritish Journal of Cancer, 2019
An abundant supply of amino acids is important for cancers to sustain their proliferative drive. Alongside their direct role as substrates for protein synthesis, they can have roles in energy generation, driving the synthesis of nucleosides and ...

Cloning and sequence analysis of cDNAs encoding the cytosolic precursors of subunits GapA and GapB of chloroplast glyceraldehyde-3-phosphate dehydrogenase from pea and spinach [PDF]

open access: yes, 1989
Chloroplast glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is composed of two different subunits, GapA and GapB. cDNA clones containing the entire coding sequences of the cytosolic precursors for GapA from pea and for GapB from pea and spinach have ...

Research Progress of Amino Acid Metabolism PET Imaging in Tumor

open access: yesJournal of Isotopes, 2015
Amino acid metabolism PET imaging plays a very important role in metabolism molecular imaging. Amino acid PET tracers include [1-11C]amino acid, labeling α-C amino acid, labeling side-chain amino acid, and N-substituted labeling amino acid.

Amino acid neurotransmitters in the CNS

open access: yesFEBS Letters, 1986
D‐Aspartate exchange, defined as amino acid‐stimulated D‐[3H]aspartate efflux, was investigated in a preparation of rat brain synaptosomes. The efflux of radiolabelled D‐aspartate was found to be enhanced by micromolar concentrations of externally added D‐ and L‐aspartate, L‐glutamate, L‐cysteate.and L‐cysteinesulphinate.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]

open access: yes, 2015
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

open access: yesFEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.
