Thiol amino acids in proteins store metals like mercury, but established methods for their
quantitation in freshwater species have had limited application and evaluation. As such …

We examined the performance of an ultra-high performance liquid chromatography method
to quantify protein-bound sulphur amino acids in zooplankton. Both cysteic acid and …

Amino acids are essential building blocks of life. A number of mechanisms are responsible
for the presence of amino acids in seawater, including direct release by phytoplankton via …

Although the amino acid composition of fishes and some marine invertebrates varies among
taxa and systems, similar information is lacking for freshwater invertebrates. The objectives …

Abstract A UHPLC-HILIC-tandem MS method has been developed and validated for the
quantification of 21 amino acids (20 protein amino acids and cystine) in their free form (FAA) …

An amino acid analyzer method for the simultaneous determination of 20 free amino acids
(FAAs) and glutathione (GSH) in Penaeus vannamei (PV), Penaeus vannamei, Penaeus …

Dissolved combined amino acids (DCAA) are important constituents of the dissolved organic
nitrogen (DON) pool in marine environments, although little is known about their sources …

Four methods were evaluated for estimating the proportion of dissolved free amino acids
(DFAAs) metabolized by sulfate‐reducing bacteria (SRB). Our main aim was to assess the …

Improved methodology for amino acid analysis coupled with semi-micro isolation techniques
make feasible the measurement of individual amino acids from marine waters where sample …
