studied CPEs prepared from amino acids (glycine, β-alanine, alanine, sarcosine, and proline) that were conjugated to hydrophobic chain(s) through a biodegradable ester link [101]. d-proline (d-Pro), glycine (Gly), l-proline (l-Pro), sarcosine (Sar), l-alanine (l-Ala), β-ala...
and mechanism of transport in the majority of cases, while [18F]F-DOPA imaging also visualizes the activity of theenzymearomatic amino acid decarboxylase. A problem of imaging using labeled amino acids can be limited sensitivity since the transporters induce bidirectional exchange of thetracers, othe...

We used decylsulfate (DS) as the anionic transfer agent as negative analogue, to the cationic phase transfer agent DDAB. This co-partitioning allowed for transfer of amino acids and peptides into an oil phase. Proteins and a depsipeptide were also evaluated, but did not rely on the phase ...
To identify the component(s) of RPMI that enabled the growth of parasites deficient in TgNPT1, we prepared a range of ‘hybrid’ media that contained some components (vitamins and amino acids) at concentrations found in RPMI and some at concentrations found in DMEM. Media containing amino acid...
Fig. 2.Structures and biophysical characteristics of MAAs tested in this study or of relevance for discussion in the text.Figure shows chemical structures of the mycosporine-like amino acids, palythine, shinorine, porphyra-334 and mycosporine-glycine. The molecular formula, molecular mass, maximum wa...
are very soluble. However, the hydrochloride salts are also quite acidic in solution, and since they do not exist above about pH 2, they are never used. The basic amino acids, on the other hand, are often used as the hydrochlorides, because they are less acidic and exist at physiological...
