Ile-Leu is a dipeptide formed from L-isoleucine and L-leucine residues. It has a role as a metabolite. It is a tautomer of an Ile-Leu zwitterion. Follow these links to do a live 2D search or …

Branched chain amino acids (BCAAs), including leucine (Leu), isoleucine (Ile), and valine (Val), play critical roles in the regulation of energy homeostasis, nutrition metabolism, gut health, …

Nov 1, 2016 · Despite the great success of mass spectrometry (MS) for de novo protein sequencing, Leu and Ile have been generally considered to be indistinguishable by MS …

'Leu-Ile' refers to a peptide composed of the amino acids leucine and isoleucine, with a total of 27 amino acid residues. You might find these chapters and articles relevant to this topic.

Whereas b and y ions provide adequate mass information to identify most amino acids in peptides, the formation of b and y ions is not sufficient to differentiate leucine (Leu) and …

It is unknown if L-isoleucine (Ile) and L-leucine (Leu) have this same effect. The purpose of this study was to examine how Ile and Leu influence both GLP-1 and GIP, subsequent pancreatic …

This technical note highlights the capability of electron activated dissociation (EAD) for the differentiation of isomeric leucine (Leu) and isoleucine (Ile) residues in biotherapeutics. EAD …

Ile-Leu, Leu-Leu, and Leu-Ile enhance kokumi, while Ile-Ile shows minimal effect. Leu-Leu shows stronger binding with calcium-sensing receptor. Key calcium-sensing receptor residues for …

This study elucidated the kokumi characteristics and underlying differences in Leu- or Ile- containing dipeptides through a comparative analysis of their sensory and molecular properties.

Nov 1, 2022 · In this study, we proposed an accurate and robust Leu/Ile discrimination method based on peptide MS 3 fragmentation. Compared to previous method, continuous digestion …
