In this study, we investigated as to what extent modified amino acids are released from post-translationally modified casein during simulated gastrointestinal digestion. Casein was enriched with N-ε-fructoselysine, N-ε-carboxymethyllysine, and lysinoalanine, in different degrees of modification. The ...
Via GC-EI-MS and GC-CI-MS, the use of deuterated ketoximes assists in the unambiguous identification of common fructosyl-amino acids found in fruits and provides a means for their quantitation as their per-O-TMS derivatives of n-butyl(d_n)-ketoximes. Characteristic fragment ions by EI that...
Fructosyl-amino acids (FAA, also known as Amadori compounds) form naturally in many foods when dehydrated or during food processing and are of key interests in both nutrition and drug design. Gas-liquid chromatography / mass spectrometry (GLC/MS) investigations have indicated that analysis of FAA...

AMINO SUGARS/chemistryANILINE COMPOUNDS/chemistrySUCROSE/chemistryThe physiological activity of complete series of mono- and di-substituted chloro-and methyl-phenoxyacetic and benzoic acids have been investigated using the wheat cylinder, pea segment and pea curvature tests. In the phenoxyacetic acids, ...
For some time we were intrigued by an unknown compound appearing on amino acidschromatograms of urine from patients receiving a lactose free evaporated milk in which lactose had been replaced by glucose. The unknown substance was isolated by ionexchange chromatography and identified as-/1-deoxy...
