Amadori compounds (1-amino-1-deoxy-D-fructose derivatives) were prepared by reacting D-glucose with a series of aliphatic amino acids. These include Amadori compounds derived from glycine (1), beta-alanine (2), gamma-amino butyric acid (3), delta-aminovaleric acid (4), epsilon-amino-caproic acid (5)
Ureido 2-deoxy--D-glucopyranosides with seven different amino acid ester residues were studied by means of IR and 1 H NMR spectroscopy. The H-D exchange rates increase in the order L-Val <L-Leu <L-Ala < Gly for both NH protons; however, the exchange rate at N-1-H (linked to the glucopyranoside) is
## Abstract Interest in β‐carbolines has recently increased owing to their detection in human tissue and in some food products; one of the possible sources of their formation in food is the Amadori rearrangement product (ARP) of tryptophan with glucose, l‐[(1′‐carboxy‐2′‐indol‐3′‐ylethyl)amino] ‐1‐
