Mechanochemical and mass spectral approach for the analysis of maltosylated glycylglycine
Bibliographic record
Abstract
The interaction of maltose with glycylglycine was studied under ball milling condition to generate the Amadori product. Although single step milling (30 Hz, 30 min) has been shown to be efficient in the generation of Amadori products of monosaccharides with amino acids, however with disaccharides and dipeptides, single step process showed a significant intensity of unreacted disaccharide peak, prompting us to develop a multistep process where the more consumed reactant was replenished in the subsequent milling steps. Under multistep milling conditions, the Amadori compound was the main product. The fragmentation patterns of protonated and sodiated Amadori products were studied aided by isotope labeling technique. Formation of the other products in the ball-milled maltose and glycylglycine was rationalized through glycosidic and peptidyl bond cleavage reactions. Degradation of the Amadori product of maltose and glycylglycine through such cleavage reactions, generated three other Amadori products corresponding to dipeptide/monosaccharide, amino acid/monosaccharide and amino acid/disaccharide interactions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
