The effects of ?-lactalbumin and whey protein concentrate on ?-amino acids, calciumand phosphorus levels in blood and gastrointestinal tract of rats
Bibliographic record
Abstract
The effects of two dietary proteins on α-amino acids, calcium and phosphorus concentrations in plasma, stomach and intestine were investigated in rats trained to consume, in a single two-hour daily meal, diets containing α-lactalbumin (α-la) or whey protein concentrate (WPC) for two weeks.The results indicated that the concentrations of calcium and phosphorus in the gastrointestinal tract and that of α-amino acids in portal vein were not significantly influenced by the nature of diets.The amount of α-amino acids in the gastrointestinal tract of rats fed on WPC diet was significantly (p < 0.001) higher than that of α-la group.The levels of insoluble calcium and insoluble phosphorus in the small intestine were significantly (p < 0.001) higher in α-la group than in WPC group.These results indicated that the kinetics of α-amino acids, calcium and phosphorus were differently influenced by the nature of diet ingested, the sampling time and the sites of sample collections.α-lactalbumin / whey protein / α-amino acid / calcium phosphorus / digestion Résumé -Effets de l'α-lactalbumine et d'un concentré de lactosérum sur les teneurs en acides α-aminés, en calcium et en phosphore dans le plasma et le tube digestif chez les rats.Les effets de protéines alimentaires sur les teneurs en acides α-aminés, en calcium et en phosphore dans le plasma et le tube digestif ont été étudiés chez des rats alimentés pendant deux semaines selon des régimes contenant de l'α-lactalbumine (α-la) ou un concentré de lactosérum (WPC).Les concentrations de calcium et de phosphore solubles dans le tube digestif et celles des acides α-aminés dans la veine porte, étaient comparables pour les deux groupes étudiés.En revanche, la quantité d'acides α-aminés dans le tube digestif des rats du groupe WPC était significativement (p < 0,001) supérieure.Les niveaux de calcium et de phosphore insoluble dans le tube digestif des rats du groupe α-la étaient significativement (p < 0,001) plus élevés.Ces résultats montrent que les profils des acides α-aminés, du calcium et du phosphore solubles dans le tube digestif étaient différemment influencés par la nature protéique du régime ingéré, le temps et les sites d'échantillonnage.α-lactalbumine / protéines de lactosérum / acide α-aminé / calcium / phosphore

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
