1, D-Alanine fons chiralis organici magni momenti est, adhibetur in medicina chirali, additivis chiralibus, et est fons chiralis synthesis chiralis in pharmaceutica et cibi industria.Ut unum acidum organicum cum activitate optica, D-Alanine munus irreparabile in chymicis quibusdam compositionibus asymmetricis compositionis seriei chiralis habet.Nunc autem D-Alanine novum spectri genus fabricare, D-Alaninol et Alitame novam suavitatem componit.
2, D-Alanine necessaria est metabolismi cellae et in corpore excessus nutrienti.
3, D-Alanine involvit cyclum glucose-alanini inter fibras et iecur.
4, D-Alanine adhibetur materia rudis ad synthesin novarum dulcedariorum et intermediorum medicamentorum chiralium.
V, D-Alanine maxime adhibetur ad componendum acidum pantothenicum et calcium pantothenatum, carnosinum, pamidronatum, balsalazidam, etc., et late in medicina, cibo, cibo et aliis agris adhibetur.Adhibetur etiam in corrosionibus inhibitoribus et diameticis reagentibus electroplatis.
VI, D-Alanine maxime adhibetur ut supplementum nutritionis et CONDITIO in cibo processus industriae.Potest etiam adhiberi in industria medicinae.
7. D-Alanine bonam viriditatem habet et effectus saporum chemicorum promovere potest;Suavitatem peculiarem habet et saporem mellificiorum artificialium emendare, acrem organicorum acida et aceti saporem emendare;Acria eius adiuvare potest salem olera inire, qualitatem salsarum vel condimentum condimentorum olera emendare, salsamentum temporis interscindere et saporem emendare;
8. D-Alanine adhiberi potest corrector vel quiddam in compositione vini vel potus mollis, potest ne bullire vinum senescit et odorem fermenti minui possit;
9. Munus eius antioxidationis in processus cibi adhiberi potest.Exempli causa, adhiberi potest in oleis, vitellis impedita, cibis purgatis, liquaminibus, ac salsamentis.Potest et eas ab oxidatione tueri et saporem suum emendare;
10. D-Alanine adhiberi potest ut materia rudis Vitaminum B6 synthesis et materia investigationis de metabolismo amino acidorum per organismos medicorum vel in fundamento biochemico.
