Chemical Properties	Acidum L-malicum fere inodorum ( interdum odoris languidi , acrei).Compositum hoc saporem acerbum, acidicum, non pungentem habet.
Chemical Properties	patet hyalina solution
Eventum	Occurrit in acerno succo, pomo, cucume, papaya, cerevisia, vino, cocco, gralia, kiwifruit et cichoria radice.
usus	Acidum L-malicum pro cibo additivo adhibetur, selectivum α-amino gerens amino acidi derivata tutans.Synthon versatilis ad praeparationem compositorum chiralium inclusis receptantis κ-opioidei agonistae, 1α, 25-dihydroxyvitamin D3 analogi, et phoslactomycin B.
usus	Isomer naturaliter occurrens est forma L-quae inventa est in pomis et multis aliis fructibus et plantis.Selectivum α-amino gerens amino acidi derivata tutans.Synthon versatilis ad compositorum chiralium parandos quos possidet κ-opioids rece
usus	Media in synthesi chemica.Cheating and buffering agent.Agens sapidum, sapor augens et acidulans in cibis.
Definition	ChEBI: Acidum malicum optically forma activa habens (S) -configuration.
Praeparatio	Acidum L-malicum praeparari potest ex hydratione acidi maleici;a fermentum iaculis.
Communia	Acidum L-malicum est acidum organicum quod in vino vulgo invenitur.Magni ponderis munus in vino microbiologico stabilitatis agit.
Biochem/physiol Actiones	Acidum L-malicum pars metabolismi cellulosi est.Eius applicatio in pharmaceuticis agnoscitur.Utile est in curatione confusi hepatisci, efficax contra hyper-ammonamiam.Ponitur amino pars infusionis acidi.Acidum L-Malicum etiam nanomedicinum inservit in curatione morborum neurologicorum cerebri.A TCA (Krebs cyclus) intermedius et particeps in acidi malici pectine aspartatis.
Purificationis Methodi	Crystallize acidum S-malicum (carbo) ex ethyl acetate/pet aethere (b 55-56o), temperatura infra 65o servans.Vel dissolve illud refluendo in quindecim partibus aetheris anhydri diethyi, decanti, conducunt ad tertiam volumen et crystallize illud in 0o, saepe ad punctum liquescens assidue.[Beilstein 3 IV 1123.]
