4-methyl L-aspartate (kapa 4-methylhydropyran aspartic acid) ke motsoako o nang le motsoako oa lik'hemik'hale C6H11NO4. Ke sehlahisoa sa methylation ho molek'hule ea L-aspartate.

Ho ea ka thepa ea eona, 4-methyl hydrogen L-aspartate ke ntho e tiileng, e qhibilihang ka metsing le ka har'a metsoako ea lintho tse phelang, tse kang alcohols le esters. E tsitsitse mocheso oa kamore 'me e ka futhumatsoa ka har'a mocheso o itseng ntle le ho bola.

4-methyl hydrogen L-aspartate e na le lits'ebetso tse itseng lefapheng la baeloji le bongaka. E ka sebelisoa e le karolo e ka hare ho motsoako oa lithethefatsi tse itseng, tse kang li-derivatives tsa amino acid tse sebelisoang ha ho etsoa li-blockers tse seng tsa ketofuran.

Mabapi le mokhoa oa ho itokisa, 4-methyl hydrogen L-aspartate e ka lokisoa ka methylation ea L-aspartic acid. Mokhoa o ikhethileng o kenyelletsa karabelo e sebelisang li-reagents tsa methylating joalo ka methanol le methyl iodide tlasa maemo a alkaline ho hlahisa 4-methyl hydrogen L-aspartate.

Motsoako ona o na le lintlha tse fokolang tsa polokeho. Joaloka motsoako oa lintho tse phelang, e ka 'na ea e-ba chefo' me ea halefisa, kahoo hoa hlokahala ho nka mehato e nepahetseng ea tšireletso ha u tšoara, joalo ka ho roala liatlana le likhalase. Ho phaella moo, ha ho sebelisoa kapa ho lahla motsoako, mekhoa e nepahetseng ea tšireletso e lokela ho lateloa.
