D-Proline ndi organic acid yomwe imatchedwa proteinogenic amino acid (yomwe imagwiritsidwa ntchito mu biosynthesis ya mapuloteni), ngakhale ilibe gulu la amino -NH2 koma ndi amine yachiwiri.Nayitrojeni wachiwiri wa amine ali mu mawonekedwe a protonated NH2+ pansi pamikhalidwe yachilengedwe, pomwe gulu la carboxy liri mu mawonekedwe -COO− odetsedwa."Unyolo wam'mbali" wochokera ku α carbon umalumikizana ndi nayitrogeni kupanga loop ya pyrrolidine, ndikuyiyika ngati aliphatic amino acid.Ndizosafunikira mwa anthu, kutanthauza kuti thupi limatha kupanga kuchokera ku amino acid L-glutamate osafunikira.Imasungidwa ndi ma codon onse kuyambira ndi CC (CCU, CCC, CCA, ndi CCG).
D-Proline ndiye proteinogenic amino acid yokhayo yomwe ndi amine yachiwiri, monga atomu ya nayitrojeni imamangiriridwa ku α-carbon ndi unyolo wa ma carbons atatu omwe amapanga loop.
Proline ndi zotumphukira zake nthawi zambiri amagwiritsidwa ntchito ngati chothandizira cha asymmetric muzochita za proline organocatalysis.Kuchepetsa kwa CBS ndi proline catalysed aldol condensation ndi zitsanzo zodziwika bwino.Popanga moŵa, mapuloteni olemera mu proline amaphatikizana ndi ma polyphenols kupanga chifunga (turbidity).D-Proline ndi osmoprotectant choncho amagwiritsidwa ntchito mu biotechnological ntchito zambiri.Sing'anga yakukulira yomwe imagwiritsidwa ntchito mu chikhalidwe cha minofu ya zomera ikhoza kuwonjezeredwa ndi proline.Izi zikhoza kuonjezera kukula, mwina chifukwa zimathandiza chomera kulekerera kupsyinjika kwa minofu chikhalidwe.Pakuti proline ntchito mu kupsinjika maganizo kwa zomera, Biological ntchito.
