I-D-Proline iyi-asidi ephilayo ethathwa njenge-proteinogenic amino acid (esetshenziswa ku-biosynthesis yamaprotheni), nakuba ingenayo i-amino group -NH2 kodwa kunalokho i-amine yesibili.I-amine nitrogen yesibili isesimweni se-NH2+ ene-protonated ngaphansi kwezimo zebhayoloji, kuyilapho iqembu le-carboxy lisefomini −COO− elincishiwe."Uchungechunge oluseceleni" olusuka ku-α carbon luxhuma ku-nitrogen lwenza iluphu ye-pyrrolidine, luyihlukanise njenge-aliphatic amino acid.Ayibalulekile kubantu, okusho ukuthi umzimba ungawuhlanganisa usuka ku-amino acid L-glutamate engabalulekile.Ifakwe ikhodi yiwo wonke amakhodoni aqala nge-CC (CCU, CCC, CCA, neCCG).
I-D-Proline iyona kuphela i-proteinogenic amino acid eyi-amine yesibili, njengoba i-athomu yenitrogen ixhunywe kokubili ku-α-carbon kanye neketango lamakhabhoni amathathu akha iluphu.
I-Proline kanye nokuphuma kwayo kuvame ukusetshenziswa njengama-catalysts asymmetric ekuphenduleni kwe-proline organocatalysis.Ukwehliswa kwe-CBS kanye ne-proline catalysed aldol condensation yizibonelo ezivelele.Ekwenziweni kotshwala, amaprotheni anothe nge-proline ahlangana nama-polyphenols ukukhiqiza inkungu (turbidity).I-D-Proline iyi-osmoprotectant ngakho-ke isetshenziswa ezinhlelweni eziningi ze-biotechnological.Indawo yokukhula esetshenziswa kusiko lezicubu zezitshalo ingase yengezwe nge-proline.Lokhu kungakhuphula ukukhula, mhlawumbe ngoba kusiza isitshalo ukubekezelela ukucindezeleka kwesiko lezicubu.Ngendima ye-proline ekuphenduleni ukucindezeleka kwezitshalo, Umsebenzi we-Biological.
