I-D-Proline i-asidi ye-organic ehlelwe njenge-proteinogenic amino acid (esetyenziswa kwi-biosynthesis yeeprotheni), nangona ingenayo iqela le-amino -NH2 kodwa kunokuba i-amine yesibini.I-amine nitrogen yesibini ikuhlobo lwe-NH2+ eneprotonated phantsi kweemeko zebhayoloji, ngelixa iqela le-carboxy likuhlobo lwe-deprotonated −COO−.I "chain chain" esuka kwi-α carbon idibanisa kwi-nitrogen eyenza i-pyrrolidine loop, ihlelwa njenge-aliphatic amino acid.Ayibalulekanga ebantwini, oku kuthetha ukuba umzimba unokuwenza kwi-amino acid engabalulekanga i-L-glutamate.Ifakwe iikhowudi kuzo zonke iikhowudo eziqala ngeCC (CCU, CCC, CCA, neCCG).
I-D-Proline yi-proteinogenic amino acid kuphela eyi-amine yesibini, njengoko i-athomu ye-nitrogen idityaniswe zombini kwi-α-carbon kunye nekhonkco leekhabhoni ezintathu ezenza i-loop.
I-Proline kunye ne-derivatives yayo ihlala isetyenziswa njenge-asymmetric catalysts kwi-proline organocatalysis reactions.Ukunciphisa i-CBS kunye neproline catalysed aldol condensation yimizekelo ebalaseleyo.Ekwenzeni utywala, iiprotheyini ezityebileyo kwiproline zidibanisa neepolyphenols ukuvelisa inkungu (turbidity).I-D-Proline yi-osmoprotectant kwaye ngoko isetyenziswa kwizicelo ezininzi ze-biotechnological.Indawo yokukhula esetyenziswa kwinkcubeko yezicubu zezityalo inokuncediswa ngeproline.Oku kunokunyusa ukukhula, mhlawumbi ngenxa yokuba inceda isityalo sinyamezele uxinzelelo lwenkcubeko ye-tissue.Kuba indima yeproline ekuphenduleni uxinzelelo lwezityalo, umsebenzi we-Biological.
