O le D-Proline o se vailaʻau faʻalaʻau faʻavasegaina o se amino acid proteinogenic (faʻaaogaina i le biosynthesis o polotini), e ui lava e le o iai le vaega amino -NH2 ae o se amine lona lua.O le amine nitrogen lona lua o loʻo i totonu o le NH2+ faʻapipiʻiina i lalo o tulaga olaola, ae o le vaega carboxy o loʻo i le deprotonated −COO− fomu.O le "filifili itu" mai le α carbon e fesoʻotaʻi i le nitrogen e fai ai se matasele pyrrolidine, faʻavasegaina o se amino acid aliphatic.E le taua i tagata, o lona uiga e mafai e le tino ona faʻapipiʻiina mai le amino acid L-glutamate e le taua.E fa'ailoga e codons uma e amata ile CC (CCU, CCC, CCA, ma CCG).
O le D-Proline e na'o le proteinogenic amino acid o se amine lona lua, ona o le nitrogen atom e fa'apipi'i uma i le α-carbon ma i se filifili o kaponi e tolu e fai ai se matasele.
O le Proline ma ona mea e maua mai e masani ona faʻaaogaina e pei o faʻamaʻi asymmetric i faʻasologa o le organocatalysis proline.O le fa'aitiitiga o le CBS ma le fa'aputuga o aldol fa'atosina o fa'ata'ita'iga iloga.I le fa'ainu, o polotini mauoa i le proline e tu'u fa'atasi ma polyphenols e maua ai le puao (gau).D-Proline o se osmoprotectant ma o lea e faʻaaogaina i le tele o faʻaoga faʻatekonolosi.E mafai ona fa'aopoopoina i le proline le ala o le tuputupu a'e o lo'o fa'aaogaina ile aganu'u a le tino.E mafai ona fa'atuputeleina le tuputupu a'e, masalo ona e fesoasoani i le la'au e fa'apalepale i fa'alavelave o le aganu'u a le tino.
