ʻO D-Proline kahi waika organik i helu ʻia ma ke ʻano he amino acid proteinogenic (hoʻohana ʻia i ka biosynthesis o nā protein), ʻoiai ʻaʻole i loko o ka pūʻulu amino -NH2 akā he amine lua.Aia ka lua amine nitrogen i loko o ke ʻano protonated NH2+ ma lalo o nā kūlana olaola, aʻo ka hui carboxy aia ma ke ʻano deprotonated −COO−.Hoʻopili ka "ʻaoʻao kaula" mai ke kalapona α i ka nitrogen e hana ana i kahi loop pyrrolidine, e hoʻokaʻawale ana iā ia he ʻakika amino aliphatic.ʻAʻole ia he mea nui i ke kanaka, ʻo ia hoʻi, hiki i ke kino ke synthesize ia mai ka amino acid L-glutamate.Hoʻopili ʻia ia e nā codons āpau e hoʻomaka me CC (CCU, CCC, CCA, a me CCG).
ʻO D-Proline wale nō ka proteinogenic amino acid he amine lua, no ka mea, ua hoʻopili ʻia ka atom nitrogen i ka α-carbon a i kahi kaulahao o ʻekolu kalapona i hana i ka loop.
Hoʻohana pinepine ʻia ʻo Proline a me kāna mau derivatives e like me nā catalysts asymmetric i nā hopena organocatalysis proline.ʻO ka hōʻemi CBS a me ka condensation aldol catalysed proline he mau laʻana koʻikoʻi.I ka hoʻoinu ʻana, hui pū nā protein waiwai i ka proline me nā polyphenols e hana i ka haze (turbidity).ʻO D-Proline kahi osmoprotectant a no laila hoʻohana ʻia i nā noi biotechnological he nui.Hiki ke hoʻonui ʻia ka mea ulu i hoʻohana ʻia i ka moʻomeheu mea kanu me ka proline.Hiki i kēia ke hoʻonui i ka ulu, ma muli paha o ke kōkua ʻana i ka mea kanu e ʻae i nā koʻikoʻi o ka moʻomeheu kiko.
