Ko te D-Proline he waikawa waro kua tohua hei waikawa amino proteinogenic (e whakamahia ana i roto i te koiora o nga pūmua), ahakoa kaore i roto te roopu amino -NH2 engari he amine tuarua.Ko te hauota amine tuarua kei roto i te ahua NH2+ protonated i raro i nga tikanga koiora, ko te roopu carboxy kei roto i te ahua −COO− deprotonated.Ko te "mekameka taha" mai i te waro α e hono ana ki te hauota ka hanga i te porowhita pyrrolidine, ka whakarōpūtia hei waikawa amino aliphatic.Kare he mea nui i roto i te tangata, ko te tikanga ka taea e te tinana te whakahiato mai i te waikawa amino L-glutamate.Kei te whakawaeheretia e nga codons katoa timata ki te CC (CCU, CCC, CCA, me CCG).
Ko te D-Proline anake te waikawa amino proteinogenic he amine tuarua, i te mea ka piri te ngota hauota ki te waro-a-a me te mekameka o nga waro e toru e hanga ana hei koropiko.
He maha nga wa ka whakamahia te Proline me ona hua hei whakakōkī hangarite i roto i ngā tauhohenga proline organocatalysis.Ko te whakahekenga o te CBS me te condensation aldol kua whakapoapoa i te proline he tauira rongonui.I roto i te mahi pia, ka hono nga pūmua nui ki te proline ki te polyphenols ki te whakaputa kohu (pokarekare).Ko te D-Proline he osmoprotectant na reira ka whakamahia i roto i te maha o nga tono hangarau koiora.Ko te tikanga tipu e whakamahia ana i roto i te ahurea kiko tipu ka taapirihia ki te proline.Ka piki ake te tipu, tera pea ka awhina i te tipu ki te aro ki nga taumahatanga o te ahurea kiko.
