D-Proline waa asiidh organic ah oo lagu sifeeyay sida amino acid proteinogenic (oo loo isticmaalo biosynthesis ee borotiinka), inkasta oo aysan ku jirin kooxda amino-NH2 laakiin waa amin labaad.Nitrojiinka aminiga sare waxa uu ku jiraa qaabka NH2+ protonated ee xaaladaha bayoolojiga, halka kooxda karboksigu ay ku jiraan qaabka -COO- oo la baabi'iyay."Silsilada dhinaca" ee ka timid carbon α waxay ku xirtaa nitrogen-ka sameynta loop pyrrolidine, oo u kala saarta sida amino acid aliphatic.Waa wax aan lagama maarmaan u ah bini'aadamka, taasoo la micno ah in jidhku ka soo saari karo amino acid-ka aan muhiimka ahayn ee L-glutamate.Waxaa lagu dhejiyay dhammaan koodnada laga bilaabo CC (CCU, CCC, CCA, iyo CCG).
D-Proline waa amino acid-ka kaliya ee borotiinnojiin ah kaas oo ah amin labaad, maadaama atamka nitrogen uu ku xidhan yahay α-carbon iyo silsilad saddex kaarboon ah oo samaysa wareeg.
Proline iyo waxyaalaheedii ayaa inta badan loo isticmaalaa kiciyayaal asymmetric ah falcelinta proline organocatalysis.Dhimista CBS iyo uumiga aldol ee proline katalysed ayaa ah tusaalayaal caan ah.Marka la samaynayo, borotiinada hodanka ku ah proline waxay ku daraan polyphenols si ay u soo saaraan caraf (turbidity).D-Proline waa osmoprotectant sidaas darteed waxaa loo isticmaalaa codsiyo badan oo bayotechnoolajiyada.Dhexdhexaadinta koritaanka ee loo isticmaalo dhaqanka unugyada dhirta waxaa laga yaabaa in lagu kabo proline.Tani waxay kordhin kartaa korriinka, laga yaabee sababtoo ah waxay ka caawisaa geedka inuu u dulqaado cadaadiska dhaqanka unugyada. Doorka proline ee jawaab-celinta walaaca ee dhirta, dhaqdhaqaaqa noolaha.
