D-Proline ke asiti ea tlhaho e thathamisitsoeng e le protheine amino acid (e sebelisoang ho biosynthesis ea liprotheine), leha e se na sehlopha sa amino -NH2 empa ke amine ea bobeli.Naetrojene ea bobeli ea amine e ka sebopeho sa NH2+ se nang le protonated tlas'a maemo a tlhaho, ha sehlopha sa carboxy se le ka sebopeho sa −COO− se senyehileng."Ketane ea mahlakoreng" e tsoang ho α carbon e hokahana le naetrojene e etsa loop ea pyrrolidine, e e khethollang e le aliphatic amino acid.Ha e bohlokoa ho batho, ho bolelang hore 'mele o ka e kopanya ho tsoa ho amino acid e seng ea bohlokoa ea L-glutamate.E kentsoe likhoutung kaofela ho qala ka CC (CCU, CCC, CCA, le CCG).
D-Proline ke eona feela proteinogenic amino acid eo e leng amine ea bobeli, kaha athomo ea naetrojene e hoketsoe ka bobeli ho α-carbon le ketane ea likhabone tse tharo tse etsang loop.
Proline le lihlahisoa tsa eona hangata li sebelisoa e le li-catalysts tse sa tšoaneng ho proline organocatalysis reactions.Phokotso ea CBS le proline catalysed aldol condensation ke mehlala e hlahelletseng.Ha ho riteloa, liprotheine tse ruileng ka proline li kopana le polyphenols ho hlahisa moholi (turbidity).D-Proline ke osmoprotectant mme ka hona e sebelisoa lits'ebetsong tse ngata tsa biotechnological.Mokhoa oa ho hōla o sebelisoang moetlong oa linama tsa semela o ka tlatsetsoa ka proline.Sena se ka eketsa kholo, mohlomong hobane se thusa semela ho mamella khatello ea maikutlo ea lithane tsa setso.Bakeng sa karolo ea proline karabelong ea khatello ea limela, ts'ebetso ea baeloji.
