D-Proline bụ organic acid nke a na-ekewa dị ka proteinogenic amino acid (nke a na-eji na biosynthesis nke protein), n'agbanyeghị na ọ nweghị amino group -NH2 kama ọ bụ amine nke abụọ.Amine nitrogen nke abụọ dị n'ụdị NH2+ protonated n'okpuru ọnọdụ ndu, ebe otu carboxy nọ n'ụdị -COO- deprotonated.The "n'akụkụ yinye" si α carbon na-ejikọta na nitrogen na-eme a pyrrolidine loop, na-ekewa ya dị ka aliphatic amino acid.Ọ dịghị mkpa na ụmụ mmadụ, nke pụtara na ahụ nwere ike ịmepụta ya site na amino acid L-glutamate na-adịghị mkpa.Edebere ya na codons niile malite na CC (CCU, CCC, CCA, na CCG).
D-Proline bụ naanị proteinogenic amino acid nke bụ amine nke abụọ, dịka nitrogen atom na-ejikọta ma na α-carbon na n'agbụ nke carbon atọ nke na-eme akaghị.
A na-ejikarị proline na ihe ndị na-emepụta ya dị ka ihe na-akpata asymmetric na mmeghachi omume organocatalysis proline.Mbelata CBS na proline catalysed aldol condensation bụ ihe atụ pụtara ìhè.N'ime ime ihe, protein ndị bara ụba na proline jikọtara ya na polyphenols iji mepụta haze (turbidity).D-Proline bụ osmoprotectant ya mere eji ya n'ọtụtụ ngwa biotechnological.Enwere ike ịgbakwunye ihe na-eto eto nke a na-eji na omenala anụ ahụ osisi na proline.Nke a nwere ike ịbawanye uto, ikekwe n'ihi na ọ na-enyere osisi ahụ aka ịnagide nrụgide nke ọdịbendị anụ ahụ. Maka ọrụ proline na nzaghachi nrụgide nke osisi, ọrụ ndu.
