Dipeptides

A mụọbeghị L-α-dipeptides (dipeptides) ọ fọrọ nke nta ka ọ bụrụ na enwere protein na amino acid.Emere nchọpụta mbụ na L-aspartyl-L-phenylalanine methylester (aspartame) na Ala-Gln (Lalanyl-L-glutamine) n'ihi na a na-eji ha na ngwaahịa azụmahịa na-ewu ewu.Na mgbakwunye na eziokwu a, ihe ọzọ kpatara na ọtụtụ dipeptides amụbeghị nke ọma bụ n'ihi na mmepụta dipeptide enweghị usoro mmepụta nke ọma, ọ bụ ezie na a kọwawo ọtụtụ usoro kemịkalụ na chemoenzymatic.

Ruo n'oge na-adịbeghị anya, e mepụtala ụzọ ọhụrụ maka njikọ dipeptide nke a na-emepụta dipeptides site na usoro fermentative.Ụfọdụ dipeptides nwere ikike physiological pụrụ iche, na-enye ha ohere ịme ngwa ngwa dipeptide n'akụkụ dị iche iche nke nyocha sayensị.L-a-dipeptides bụ nke nwere njikọ peptide na-enweghị mgbagwoju anya nke amino asịd abụọ, mana ha anaghị adị ngwa ngwa n'ihi mwepu nke usoro nrụpụta dị ọnụ ahịa.Otú ọ dị, Dipeptides nwere ọrụ na-adọrọ mmasị, na ozi sayensị gbara ya gburugburu na-abawanye.Nke a na-ahapụ ọtụtụ ndị na-eme nchọpụta na-ahụ maka ịmepụta usoro dị irè na nke dị ọnụ ala nke mmepụta dipeptide.Mgbe a na-amụ nke ọma n'ọhịa a, a na-atụ anya na anyị nwere ike ịmụtakwu banyere uru peptides bara uru n'ezie.

Dipeptides nwere ọrụ abụọ bụ isi, nke bụ:
1. Mwepụta nke amino acids
2. Dipeptide n'onwe ya

Dị ka ihe sitere na amino acids, dipeptides, yana amino acid ha nwere ihe dị iche iche nke physiochemical, mana ha na-enwekarị otu mmetụta physiological.Nke a bụ n'ihi na a na-emebi dipeptides n'ime amino acid dị iche iche dị n'ime ihe ndị dị ndụ, nke nwere mmetụta physicochemical dị iche iche.Dịka ọmụmaatụ, L-glutamine (Gln) bụ ihe na-ekpo ọkụ, ebe Ala-Gin (L-alanyl-L-glutamine) na-anabata okpomọkụ.

Ngwakọta kemịkalụ nke dipeptides na-eme dị ka ndị a:
1. A na-echekwa otu dipeptide niile na-arụ ọrụ (na-abụghị ndị na-etinye aka na ịmepụta njikọ peptide nke amino acids).
2. Amino acid echekwara nke otu carboxyl efu na-arụ ọrụ.
3. Amino acid na-arụ ọrụ na-emeghachi omume na amino acid ọzọ echekwara.
4. A na-ewepụ otu nchebe dị n'ime dipeptide.
