Thaum pib ntawm lub xyoo pua 20th, EmilFischer, tus yeej ntawm Nobel nqi zog nyob rau hauv Chemistry nyob rau hauv 1901, artificially synthesized dipeptide ntawm glycine thawj zaug, qhia tias tus qauv tseeb ntawm peptide yog tsim los ntawm amide pob txha.Tom qab ib xyoos, nws tau hais lo lus”peptide”, uas pib tshawb fawb txog peptide.

Amino acids ib zaug tau suav tias yog qhov tsawg tshaj plaws ntawm lub cev's nqus cov khoom noj protein, thaum peptides tsuas yog lees paub tias yog qhov thib ob decomposition ntawm cov protein.Nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab cov khoom noj khoom haus, cov kws tshawb fawb tau tshawb pom tias tom qab cov protein tau zom thiab decomposed, feem ntau, cov peptides me me uas muaj li ntawm 2 mus rau 3 amino acids tau ncaj qha absorbed los ntawm tib neeg cov hnyuv, thiab kev nqus tau zoo dua li ntawd. ntawm ib qho amino acids.Tib neeg maj mam lees paub tias me me peptide yog ib qho tseem ceeb tshaj plaws hauv lub neej, thiab nws txoj haujlwm tau koom nrog txhua qhov ntawm lub cev.

Peptide yog polymer ntawm amino acid, thiab ib hom kev sib xyaw ntawm cov amino acid thiab cov protein, thiab muaj ob lossis ntau tshaj ob cov amino acids txuas rau ib leeg los ntawm cov saw peptide.Yog li ntawd, nyob rau hauv ib lub sij hawm, peb yuav xav txog peptide yog tsis tiav decomposition khoom ntawm cov protein.

Peptides yog tsim los ntawm cov amino acids nyob rau hauv ib qho kev txiav txim txuas los ntawm peptide saw.

Raws li qhov lees txais nomenclature, nws muab faib ua oligopeptides, polypeptide thiab protein.

Oligopeptide yog tsim los ntawm 2-9 amino acids.

Polypeptide yog tsim los ntawm 10-50 amino acids.

Protein yog peptide derivative uas muaj ntau tshaj 50 amino acids.

Nws yog ib qho kev pom tias thaum cov protein nkag mus rau hauv lub cev, thiab nyob rau hauv qhov kev txiav txim ntawm ib tug series ntawm digestive enzymes nyob rau hauv lub digestive ib ntsuj av yuav zom mus rau hauv polypeptide, oligopeptide, thiab nws thiaj li decomposed mus rau hauv dawb amino acids, thiab kev nqus rau lub cev rau cov protein tsuas yog ua tau. ua nyob rau hauv daim ntawv ntawm dawb amino acids.

Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb lom neeg niaj hnub thiab khoom noj khoom haus, cov kws tshawb fawb tau pom tias oligopeptide tuaj yeem nqus tau los ntawm txoj hnyuv, thiab maj mam txais los ntawm tib neeg raws li oligopeptide hom I thiab hom II cov neeg nqa khoom tau ua tiav cloned.

Cov kev tshawb fawb tshawb fawb tau pom tias oligopeptide muaj cov txheej txheem nqus dej tshwj xeeb:

1. Kev nqus ncaj qha yam tsis muaj kev zom zaub mov.Nws muaj cov yeeb yaj kiab tiv thaiv ntawm nws qhov chaw, uas yuav tsis raug rau enzymatic hydrolysis los ntawm cov enzymes hauv tib neeg txoj hnyuv, thiab ncaj qha nkag mus rau hauv cov hnyuv hauv daim ntawv ua tiav thiab nqus los ntawm cov hnyuv.

2. Kev nqus sai.Tsis muaj pov tseg los yog excrement, thiab kho cov hlwb puas.

3. Raws li tus choj ntawm cov neeg nqa khoom.Hloov txhua yam ntawm cov as-ham rau cov hlwb, cov kabmob thiab cov koom haum hauv lub cev.

Nws yog dav siv nyob rau hauv ntau lub teb xws li kev kho mob, khoom noj khoom haus thiab tshuaj pleev ib ce nrog nws yooj yim haum, nplua nuj as-ham thiab ntau yam physiological nyhuv, uas yog ib tug tshiab kub taw tes nyob rau hauv high-tech teb.Me me molecule peptide tau lees paub los ntawm National Doping Control Analysis Organization ua cov khoom muaj kev nyab xeeb rau cov neeg ncaws pob siv, thiab Cov Neeg Liberation Army Yimth Ib Lub Tuam Txhab Muaj Peev Xwm tau noj cov tshuaj me me peptides.Me me molecule peptides tau hloov lub zog tuav siv los ntawm cov neeg ncaws pob yav dhau los.Tom qab kev sib tw kev sib tw siab, haus ib khob me me molecule peptides yog qhov zoo dua rau kev ua kom lub cev muaj zog thiab tswj kev noj qab haus huv dua li lub zog tuav.Tshwj xeeb tshaj yog rau cov nqaij ntshiv thiab pob txha puas tsuaj, kev kho ntawm me me molecule peptides yog irreplaceable.
