Mapuroteni ari mukudya kwebhiza

Mapuroteni ari mukudya kwebhiza

Mushure memvura, mapuroteni ndiwo akanyanya kuwanda mumuviri webhiza, kubva kuuropi kusvika kumahwanda. Mapuroteni anopfuura kungoita tsandanyama. Aya ma enzymes, masoja ekudzivirira chirwere, DNA/RNA, hemoglobin, cell receptors, cytokines, mahomoni akawanda, connective tissue. Hazvina maturo kutaura, protein (aka protein) chinhu chakakosha zvikuru chekudya.

Mamiriro eprotein molecule akaoma kunzwisisa zvokuti zvinoshamisa kuti anogayiwa sei zvachose. Bhora rimwe nerimwe rine ruvara pamufananidzo iketani yemamino acids. Maketani akabatanidzwa kune mumwe nemumwe nemamwe makemikari zvisungo, izvo zvinogadzira kutevedzana uye chimiro chekupedzisira molecule. Puroteni yega yega ine seti yayo yemaamino asidhi uye yakasarudzika kutevedzana kweaya amino asidhi uye chimiro chaanozomonyoroka.

Maprotein molecules anoenda kukutanga "processing" atova mudumbu - pasi pekuita kwegastric juice, molecule inosunungura, uye zvimwe zvisungo pakati peamino acid cheni zvinoputsika (iyo inonzi "denaturation" inoitika). Kupfuurirazve mudumbu diki, macheni anozobuda emaamino acids, pasi pesimba reprotease enzyme inobva pancreas, inoputsika kuita amino acids, mamorekuru ayo atove madiki zvekupfuura nepamadziro emukati uye kupinda mukati. ropa. Kana yangopinzwa, maamino acids anounganidzwa zvakare kuita mapuroteni anodiwa nebhiza. ----- Ndichaita diki dhigiri: Munguva pfupi yapfuura kune vamwe vanogadzira vanogadzira vanoti protein mune imwe nzira isina kugadziriswa munzira uye saka haina kuyananiswa uye inofanana nebasa rayo, kusiyana nemakwikwi, umo mapuroteni anodzorwa uye anorasikirwa nekuita kwavo kwehupenyu mukuita. kupisa kana kumwe kugadzirisa. Mashoko akadaro haasi chimwe chinhu kunze kwekutengesa kwekutengesa! Kutanga, kupinda mudumbu remukati, chero puroteni inobviswa pakarepo, kana zvisina kudaro puroteni yakakura haigone kupinzwa muropa kuburikidza nemadziro emukati. Kana protein yatove denatured, inokurumidza yakagayiwa, nekuti unogona kusvetuka danho rekutanga. Kana zviri zvebhayoloji, zvinoreva mabasa anoitwa neprotein chaiyo mumuviri. Nezve bhiza, basa rehupenyu hwemapuroteni emiti (somuenzaniso, photosynthesis) harina kunyanya kudiwa kwaari. Muviri pachawo unounganidza mapuroteni kubva kune ega amino acids neiyo biological chiitiko chinodiwa kune ichi chipenyu.

—————- Mapuroteni asina nguva yekugayiwa mudumbu diki anopinda mumashure emukati, uye ipapo, kunyangwe achigona kudyisa microflora yeko, anenge atove asingabatsiri kumuviri webhiza (kubva ipapo anogona chete. enderera mberi nekubuda). Manyoka anogona kukonzeresa.

Muviri unogara uchiputsa mapuroteni aripo uye unogadzira matsva. Muchiitiko ichi, mamwe amino acids anobudiswa kubva kune mamwe aripo, mamwe asingakoshi anobviswa kubva mumuviri, nokuti kukwanisa kuchengeta mapuroteni emangwana haapo mubhiza (uye chero imwe, zvichida) zvisikwa.

Uyezve, iyo amino acid haina kubviswa zvachose. Boka reamino rine nitrogen rakaparadzaniswa kubva pairi - rinobudiswa, rapfuura nenzira yakaoma yekushandura, nenzira ye urea ine urini. Iro boka recarboxyl rasara rinochengetwa uye rinogona kushandiswa kugadzira simba, kunyangwe iyi nzira yekuwana simba iri nyore uye inopedza simba.

Chinhu chimwe chetecho chinoitika nemamwe maamino acids anobva muchikafu chine mapuroteni. Kana vakakwanisa kugayiwa uye kunyudzwa muropa, asi muviri haudi izvozvi, nitrogen inoparadzaniswa uye inoburitswa muweti, uye iyo kabhoni yasara inopinda mumatura, kazhinji mafuta. Chidyiro chinonhuwirira chakasimba cheammonia, uye bhiza rinowedzera kunwa kwaro kwemvura (weti inofanira kugadzirwa kubva pane chimwe chinhu!)

Izvo zvataurwa zvinotisvitsa kumubvunzo wekuti kwete chete kuwanda, asiwo kunaka kweprotein. Hunhu hwakanakisa hweprotein ndehwekuti ese maamino acids ari muchiyero chakafanana umo muviri unoda iwo.

Pane matambudziko maviri pano. Kutanga: hazvisati zvanyatsozivikanwa kuti mari iyi chii, iyo inowedzera kuchinja zvichienderana nemamiriro ehupenyu. Naizvozvo, panguva ino, chiyero cheamino acids mumhasuru dzebhiza (uye mumarasi anoyamwisa - zvakare mumukaka) inotorwa seyakanaka, sezvo tsandanyama dzichiri kuwanda kweprotein. Parizvino, iyo yakazara kudiwa kwe lysine yakawongororwa zvakanyanya kana zvishoma, saka yakajairwa. Mukuwedzera, lysine inoonekwa seyo huru inodzikamisa amino acid. Izvi zvinoreva kuti kazhinji chikafu chine lysine shoma pane inodiwa zvichienzaniswa nemamwe amino acids. Izvi zvinoreva, kunyange kana huwandu hweprotein hwakakwana, muviri unozokwanisa kuushandisa chero bedzi uine lysine yakakwana. Kana iyo lysine yapera, amino acids asara haagone kushandiswa uye anoparara.

Threonine uye methionine zvakare inoonekwa seyakaganhurirwa. Ndosaka utatu uhwu huchiwanzo onekwa mumapfekero.

Nehuwandu, ingave crude protein kana digestible protein inogadziriswa. Zvisinei, iprotein isina kuchena iyo inonyanya kuratidzwa muzvokudya (zviri nyore kuverenga), saka zviri nyore kuvaka pamitemo yeprotein isina kuchena. Chokwadi ndechekuti crude protein inoverengerwa ne nitrogen content. Zviri nyore – vakaverenga nitrogen yese, ndokuzowanzwa neimwe coefficient ndokuwana crude protein. Nekudaro, iyi fomula haifungi nezvekuvapo kweasina mapuroteni mafomu e nitrogen, saka haina kunyatso kurongeka.

Zvakangodaro, pakugadzika zviyero zveprotein isina kuchena, kugaya kwayo kunotariswa (inofungidzirwa kuti iyi inenge 50%), saka unogona kushandisa zvizere zviyero izvi, uchirangarira, zvisinei, nezve kunaka kweprotein!

Kana iwe ukatarisisa kune chikafu chemukati chekudya (semuenzaniso pane chinyorwa pahomwe ye muesli), zvino ramba uchifunga kuti zvinoitika nenzira mbiri, uye haufaniri kuenzanisa zvisingaenzaniswi.

Kukakavadzana kwakawanda kunokonzerwa nekuwedzerwa kweprotein muzvokudya. Kusvikira munguva pfupi yapfuura, zvaidavirwa zvakafara kuti "protein poisoning" inokonzera laminitis. Iko zvino zvave zvichiratidzwa kuti iyi ingano, uye mapuroteni haana zvachose chekuita nelaminitis. Zvakangodaro, mapuroteni anopikisa haaregi uye anopokana kuti mapuroteni akawandisa anokanganisa itsvo (nekuti vanomanikidzwa kuburitsa nitrogen yakawandisa) uye chiropa (nekuti inoshandura chepfu ammonia kuita isiri-chepfu urea).

Nekudaro, veterinarians uye vekudya vanodzidza nezveprotein metabolism vanoti iyi ingano, uye kuti hapana nyaya dzakavimbika dzezvinetso zveitsvo munhoroondo yezvechiremba nekuda kwekuwanda kweprotein mukudya. Chimwe chinhu ndechekuti kana itsvo dzatove nedambudziko. Ipapo mapuroteni ari mukudya anofanirwa kuverengerwa zvakanyanya kuitira kuti arege kuvaremedza.

Handingapokane kuti kuwandisa kwakasimba kweprotein hakukuvadzi zvachose. Semuenzaniso, kune zvidzidzo zvinoratidza kuti kuwedzera kweprotein muzvokudya kunotungamirira kuwedzera muropa acidity panguva yekurovedza muviri. Uye kunyange zvazvo chidzidzo chacho chisingatauri chinhu pamusoro pemigumisiro yekuwedzera kweasidhi yeropa, chaizvoizvo izvi hazvina kunaka.

Panewo chinhu chakadai se "protein bumps". Nekudaro, kazhinji kazhinji mapundu aya haana chekuita nekudya. Kashoma, kusawirirana kune imwe puroteni kunogona kuitika, asi iri richava dambudziko rega rega.

Uye mukupedzisa, ndinoda kutaura pamusoro pekuongororwa kweropa. Muropa biochemistry kune chinhu chakadai se "Total protein". Nepo huwandu hweprotein hwekuverenga pasi pechinangwa hunogona (kunyangwe zvisingaite) kuratidza kusakwana kwekudya kweprotein yekudya, puroteni yakazara pamusoro peyakajairwa haina chekuita nehuwandu hweprotein mukudya! Chikonzero chinonyanyozivikanwa chekuwanda kweprotein yakazara kupera mvura! Kuwedzera kweprotein chaiyo mukudya kunogona kutongwa zvisina kunanga nehuwandu hweurea muropa, yakambobvisa, zvakare, kupera simba uye matambudziko etsvo!
