Protein ndicho chinokosha, ndiro chikamu plasma

Kukosha kweropa hazvigoni dzakanaka. mvura iyi zvakazara asangana chinokosha nadzo uye munyama, uye outputs matongo zvibereko muviri. Akafanirwa nechimwe ropa sero mumuviri anokwanisa zvizere dziripo.

Ropa rinoumbwa kupfuura hafu plasma. Plasma - imvura ine kuturika masero eropa - vanoumba anenge gumi muzana plasma. The Kuronga plasma zvikuru siyana - kuti amino acids uye peptides, bilirubin, creatine, uye dzimwe inclusions zhinji. Uyewo, Kuronga plasma ine mapuroteni - chimwe chezvinhu zvinokosha okunze.

Zvichienderana mamiriro avo, mapuroteni vakakamurwa muzvikwata - ndiko sealbumin, fibrinogen, globulins uye prothrombin. Vose vari chikamu plasma, apo kuita mabasa akasiyana-siyana. Plasma ropa mabasa ayo akawanda chaizvo, Zvinokurudzirwa vozoriwedzerwa kana wokuvhiya. Kunyanya yeplasma kunogona kubatsira munhu anoda kuwedzerwa.

Kupfuura vazhinji pakati zvose puroteni sealbumin. Vane nyore chaizvo (duku samolecular gobvu ose okunze), saka zviri nyore kutakura nokubatanidza nezvimwe zvinhu. Sealbumin ari chiropa. Muchikwata chechipiri pakukura mapuroteni - globulins, izvo vanoitwa zvinoberekwa chiropa. Ndoda mu yeplasma fibrinogen yakawanikwa - ndiko muzana chete anenge mana, asi zvisinei zvikuru kuti anodzivirira pezvakaitwa zhinji. Uye vakasvimha ropa rine prothrombin.

The mapuroteni dziri plasma, mabasa akasiyana mabasa. Nokuda kwavari ari kuparadzirwa mvura pakati munyama nemidziyo ropa, pane chinoramba kuti nguva dzose nemvura svikiro, masero zvinopa zvinovaka muviri uye "vakachenesa" kubva metabolic zvigadzirwa, tsvina uye kwete kuhupenyu nhengo. Mukuwedzera, mapuroteni zviri kuitika munyika makachengeteka ishande.

Sealbumin kuramba ari osmotic kumanikidzwa ropa. Izvi zvinoreva kuti havana anokonzera kwakakodzera BP Urume panguva imwe neimwe pfungwa muviri. Kana chikamu ropa sealbumin anowira, zvinogona kutungamirira kubviswa nemvura uye paumbwe edema (muenzaniso achideredza padanho sealbumin wakajeka - yechipiri yezana pamuviri preeclampsia). Chimwe basa rinokosha sealbumin - chokufambisa-siyana zvinhu. Albumins Kutamiswa nepandinogona zvinovaka muviri uye muchetura kuti neutralized nomuviri pedyo chiropa.

Globulins zvikuru mhosva kutapata muviri, agglutination (agglutination Kukwanisa erythrocytes kuti, uye nokudaro vakatsunga boka ropa).

Prothrombin akabatana fibrinogen anotipa chiyero rimwe viscosity ropa, riri kunyanya kukosha, nekuti zvepamusoro mwero wokufa kwevanhu munyika post-Soviet imhaka zvemwoyo. The plasma chinobata zvikuru mano midziyo ropa uye mwoyo kusvika Zvakanyanya Kunaka Panguva Yepamuviri zvifambiso ropa rose muviri. Kureva prothrombin uye kuchinja viscosity, uye nokudaro kunokanganisa mano midziyo nyore kutakura ropa nomuviri.

Fibrinogen - chinoshingaira ubatanidzwe pakugwamba kwacho. Zviri kuburikidza paumbwe fibrinogen pamusoro fibrin tambo, izvo zvinoumba clot - munhu clot. Kana anovhura, ropa mugumisiro fibrinogen kunobatsira kumisa ropa uye thrombus inotungamirwa uye goko (apo vanga pamusoro pemvura mugomba). Iri ropa pakugwamba kugona kuponesa muviri kubva chinokosha kurasikirwa neropa. Zvisinei, vamwe vanhu vanotambura vakadaro nechirwere chokuzvarwa nacho - nekusagona rimwe ropa. Kana X chromosome kutakura kukundikana mashoko, izvozvo zvingaita kuti hapana nokurasikirwa fibrin tambo, uye, naizvozvo, nekusagona clot inotungamirwa. kuremara Uyu mumwe mufananidzo unokosha sei mashandiro fibrinogen, sezvo risingagwambi vari kugara vachitya rufu neropa kurasikirwa kuchangotanga kukuvara.

The Zvinoumba plasma iri kusiyane, asi kuti mapuroteni vatambe inokosha basa. Nokuti murume zvakakosha kugara bvunzo kuti huwandu mapuroteni zvinoriumba uye, kana zvakakodzera, tora matanho kumisa homeostasis muropa zvakatipoteredza.
