Albumin yog Protein tseem ceeb tshaj plaws hauv tib neeg plasma

Albumin (albumin, tseem hu ua albumin) yog cov protein tseem ceeb tshaj plaws hauv tib neeg cov ntshav, uas tswj lub cev noj zaub mov thiab osmotic siab. Cov concentration nce mus txog 38 ~ 48g / L, suav txog li 50 feem pua ​​​​ntawm tag nrho cov ntshav plasma protein. Lub siab synthesizes txog 12g-20g albumin txhua hnub. Cov laus albumin yog ib txoj hlua polypeptide uas muaj 585 amino acid residues, thiab cov duab molecular yog oval. [1] Qhov concentration ntawm globulin yog 15 ~ 30g / L. Albumin / globulin (a / g) muaj qhov tseem ceeb hauv kev kho mob. Tus nqi ib txwm muaj ntawm a / G yog 1.5 ~ 2.5: 1. Qhov nce ntawm a / g tuaj yeem yog qhov nce ntawm albumin los ntawm kev noj zaub mov tsis txaus lossis tsis muaj immunoglobulin (antibody). Qhov txo qis ntawm a / g tuaj yeem yog vim qhov txo qis ntawm albumin: ① txo qis ntawm cov khoom siv hluav taws xob, ② nce ntxiv ntawm cov hlab ntsha exudation, raum sclerosis, protein exudative gastrointestinal o, siab cirrhosis, kub hnyiab, malignant qog, thiab lwm yam; Los yog vim qhov nce ntawm globulin: (1) nce cov tshuaj tiv thaiv kab mob los ntawm cov kab mob sib kis, thiab cov protein ntau txawv txav los ntawm cov pob txha pob txha. Kev txo qis ntawm cov ntshav albumin thiab a / G muaj qhov tseem ceeb hauv kev kho mob hauv kev xav txog qib ntawm daim siab ua haujlwm hauv daim siab mob siab.
