Kazhinji hunhu hwe sterols
Sterols chikamu chakakosha chemiriwo nemafuta emhuka. Ivo ndeveboka re polycyclic alcohol uye vanowanikwa mune membranes yezvose zvipenyu.
Sterols inowanikwa mune zvakasikwa mumatunhu maviri: muchimiro chemahara madoro, uye zvakare muchimiro cheesters emhando yepamusoro yemafuta acids. Nekunze, iwo chinhu chekristalline, isingasviki mumvura.
Sterols anowanikwa mune zvipenyu zvemhuka nevanhu anonzi zoosterols. Iyo inonyanya kuzivikanwa yeiyi cholesterol.
Masayendisiti ma microbiologist akaonawo imwe mhando yakajairika - aya ma sterol epasi uye akakwirira emiti, anonzi phytosterols. Aya ndiwo B-sitosterol, campesterol, stigmasterol, brassicasterol. Izvo zvinotorwa kubva kumidziyo yezvirimwa senge mafuta e soya uye rapeseed mafuta.
Mukuwedzera, mycosterols (fungal sterols, semuenzaniso, ergosterol), pamwe ne sterol ye microorganisms, achiri kuwanikwa mune zvakasikwa. Ergosterol inobatsira zvakanyanya kune hutano hwevanhu. Pasi pesimba re ultraviolet mwenje, inoshanduka kuita vhitamini D. Maindasitiri sterols anoshandiswa kugadzira mahormone, pamwe nevhithamini yeboka D.
Zuva nezuva kudiwa kwema sterols
Nutritionists vanoti muyero wezuva nezuva wecholesterol haufanire kudarika 300 mg. Zvirimwa sterols zvinokurudzirwa kudyiwa muhuwandu hwemagiramu maviri nemaviri pazuva.
Kune vanhu vane moyo uye matambudziko evascular, iyo mwero unoverengwa zvinoenderana nemamiriro avo epanyama uye nezano rachiremba.
Iko kudiwa kwe sterols kunowedzera ne:
- yakakwira ropa cholesterol;
- kusasimba kwekudzivirira muviri;
- pre-stroke uye pre-infarction nyika (phytosterols anoshandiswa);

Inobatsira zvimiro zve sterols uye zvazvinoita pamuviri
Zvinoenderana nezvidzidzo zvakaitwa neveRussia vezvehutano, izvo zvakanaka zvinokonzerwa nema sterol pamuviri wemunhu zvakaonekwa uye zvaratidzwa.
Phytosterols anoshandiswa kudzikisa ropa remafuta akawandisa, ayo anonyanya kukosha atherosclerosis. Dzinoderedza njodzi yekurohwa nechirwere chemwoyo. Ivo vane chakaziviswa antioxidant chiitiko. Inosimbisa immune system.

- atherosclerosis (nekushayikwa kwephytosterol);
- kuneta;
- kuneta kuneta;
- kuchinja kwemanzwiro;
- kuderera kwekuita zvepabonde;

Zvinhu zvinokanganisa huwandu hwemasterol mumuviri
Chinhu chikuru chinokanganisa zviri mukati me phytosterols mumuviri chikafu. Zoosterol inogona kuumbwa kubva kune zvigadzirwa zvemakabhohaidhiretsi mavambo uye mafuta, uye zvakare kupinda mumuviri wedu pamwe nechikafu. Kusashanda kwemuviri kunotungamirira kuunganidzwa kwesterols mumuviri, asi panguva imwe chete kunoderedza kutora kwavo.
Sterols yerunako uye hutano

Zvikasadaro, kune mukana wekushatirwa, bvudzi rakashama, ganda rakaoma uye brittle zvipikiri. Uye zvakare, kushomeka kwema sterol kunotungamira kudzikira kwekuona kwekuona uye matambudziko ekubereka.
Mhedzisiro yekudya kwakaderera-mafuta inogona kugadziriswa chete neyakaenzana kudya kwe sterols, kudya zvese mhuka nemafuta emiriwo.
