ʻO kēia nā mea waiwai no ko mākou kino. I ke kino o ke kanaka, kāohi lākou i ka permeability o nā membrane pūnaewele, a hoʻopili pū i nā hana metabolic. ʻO kēia mau mea kahi ʻāpana hoʻohui o nā lipid a he mea nui ia no ko mākou olakino a me ka nani.
Nā meaʻai waiwai Sterol:
Nā ʻano laulā o nā sterol
ʻO nā paukū kahi ʻāpana hoʻohui o nā mea momona a me nā momona holoholona. Pili lākou i ka hui o nā waiʻona polycyclic a loaʻa i loko o nā membrane o nā meaola āpau.
Loaʻa nā Sterol i ke kūlohelohe i nā mokuʻāina ʻelua: i ke ʻano o nā wai ʻona manuahi, a me ke ʻano o nā esters o nā waikawa momona kiʻekiʻe. I waho, he mea crystalline lākou, hiki ʻole ke hoʻohana ʻia i loko o ka wai.
Ua kapa ʻia nā Sterola i loko o nā meaola o nā holoholona a me nā kānaka i kapa ʻia he mau zosterol. ʻO ka mea kaulana loa o kēia ka kolesterol.
Uaʻike pū kekahi nā kānaka ʻepekema microbiologists i kekahi ʻano laha maʻamau - he mau sterol kēia o nā mea kanu haʻahaʻa a kiʻekiʻe hoʻi, i kapa ʻia ʻo nā phytosterols. ʻO B-sitosterol kēia, campesterol, stigmasterol, brassicasterol. Loaʻa lākou i nā mea kanu e like me ka ʻaila soybean a me ka aila rapeseed.
Eia hou, mycosterols (fungal sterols, ʻo kahi laʻana, ergosterol), a me nā sterol o nā microorganism, i loaʻa mau i ke ʻano. He mea maikaʻi loa ʻo Ergosterol no ke olakino kanaka. Ma lalo o ka mana o ke kukui ultraviolet, lilo ia i wikamina D. Hoʻohana ʻia nā sterols ʻoihana e hana i nā homone, a me nā huaora D pūʻulu.
Pono kēlā me kēia lā no nā sterola
'Saylelo nā Nutristists i kēlā me kēia lā o ka cholesterol e pono ʻole ma mua o 300 mg. Paipai ʻia nā sterol mea kanu e hoʻopau ʻia i kahi nui o 2-3 gram i kēlā me kēia lā.
No nā poʻe me ka puʻuwai a me nā pilikia vaskular, helu ʻia ka helu e like me ko lākou kūlana kino a me nā ʻōlelo a ke kauka.
Hoʻonui ka pono no nā sterols me:
- ke koko kiʻekiʻe o ke koko;
- nāwaliwali nāwaliwali;
- pre-stroke and pre-infarction state (hoʻohana ʻia nā phytosterols);
- lawa ʻole ka nui o nā wikamina A, E, K, D i loko o ke kino;
- me ka nele o ka ikaika;
- i ka wā o ka hāpai ʻana a me ka hānai ʻana i ka waiū;
- i ka hoʻoliʻiliʻi libido;
- inā pono, hoʻonui i ka ikehu wela;
- me ka hana kino paʻakikī;
- me ke koʻikoʻi koʻikoʻi kiʻekiʻe;
- me ka hōʻike o nā hōʻailona o ka maʻi rickets (hoʻohana ʻia ʻo ergosterol no ka mālama ʻana).
Ke emi nei ka pono no nā sterols:
I ka loaʻa ʻole o nā kumu i luna.
Digestibility o nā sterols
ʻO ke kaʻina hana o ka assimilation o nā lāʻau sterols mea ʻoi aku ka hana ma mua o nā holoholona. Pili kēia ʻike i ka ʻoiaʻiʻo o ka paʻa ʻana o ka kemika o nā phytosterols i ka liʻiliʻi o ke kūpaʻa ʻana i ka hana ʻana i ka wai ʻōpū. I kēia pili, hoʻohana ʻia lākou no ka hana mana kūloko.
Hiki i nā Zoosterols ke kū'ē i ka cleavage no ka manawa lōʻihi. A ʻo kēia hoʻi, kōkua i ke kanaka e hōʻemi iki i ka pōloli. Ua manaʻo ʻia ʻoi aku ka makemake o nā kāne i nā huahana i loaʻa nā sterols holoholona, a me nā wahine - e kanu i nā sterols.
Nā waiwai pono o nā sterol a me nā hopena ma ke kino
Wahi a nā noiʻi i mālama ʻia e nā mea mālama meaʻai Lūkini, ua ʻike ʻia a hōʻoia ʻia nā hopena maikaʻi o nā sterol i ke kino o ke kanaka.
Hoʻohana ʻia nā phytosterols e hoʻohaʻahaʻa i nā pae kolesterol, he mea nui ia i ka atherosclerosis. Hoʻoemi lākou i ka makaʻu o ka hahau a me ka puʻuwai puʻuwai. Loaʻa iā lākou kahi hana antioxidant i haʻi ʻia. Hoʻoikaika i ka ʻōnaehana pale maʻi.
Hoʻohui ʻia, ʻo nā sterols ka mea waiwai no nā wikamina A a me E i nā momona mea kanu, a me ka huaora D i nā holoholona. I ka lāʻau lapaʻau, hoʻohana ʻia nā sterol e hana i nā hormones steroid, a me synthesize i ka wikamina D a me nā lāʻau ʻē aʻe.
Ka launa pū me nā mea ʻē aʻe:
ʻO nā Sterols nā mea hoʻoheheʻe kūpono no ka carotene (provitamin A), a me nā huaora K, E a me D. Eia hou, hana pū nā sterol i kahi hana halihali i ke kino Hāpai lākou i nā protein i nā meaola a me nā mea āpau o ke kanaka.
Nā hōʻailona o ka nele o nā sterol i ke kino
- atherosclerosis (me ka hemahema o nā phytosterols);
- luhi;
- luhi luhi;
- hoʻololi i ke ʻano;
- hoʻemi i ka hana moekolohe;
- kūlana maikaʻi ʻole o nā kui;
- palupalu o ka lauoho;
- ke kaulike o ka hormonal;
- haʻahaʻa palekana;
- ʻelemakule ʻelemakule.
Nā hōʻailona o nā sterol i ke kino
- atherosclerosis (ʻoi aku ke kolesterol);
- hoʻonui i nā kūpili o ke koko;
- ka hoʻoulu ʻana i ka ulu ʻana o nā pōhaku a me nā pōhaku hepatic;
- nāwaliwali o nā mea osteochondral;
- hoʻonui ke koko;
- ʻeha ma ka puʻuwai;
- nā hoʻololi i ka hana o ke akepaʻa a me ka lepe.
Nā kumu e hoʻopili ana i ka nui o nā sterol i ke kino
ʻO ka mea nui e pili ana i ka ʻike o nā phytosterols i ke kino ʻo ia ka meaʻai. Hiki ke hoʻokumu ʻia nā zoosterols mai nā huahana o ke kumu carbohydrate a me nā momona, a komo pū i ko mākou kino me ka meaʻai. ʻO ka hanaʻole o ke kino ke alakaʻi i ka hōʻiliʻiliʻana o nā sterols i loko o ke kino, akā i ka manawa like e ho'ēmi i ko lākou absorption.
ʻO nā Sterola no ka nani a me ke olakino
Minamina, ʻo ka hapa nui o ka moekolohe maikaʻi, i ka ʻimi ʻana i ka leo i makemake ʻia, hōʻole e hoʻopau i nā momona - nā kumu o nā sterol. Ma ka ʻaoʻao hoʻokahi, he manawa maoli kēia e lilo ai ka paona. Akā hōʻoia ʻo ia iā ia wale nō inā kū ka nui o ke kaupaona a pale i ke kanaka mai ke alakaʻi ʻana i kahi nohona hana.
Inā ʻole, aia ka makaʻu o ka lilo i mea huhū, lauoho huluhulu, ʻili maloʻo a me nā kui kuʻi. Hoʻohui ʻia, alakaʻi ʻole ka nele o nā sterol i ka hōʻemi ʻana i ka ʻike maka a me nā pilikia hānau.
Hiki ke mālama ʻia nā hopena o ka papaʻai momona momona me ka lawe kaulike ʻana o nā sterol, ʻai i nā momona holoholona a me nā mea kanu.
