Ua kapa ʻia ʻo Vitamin K i ka vitamin coagulation.Mai kona inoa, hiki iā mākou ke ʻike i kāna hana physiological koʻikoʻi e hoʻoikaika i ka coagulation koko.I ka manawa like, pili pū ka huaora K i ka metabolism iwi.

ʻAʻole hoʻohana nui ʻia ka Vitamin K1 i nā mea hoʻohui meaʻai holoholona ma muli o kona kumukūʻai.Ua emi ka paʻa o ka menaquinone i ka meaʻai ma hope o ka extrusion, ka maloʻo a me ka uhi ʻana, no laila ua hoʻohana ʻia nā derivatives o VK3 (ma muli o ka hoʻihoʻi kiʻekiʻe): menadione sodium bisulfite, menadione sulfite Sodium bisulfate complex, menadione sulfonic acid dimethylpyrimidinone, a me menaquinone nicotinamide sulfite.

ʻO ka nele o ka Vitamin K i nā pōpoki

He ʻenemi maoli nā pōpoki no nā ʻiole, a ua hōʻike ʻia ua ʻai hewa nā pōpoki i ka lāʻau make ʻiole i loaʻa ka dicoumarin, e alakaʻi ana i ka hoʻolōʻihi ʻana i ke koko.He nui nā hōʻailona lapaʻau ʻē aʻe, e like me ka momona momona, ka maʻi ʻeha o ka ʻōpū, ka cholangitis, a me ka enteritis, hiki ke alakaʻi i ka malabsorption o nā lipids, a me ka lua ʻole o ka vitamin K.

Inā loaʻa iā ʻoe kahi pōpoki Devon Rex ma ke ʻano he pipi, he mea nui ia e hoʻomaopopo i ka hānau ʻana o ka pua i ka hemahema i nā kumu hoʻopili pili i ka vitamina K.

Pono ka Vitamin K no nā pōpoki

ʻAʻole hoʻonui ʻia ka nui o nā meaʻai popoki me ka huaora K a hilinaʻi i ka hana o nā meaʻai meaʻai holoholona a me ka synthesis i loko o ka ʻōpū liʻiliʻi.ʻAʻohe hōʻike no ka hoʻohui ʻana i ka vitamina K i ka meaʻai holoholona.Inā ʻaʻole he nui ka iʻa i loko o ka meaʻai pipi nui, ʻaʻole pono e hoʻohui.

Wahi a nā hoʻokolohua haole, ua hoʻāʻo ʻia nā ʻano meaʻai popoki ʻelua i hoʻopaʻa ʻia i ka salmon a me ka tuna, hiki ke hōʻike i nā hōʻailona lapaʻau o ka nele o ka huaora K i nā pōpoki.Ua make kekahi mau pōpoki wahine a me nā pōpoki i kēia mau meaʻai i ke kahe koko, a ua hoʻolōʻihi ʻia nā pōpoki e ola nei i ka wā hoʻopaʻa ʻana ma muli o ka nele o ka huaora K.

He 60 nā meaʻai popoki i loaʻa i ka iʻaμg.kg-1 o ka huaora K, he kuʻina i kūpono ʻole i nā pono o ka huaora K o nā pōpoki.Hiki ke hoʻokō ʻia nā pono o ka huaora K o ka pōpoki e ka hoʻohui ʻana i ka bacteria o ka ʻōpū me ka loaʻa ʻole o ka meaʻai pōpoki iʻa.ʻO ka ʻai ʻiʻo i loaʻa i ka iʻa e pono ai ka hoʻohui ʻana i nā hemahema i ka synthesis o nā huaora e nā microbes ʻōpū.

Pono i loko o ka ʻai popoki i waiwai i ka iʻa kekahi menaquinone, akā ʻaʻohe ʻikepili i loaʻa i ka nui o ka huaora K e hoʻohui.ʻO ka nui o ka meaʻai i ʻae ʻia he 1.0mg/kg (4kcal/g), hiki ke hoʻohana ʻia ma ke ʻano he ʻai kūpono.

Hypervitamin K i nā pōpoki

ʻAʻole i hōʻike ʻia ʻo Phylloquinone, ke ʻano kūlohelohe o ka vitamina K, i mea ʻawaʻawa i nā holoholona ma kekahi ala o ka hoʻokele (NRC, 1987).I nā holoholona ʻē aʻe ma mua o nā pōpoki, ʻoi aku ka liʻiliʻi o 1000 mau manawa i ka nui o ka meaʻai.

ʻO ka meaʻai pipi e pili ana i ka iʻa, ma waho aʻe o ka pono e hoʻolohe i nā hōʻailona o ka huaora K, pono hoʻi e hoʻolohe i nā hōʻailona o ka thiamine (vitamin B1)
