Inyama Adipose neentlobo zayo

inyama Adipose - yinto inyama ekhethekileyo nokuqina ukuba imisebenzi njengoko yokugcina siphambili amanqatha ngokohlobo triglycerides. Xa abantu, oko ekhona iintlobo ezimbini ezahlukeneyo: omhlophe nomdaka. kwexabiso layo kunye nokusasazwa ngamnye.

White adipose inyama inemisebenzi ezintathu: yokugquma thermal, ababetheki ngoomatshini, yaye, okona kubaluleke kakhulu, umthombo wamandla. Ngokomthetho oko phantsi nje kwesikhumba kwaye yokwambathisa umzimba omkhulu kuba liqhuba libe shushu ngokuphindwe kathathu na babenetyala ngaphezu kwabo amalaphu. Ubungakanani ekwambathiseni kuxhomekeke Ebubanzini kwale maleko. Ngokomzekelo, umntu ngomaleko-2 mm amanqatha ongama liya kuziva kahle kangangoko kunokwenzeka kwi-15 ° C, kanti nge-1 mm - 16 ° C. Ngaphezu koko, ijwabu adipose ezingqonge izibilini akhusele ukusuka intlokoma.

Umzekelo, ukuba:

- emhlabeni intliziyo;

- kule izintso;

- ukugcwalisa emhlabeni amalungu;

- ngaphakathi kwisokethi iliso emva lweliso lakho, njl

Njengoko ivenkile engundoqo amandla, ubonelela nalo stock yokusebenzisa kwemfuneko. Ngoko ke, amandla ezininzi zingafumaneka fat gram (9 kcal) kunokuba carbohydrate gram (4 kcal) okanye protein (4 kcal). Ukongeza, ukuba umntu wagcina amandla kwemfuneko ngohlobo carbohydrate, ukwanda ubunzima bekuya kuba buhlungu ukuhamba kwakhe.

Nangona kunjalo, kukho ezinye imiqathango ekusetyenzisweni kwamafutha njenge "amafutha". Ngenxa yoko, inyama zisebenzayo ngokuyintloko ngeenkqubo anaerobic (umz, erythrocytes) kufuneka afumane amandla carbohydrate, yaye kufuneka abe nomda eyaneleyo. Ngaphezu koko, phantsi kweemeko eziqhelekileyo, ingqondo ixhomekeke glucose awusebenzisi asidi okunamafutha. Kwiimeko ezingaqhelekanga, metabolic, unako ukusebenzisa imizimba ketone (eceleni of ayiphelelanga ngamanqatha metabolism), ukuba zikhona kukuninzi ngokwaneleyo.

Brown inyama adipose ifumene igama layo evela umbala ebangelwe vascularization izityebi mitochondria ezinabantu wapakisha, apho zifumaneka kwiindawo ngeendawo.

Kunokuba kube zeendawana, oko lipids ukukhululwa amandla ngqo ibe bubushushu. Indlela of isizukulwana yaso ezinxulumene nethe le mitochondria.

Le ezinto amandla Inkqubo ejection njengoko ubushushu lwenziwe kwiimeko apho ubushushu zomzimba uqala ukwehla. Ukuphendula emzimbeni abantu hormone ezivuselela nokukhululwa fatty evela triglycerides leyo, nayo, uvule Thermogenin.

Xa abantu, brown adipose izicwili Ukwakheka iqala emva kweeveki ezingama-20 Palsy. Ngethuba lokubeleka ngayo malunga ne-1% of ubunzima bomzimba. umaleko yayo ibekwe malunga imithambo yegazi Ukubonelela ioksijini ingqondo kunye namalungu esiswini kwaye ezingqonge injeke, adrenals kunye nezintso. Ngenxa inyama brown adipose ngamalungu lo yeentsana musa supercooled kwimeko-bume lobushushu eliphantsi.

Emva kokuzalwa komntwana uqala ukuphuhlisa adipose izihlunu emhlophe, brown kwaye iqalisa ukuba luphele. Umntu omdala akanayo nendawo wayenemfuyo yayo, nangona ekhoyo (malunga-1% ngokobunzima amanqatha), kodwa ixutywe ngokungakhethiyo olumhlophe.
