Adipose tishu uye mhando dzayo

Zvinyama zvinyama zvinoshandiswa zvakasiyana-siyana zvinoshandiswa sezvinonyanya kuchengetedzwa kwamafuta nenzira ye triglycerides. Muvanhu, iripo mumhando mbiri dzakasiyana-siyana: chena uye tsvuku. Nhamba yaro uye kugoverwa kune mumwe munhu.

Mishonga yakachena yakachena inoita mabasa matatu: kushambadzira kwemafuta, magetsi emagetsi uye, kunyanya kukosha, inopa simba. Chaizvoizvo, iri pasi peganda uye ndiyo inonyanya kushambadzira muviri wemuviri, nokuti inoita kuti kupisa katatu kuve kwakaipisisa kupfuura mamwe matukisi. Dhigirii rekusimbiswa kunobva pane kuwanda kweizvi. Semuenzaniso, munhu ane 2-mm-layer ye-subcutaneous fat achanzwa seanononoka sezvinobvira pa15 ° C, asi ane 1 mm-16 ° C. Mukuwedzera, maronda ane mafuta anopoteredza nhengo dzomukati uye anovapa kudzivirirwa kurwisana.

Somuenzaniso, iripo:

- yakakomba mwoyo;

- muitsvo;

Kuzadza zvakapoteredza joints;

- mukati mejinga reziso, seri kwebhokisi reziso, nezvimwewo.

Sekuchengetedza kukuru kwemasimba, inopa nhumbi dzayo nekuwedzerwa kushandiswa. Somugumisiro, simba rakawanda rinogona kuwanikwa kubva kune gramu yemafuta (9 kcal) kupfuura kubva pagiramu yemakrohydrates (4 kcal) kana protein (4 kcal). Mukuwedzera, kana munhu akachengetwa simba rakawandisa mumararidhahydrates, kuwedzera mukuwanda kunopesana nekufamba kwake.

Zvisinei, pane zvimwe zvipingamupinyi pakushandiswa kwamafuta se "mafuta". Nokudaro, mishonga inoshandiswa kunyanya kuburikidza nevanaerobic (semuenzaniso, erythrocytes) inofanira kuwana simba kubva kumahydrohydrates uye inofanira kuva nehuwandu hweiyo. Mukuwedzera, pasi pemamiriro ezvinhu akaenzana, uropi hunoenderana neglucose uye hahushandisi fatty acids. Mune mamiriro asingaoneki emagetsi, anokwanisa kushandisa miviri ye ketone (a--chibereko chese mafuta asingagadziri metabolism) kana aripo mune zvakawanda zvakakwana.

Iyo mavara ane mavara ane mavara ane mazita ayo nemhaka yemuvara unokonzerwa nevapfumi vascularization uye zvakasimba yakazara mitochondria, inogona kuwanikwa munzvimbo dzakasiyana-siyana.

Panzvimbo yekushanda se substrate, iyo lipids mukati mayo inosunungura simba zvakananga nenzira yekupisa. Iyo nzira yechizvarwa chayo inobatanidza ne metabolism mu mitochondria.

Nzira yehupenyu hwemhepo inosunungurwa nenzira yekupisa inogadziriswa mumatambudziko iwayo apo hutano hwemuviri hutanga kuderera. Mukupindura ku hypothermia mumuviri womunhu, mahomoni anosunungurwa anosimudzira kusunungurwa kwemafuta acids kubva ku-triglycerides, iyo inoshandisawo thermogenin.

Muvanhu, kuumbwa kwebhuruu adipose tissue kunotanga pavhiki ye20 yekuvandudza intrauterine. Pakuberekwa, inenge 1% yehutatu hwemuviri. Iyo yakavhara inenge yakapoteredza mishonga yeropa inopa oxygen kuuropi uye nhengo dzomuviri mudumbu, uye inopoteredza pancreas, adrenals neitsvo. Kutenda kune mavara e-brown adipose, nhengo dzinokosha dzechecheche dzinenge dzisingasvikiki mumhepo yakadzika-inotonhora.

Mushure mokuberekwa, mwana anotanga kuve nemafuta machena, uye maronda anotanga kupera. Munhu mukuru haana nzvimbo dzemasumbu ake, kunyange zvazvo aripo (anenge 1% yehuwandu hwemafuta), asi ane chisungo chakasanganiswa nemuchena.
