Adipose minofu ndi mitundu yake

Adipose minofu - chapadera connective minofu kuti umagwira ntchito ngati yosungirako chachikulu mafuta mu mawonekedwe a triglycerides. Mu anthu, alipo m'njira ziwiri zosiyana: woyera ndi zofiirira. kuchuluka kwake ndi kufalitsa aliyense.

White adipose minofu ali ntchito zitatu: matenthedwe kutchinjiriza, makina khushoni, ndi, Chofunika kwambiri, gwero la mphamvu. Mwachidule chabe pansi pa khungu ndipo ndicho thupi insulator chifukwa amachititsa kutenthetsa katatu woipa kuposa nsalu ina. Mlingo wa kutchinjiriza zimadalira makulidwe a wosanjikiza izi. Mwachitsanzo, munthu ndi 2 mm wosanjikiza subcutaneous mafuta Mudzamva monga omasuka ngati n'kotheka pa 15 ° C, pamene ndi 1-mm - 16 ° C. Komanso adipose minofu azinga ziwalo ndi amaziteteza ku Phokoso.

Mwachitsanzo, ndi:

- mozungulira mtima;

- mu impso;

- kudzaza mozungulira malo;

- mkati zitsulo diso kumbuyo mwana wa m'diso la, etc.

Monga waukulu mphamvu sitolo, lili ake ndi mbadwa ya mowa mopitirira muyeso. Choncho, mphamvu akhoza kuwapeza pa gram mafuta (9 kcal) kuposa chakudya galamu (4 kcal) kapena mapuloteni (4 kcal). Komanso, ngati munthu anali ndi mphamvu owonjezera mu mawonekedwe a chakudya, kulemera kuwonjezeka amasokoneza sayenda wake.

Komabe, pali zoletsa zina pa ntchito mafuta ngati "mafuta". Choncho, minofu kuti uziyenda makamaka ndondomeko anaerobic (mwachitsanzo, erythrocytes) ayenera kulandira mphamvu kuchokera chakudya, ndipo iwo ayenera kukhala ndi malire chokwanira. Ndiponso mu zinthu zachilendo, ubongo zimadalira shuga ndipo sagwiritsa ntchito zidulo mafuta. Mu zinthu zachilendo, kagayidwe kachakudya, akhoza kugwiritsa ntchito matupi ketone (a chochokera kwa chosakwanira kagayidwe mafuta), ngati iwo alipo lalikulu zedi mokwanira.

Brown adipose minofu walandira dzina la mtundu chifukwa vascularization olemera ndi mitochondria kuli ankanyamula, zimene zimapezeka mu malo osiyanasiyana.

M'malo kutumikira monga gawo lapansi, ndi lipids kumasulidwa mphamvu mwachindunji mu kutentha. Limagwirira a mbadwo wake kugwirizana ndi kagayidwe wa mitochondria lapansi.

The amuzolengedwa ndondomeko ejection mphamvu monga kutentha adamulowetsa milandu kumene wonse thupi kutentha umayamba kuchepa. Poyankha hypothermia anthu secrete mahomoni kuti Zimachititsa kumasulidwa zidulo mafuta kuchokera triglycerides zimene pamapeto, yambitsa Thermogenin.

Anthu, zofiirira adipose minofu mapangidwe akuyamba pa masabata 20 a chitukuko yoopsa. Nthawi yobereka ndi pafupifupi 1% ya kulemera kwa thupi. wosanjikiza ake ili pafupi Mitsempha kupereka mpweya ubongo ndi ziwalo m'mimba ndi ozungulira kapamba, adrenals ndi impso. Chifukwa cha bulauni adipose minofu ziwalo mwana yofunika musati supercooled mu malo otsika kutentha.

Atabadwa mwana akuyamba kukhala woyera adipose minofu, zofiirira ndi amayamba kutha. An wamkulu alibe malo kudzikundikira ake, ngakhale kuti alipo (1% mwa kulemera kwa mafuta), koma mosintha wothira woyera.
