Ma Macromolecule Achilengedwe: Zinthu Zofunikira Pamoyo
Ma macromolecule achilengedwe ndi gulu la mamolekyu akuluakulu okhala ndi kaboni ngati gawo lalikulu la kapangidwe kake. Ndi zinthu zofunika kwambiri pa moyo ndipo amachita ntchito zofunika kwambiri m'njira zosiyanasiyana zamoyo. Pali mitundu ikuluikulu ingapo ya macromolecule achilengedwe, kuphatikizapo chakudya, mapuloteni, mafuta, ndi ma nucleic acid. Iliyonse mwa izi imagwira ntchito m'mbali zosiyanasiyana za moyo, kuyambira pakusunga mphamvu mpaka kulemba zambiri za majini.
Chakudya
Chakudya ndiye gwero lalikulu la mphamvu ya zamoyo. Zimakhala ndi mayunitsi a monosaccharide (shuga wosavuta) omwe amatha kuphatikizidwa kuti apange ma disaccharide, oligosaccharide, ndi ma polysaccharide. Zitsanzo za monosaccharide ndi shuga ndi fructose, pomwe sucrose (shuga wa patebulo) ndi chitsanzo cha disaccharide. Ma polysaccharide, monga starch, glycogen, ndi cellulose, ndi mtundu wa kusungira mphamvu kapena kapangidwe ka zamoyo.
Ntchito ya Chakudya
1. Gwero la Mphamvu: Glucose, monosaccharide, ndiye molekyulu yayikulu mu kupuma kwa maselo, njira yopangira mphamvu pamlingo wa maselo.
2. Kusunga Mphamvu: Wowuma mu zomera ndi glycogen mu nyama amagwira ntchito yosungira mphamvu kwa nthawi yayitali.
3. Kapangidwe: Cellulose, polysaccharide yokhala ndi unyolo wautali wa shuga, imapereka mphamvu ndi chitetezo ku makoma a maselo a zomera.
4. Kulankhulana kwa Maselo: Ma glycoprotein ndi ma glycolipid, omwe amapezeka pamwamba pa selo, amagwira ntchito yozindikira ndi kulumikizana kwa maselo.
mapuloteni
Mapuloteni ndi ma macromolecules osiyanasiyana opangidwa kuchokera ku ma amino acid 20 osiyanasiyana. Amatha kugwira ntchito iliyonse ya maselo chifukwa cha kapangidwe kawo kosiyanasiyana ka magawo atatu. Mapuloteni amagwira ntchito yoyambitsa machitidwe a mankhwala (ma enzymes), kunyamula mamolekyulu, kukonza kapangidwe, ndi ntchito zina zambiri.
Ntchito ya Mapuloteni
1. Ma Enzyme: Mapuloteni omwe amafulumizitsa zochita za mankhwala m'thupi. Mwachitsanzo, catalase imafulumizitsa kusweka kwa hydrogen peroxide kukhala madzi ndi mpweya.
2. Kapangidwe kake: Mapuloteni monga collagen mu minofu yolumikizirana ndi keratin mu tsitsi ndi misomali amapereka chithandizo chakuthupi.
3. Kuyenda: Hemoglobin, puloteni yomwe ili m'maselo ofiira a magazi, imanyamula mpweya kuchokera m'mapapo m'thupi lonse.
4. Kulamulira ndi Kupereka Zizindikiro: Mahomoni a mapuloteni monga insulin amawongolera shuga m'magazi, ndipo zolandirira za nembanemba zimatumiza zizindikiro kuchokera kunja kwa selo kupita mkati mwake.
Lipid
Ma lipid ndi gulu la ma macromolecules omwe sangasungunuke m'madzi koma amasungunuka mu zinthu zachilengedwe. Ndiwo zigawo zazikulu za nembanemba ya maselo ndipo amagwira ntchito yosungira mphamvu kwa nthawi yayitali. Mafuta odziwika bwino ndi mafuta, mafuta, phospholipids, ndi sterols monga cholesterol.
Ntchito ya Mafuta
1. Kusunga Mphamvu: Mafuta amasunga mphamvu zowirikiza kawiri kuposa chakudya pa gramu imodzi.
2. Kapangidwe ka Membrane: Ma phospholipid amapanga bilalayer yomwe ndi maziko a nembanemba zonse za selo, kusunga malo amkati ndi akunja a selo.
3. Kupereka Zizindikiro ndi Kulamulira: Mahomoni a steroid, omwe amachokera ku mafuta, amagwira ntchito yolamulira njira zosiyanasiyana za thupi, monga testosterone ndi estrogen pakuwongolera kubereka.
4. Kuteteza ndi Kuteteza: Mafuta amaperekanso chitetezo cha kutentha kwa nyama ndipo amateteza ziwalo zamkati kuti zisawonongeke.
Asidi ya Nyukiliya
Ma nucleic acid, kuphatikizapo DNA (deoxyribonucleic acid) ndi RNA (ribonucleic acid), ndi ma macromolecules omwe amasunga ndi kutumiza chidziwitso cha majini. Ndiwo maziko a cholowa cha makhalidwe a zamoyo kuchokera ku mibadwomibadwo kupita ku ina.
Ntchito za Nucleic Acids
1. Kusunga Chidziwitso cha Majini: DNA imasunga chidziwitso chofunikira popanga mapuloteni onse m'thupi.
2. Kufotokozera za majini: RNA imakopera chidziwitso cha majini kuchokera ku DNA ndikuchimasulira kukhala mapuloteni kudzera mu njira zolembera ndi kumasulira.
3. Kulamulira Majini: RNA imathanso kugwira ntchito ngati chowongolera zochita za majini, monga microRNA yomwe imatha kuwongolera momwe majini ena amagwirira ntchito.
Ubale pakati pa macromolecules
Ma macromolecule achilengedwe sagwira ntchito paokha; nthawi zambiri amalumikizana ndikukhudzana m'njira zosiyanasiyana zamoyo. Mwachitsanzo:
– Ma Glycoprotein ndi Ma Glycolipid: Kuphatikiza kwa mapuloteni kapena mafuta ndi chakudya m'maselo a maselo kumachita gawo pa kuyanjana kwa maselo.
– DNA ndi Mapuloteni: Chromatin, kapangidwe kovuta pakati pa mapuloteni a DNA ndi histone, imayang'anira kusungidwa kwa DNA mu nucleus ya selo.
– Mphamvu Kagayidwe: Mafuta, chakudya, ndi mapuloteni onse amatha kusinthidwa kukhala mphamvu kudzera m'njira zolumikizana za kagayidwe kachakudya monga kuzungulira kwa Krebs.
Mapeto
Ma macromolecule achilengedwe ndi zinthu zofunika kwambiri pa moyo, zomwe zimathandiza kuti zinthu zosiyanasiyana zamoyo zikhalepo zomwe zimapangitsa kuti tikhalepo, komanso za mitundu ina yonse ya zamoyo. Kumvetsetsa momwe macromolecule amenewa amagwirira ntchito komanso momwe zinthu zimagwirira ntchito kumatithandiza kumvetsetsa bwino za sayansi ya zamoyo komanso kuthekera kopita patsogolo mu zamankhwala, sayansi ya zamoyo, ndi ulimi. Inde, kafukufuku akupitilizabe kuvumbula zinsinsi zambiri zokhudza macromolecule amenewa ndi ntchito yawo pamoyo.
