Ama-Macromolecule Ezinto Eziphilayo: Izinto Ezibalulekile Zokuphila
Ama-macromolecule e-organic ayiqembu lama-molecule amakhulu aqukethe ikhabhoni njengengxenye eyinhloko yesakhiwo. Ayizici ezibalulekile zokuphila futhi adlala indima ebalulekile ezinqubweni ezahlukene zezinto eziphilayo. Kunezinhlobo eziningana ezinkulu zama-macromolecule e-organic, okuhlanganisa ama-carbohydrate, amaprotheni, amafutha, nama-nucleic acid. Ngayinye yalezi zisebenza ezicini ezahlukene zokuphila, kusukela ekugcinweni kwamandla kuya ekubhaleni ulwazi lwezakhi zofuzo.
Ama-carbohydrate
Ama-carbohydrate angumthombo oyinhloko wamandla wezinto eziphilayo. Aqukethe amayunithi e-monosaccharide (ushukela olula) angahlanganiswa ukuze akhe ama-disaccharide, ama-oligosaccharide, nama-polysaccharide. Izibonelo zama-monosaccharide zifaka i-glucose ne-fructose, kuyilapho i-sucrose (ushukela wetafula) iyisibonelo se-disaccharide. Ama-polysaccharide, njengesitashi, i-glycogen, ne-cellulose, ayindlela yokugcina amandla noma isakhiwo ezintweni eziphilayo.
Umsebenzi wama-carbohydrate
1. Umthombo Wamandla: I-glucose, i-monosaccharide, iyi-molecule eyinhloko ekuphefumuleni kwamaseli, inqubo yokwenza amandla ezingeni lamaseli.
2. Amandla Agciniwe: Isitashi ezitshalweni kanye ne-glycogen ezilwaneni kusebenza njengesitoreji samandla sesikhathi eside.
3. Isakhiwo: I-Cellulose, i-polysaccharide equkethe amaketanga amade e-glucose, inikeza amandla kanye nokuvikelwa ezindongeni zamaseli ezitshalo.
4. Ukuxhumana Kwamaseli: Ama-Glycoprotein nama-glycolipid, atholakala ebusweni bamaseli, ahilelekile ekuqaphelweni kwamaseli kanye nokuxhumana phakathi kwamaseli.
amaprotheni
Amaprotheni ayi-macromolecules aguquguqukayo kakhulu akhiwe ngama-amino acid angu-20 ahlukene. Angenza cishe noma yimuphi umsebenzi weseli ngenxa yezakhiwo zawo ezihlukahlukene ezinezilinganiso ezintathu. Amaprotheni ahilelekile ekuvuseleleni ukusabela kwamakhemikhali (ama-enzyme), ekuthuthweni kwama-molecule, ezisekelweni zezakhiwo, kanye neminye imisebenzi eminingi.
Umsebenzi weProtheyini
1. Ama-enzyme: Amaprotheni asheshisa ukusabela kwamakhemikhali emzimbeni. Isibonelo, i-catalase isheshisa ukuqhekeka kwe-hydrogen peroxide ibe ngamanzi nomoya-mpilo.
2. Isakhiwo: Amaprotheni anjenge-collagen ezicutshini ezixhumeneyo kanye ne-keratin ezinweleni nasezinzipho anikeza ukwesekwa ngokomzimba.
3. Ukuthutha: I-Hemoglobin, iphrotheni esemangqamuzaneni abomvu egazi, ithutha umoya-mpilo usuka emaphashini kuwo wonke umzimba.
4. Ukulawula Nokubonisa Izimpawu: Ama-hormone amaprotheni afana ne-insulin alawula ushukela wegazi, kanti ama-receptor e-membrane adlulisa izimpawu ezivela ngaphandle kweseli ziye ngaphakathi kwalo.
I-Lipid
Ama-lipid ayiqembu lama-macromolecule angancibiliki emanzini kodwa ancibilika ezinyibilikisini eziphilayo. Ayingxenye eyinhloko yama-membrane eseli futhi asebenza njengesitoreji samandla sesikhathi eside. Ama-lipid ajwayelekile kakhulu afaka amafutha, amafutha, ama-phospholipid, nama-sterols njenge-cholesterol.
Umsebenzi we-Lipids
1. Ukugcinwa Kwamandla: Amafutha agcina amandla aphindwe kabili kunama-carbohydrate ngegremu ngayinye.
2. Isakhiwo se-Membrane: Ama-Phospholipid akha ungqimba oluyi-bilayer oluyisisekelo sawo wonke ama-membrane eseli, egcina indawo yangaphakathi neyangaphandle yeseli.
3. Ukubonisa Nokulawula: Ama-hormone e-steroid, atholakala kuma-lipid, ahilelekile ekulawuleni izinqubo ezahlukene zomzimba, njenge-testosterone ne-estrogen ekulawuleni ukuzala.
4. Ukuvikela Nokuvikela: Amafutha aphinde ahlinzekele ukuvikela ukushisa ezilwaneni futhi avikele izitho zangaphakathi ekushayweni.
I-Nucleic Acid
Ama-Nucleic acid, okuhlanganisa i-DNA (deoxyribonucleic acid) kanye ne-RNA (ribonucleic acid), angama-macromolecule agcina futhi adlulise ulwazi lwezakhi zofuzo. Ayisisekelo sokuthola ifa lezimpawu zezinto eziphilayo kusukela kwesinye isizukulwane kuya kwesinye.
Imisebenzi yama-Nucleic Acids
1. Ukugcina Ulwazi Lwezakhi Zofuzo: I-DNA igcina ulwazi oludingekayo ukuze kwenziwe wonke amaprotheni emzimbeni.
2. Ukuvezwa Kwezakhi Zofuzo: I-RNA ikopisha ulwazi lwezakhi zofuzo oluvela ku-DNA bese iluhumusha lube amaprotheni ngezinqubo zokubhalwa nokuhumusha.
3. Ukulawulwa Kwezakhi Zofuzo: I-RNA ingasebenza futhi njengomlawuli womsebenzi wezakhi zofuzo, njenge-microRNA engalawula ukuvezwa kwezakhi zofuzo ezithile.
Ubudlelwano phakathi kwama-Macromolecule
Ama-macromolecule e-organic awasebenzi ngokwawo; avame ukusebenzisana futhi athintane ezinqubweni ezahlukene zezinto eziphilayo. Isibonelo:
– Ama-Glycoprotein nama-Glycolipid: Inhlanganisela yamaprotheni noma amafutha nama-carbohydrate emangqamuzaneni eseli idlala indima ekusebenzelaneni kweseli namaseli.
– I-DNA kanye neProtheyini: I-Chromatin, isakhiwo esiyinkimbinkimbi phakathi kwamaprotheni e-DNA kanye ne-histone, ilawula ukupakishwa kwe-DNA ku-nucleus yeseli.
– Amandla eMetabolism: Ama-lipid, ama-carbohydrate, namaprotheni konke kungaguqulwa kube amandla ngokusebenzisa izindlela ezixhumene ze-metabolic ezifana nomjikelezo we-Krebs.
Isiphetho
Ama-macromolecule ezinto eziphilayo ayizingxenye ezibalulekile zokuphila, okwenza kube nokwenzeka izinqubo ezahlukahlukene zezinto eziphilayo ezenza ukuba khona kwethu, kanye nokwazo zonke ezinye izinhlobo zokuphila. Ukuqonda ukuthi la ma-macromolecule asebenza futhi asebenzisana kanjani kusinika ukuqonda okungcono kwe-biology kanye nethuba lokuthuthuka kwezokwelapha, ubuchwepheshe be-bio, kanye nezolimo. Yiqiniso, ucwaningo luyaqhubeka nokwembula izimfihlakalo ezengeziwe ngala ma-macromolecule kanye nendima yawo empilweni.
