Yini i-monomer esetshenziselwa yona?

Amamomonderdlala indima ebaluleke kakhulu emikhakheni yamakhemikhali kanye ne-biology. Imvamisa amayunithi ayisisekelo enza ama-polymers (njengamaprotheni, ama-nucleic acid, nama-polysaccharides). Ngokukhethekile, ama-monomers axhumene ndawonye ngamabhondi athile amakhemikhali (njengama-peptide amabhondi, izibopho ze-phosphodiest, noma amabhondi e-glycosic) ukwakha amaketanga amade noma ama-polmermers amathathu.

Kwi-Biology, ama-monomers we-DNA ne-RNA angama-deoxyribononideotideotideotideideotideotideideotideotideotideideotideotideideotides kanye ne-ribonucleotides, ngokulandelana, ezixhunywe kwizakhiwo zamaketanga ngama-phosphodiester bond futhi ziphethe imininingwane yofuzo. Le khasiamamomonderAmaprotheni ama-amino acid, axhumene namaketanga e-polypeppide ngamabhondi e-peptopide, abese egoqwa futhi eguqulwa ukuze akhe ama-molecule e-protein ngemisebenzi ethile. Ama-monomers ama-polysaccharides angama-monosaccharides (anjenge-glucose, i-fructose, njll.), Axhumene nama-polysaccharides aphezulu we-polysaccharides anjenge-glycosidic bond, adlala indima ebalulekile ekugcinweni kwamandla.

Ngaphezu kwalokho, ama-monomers nawo asetshenziswa njengezinto zokwakha eziluhlaza noma eziphakathi embonini yamakhemikhali ukuhlanganisa izinto ezahlukahlukene ze-polymer, njengamapulasitiki, irabha, nemicu. Lezi zinto ze-polymer zisetshenziswa kabanzi empilweni yansuku zonke, ukukhiqizwa kwezimboni, kanye nentuthuko yesayensi nezobuchwepheshe.

Ngakho-ke,amamomonderAkuzona nje kuphela izinto eziyisisekelo ezakha izidalwa eziphilayo, kodwa futhi nezinto ezibalulekile ezingafani ezibaluleke kakhulu embonini yamakhemikhali yanamuhla.
