Mapuroteni usage

Mapuroteni anonzi nitrogenous macromolecular Organic zvinhu. Dzinovakwa kubva amino acids. Mapuroteni kuita zvinhu mabasa marongerwo uye anokosha pane zvinenge, sezvo chavainyanya zvinoriumba uye zvakakodzera. Nokuda izvi Organic yeimwe iri muviri, simba kutendeuka.

Nokuda pfupi guru ukuru mamorekuru, kunzwisisa kwakaita mamiriro, uyewo kushaya ruzivo pamusoro STRUCTURAL Zvinoumba akawanda zvinhu haangasimbiswi ndaisagona rakabatana kupatsanura kwemapurotini. The kuparadzana ino kunonyanya zvemasanga. Kana kuvaka yakanga yakavakirwa mumuviri uye zvemakemikari zvivako kwemapurotini, matsime avo, chaivo basa, uye vamwe, kazhinji asingashumbi, zviratidzo.

Saka, voga globular uye fibrous, hydrophobic (insoluble) uye hydrophilic (soluble) zvinhu. Kupesana iyi inobva physico-namakemikari ehupfumi of yeimwe. Zvichienderana panobva yoga mapuroteni ari huta rinenge serum, tsandanyama, uye vamwe. Kunewo kwemabhakitiriya, mhuka uye muriwo yeimwe. Maererano zvipenyu basa voga -hormones mapuroteni, makemikari, mapuroteni, contractile uye STRUCTURAL mapuroteni, antibodies, uye vamwe. Zvinofanira kucherechedzwa kuti pane zvimwe yeimwe risingagoni anonzi chero pamusoro mapoka. Izvi yokusakwana wegadziriro kupatsanura uye ane kusiyana aakatipa pamusoro mapurotini pachavo.

Ko yakakamurwa remubatanidzwa mune zvakaoma (proteid) uye nyore (mapurotini). Simple mapuroteni ndivo chete amino asidhi Polymers. Complex yeimwe, kuwedzera amino asidhi residues, uye ane asiri mapuroteni activation.

Muchitokisi chimwe nechimwe pane zviuru Organic dzakakwirira samolecular yeimwe. Nokuda chokuti munguva upenyu muviri, izvi zvinhu vaparadzwa tichikufunga, sero anofanira kumushandisira kuramba kwetunhu mapuroteni kuvakazve organelles dzavo, membranes nezvimwe zvinoriumba. Pamwe huru iyi nhamba masero anopa paumbwe Organic yeimwe muviri wose. In ichi "kugadzirwa" vari kuroorana, somuenzaniso, masero ari kwemakemikari anobudiswa mumasero iyo inokonzera mahormone. Apo mapuroteni usage ane mukuru zvikuru.

Pfungwa yeimwe kunoda simba mari. Source kupa kwete chete mapuroteni usage, asi zvose cellular pezvakaitwa ndiyo ATP.

Zvinofanira kucherechedzwa kuti dzakasiyana-siyana mashandiro uye zvinangwa yeimwe akaumba maererano vanonyanya maumbirwo - kutevedzana kuti amino asidhi ari Morekuru. Nhaka umboo hunotsigira chikuru mapuroteni mamiriro akanyudzwa mukati nucleotide cheni morekuru reDNA. Kuti mugove deoxyribonucleic acid, iro rine mashoko pamusoro amino iine acid kutevedzana kwezviitiko remubatanidzwa inonzi zviratidzo.

mapuroteni usage anotora nzvimbo pamusoro ribosomes iri cytoplasm muchitokisi. The cytoplasm kubva musimboti mashoko sechivako mukomboni riri muchimiro mRNA (mutumwa RNA). Nokuti kwetunhu mamorekuru uye RNA kunoitika "unwinding" (despiralization) DNA nharaunda. Zvakazoitwa muitiro paruchaitika nheyo complementarity. Kushandisa makemikari kuti DNA cheni iri synthesized RNA mamorekuru.

The cytoplasm inofanira iine dzakananga iine amino acids. It zvinodiwa mapuroteni usage. Inotungamirwa amino acids izvi imhaka cleavage pamusoro dzinodyiwa Organic yeimwe. Uyezve, amino asidhi kuwana pane zvakananga kwetunhu chikamu (the ribosome), vakati kuda imwe kuchinjwa RNA (tRNA).
