Protheine Sebopeho: Seo re se tsebang ka eena?

E o tsejoa hore lihaha-'mele tse hlokahalang 'me karolo e khōlō ea leha e le efe e phelang e phelang. Ho ba ba nang le boikarabelo ba ho metabolism le matla a ho sokoloha, e leng e inextricably amahanngoa le hoo e batlang e dithulaganyo ka 'ohle. Dry taba meholo. boholo ba lisele le makala ohle a batho le liphoofolo, 'me tse fetang 50% ea microorganisms tsohle, haholo-holo a qapa ea liprotheine (40% ho 50%). 'Musong dimela bona boima itseng bapisoa le boleng ka karolelano e ka tlaase ho moo, le phoofolo e - ho feta. Leha ho le joalo, le lik'hemik'hale tsa protheine ho batho ba bangata e ntse e le e sa tsejoeng. A re ke re a boela a hopola se ka hare tsena phahameng polymers tlhaho.

protheine Sebopeho

ntho ena ka karolelano ba le ka 50-55% k'habone, 15-17% naetrojene, 21-23% oksijene, 0.3-2.5% sebabole. Ho phaella ho dikarolo tsena tsa motheo, ka linako tse ling ka liprotheine kenyeletsa thepa ea motheo e lekana e tlaase haholo. Ka holim'a tsohle, hona phosphorus, tšepe, iodine litareng e, koporo le itseng micro- tse ling le macronutrients. Makatsang ea naetrojene mahloriso o na le kamehla phahameng ka ho fetisisa, ha diteng tsa dikarolo tse ding senotlolo 'na tsa fapana. A hlalosa le protheine sebopeho, hakaalo re lokela ho hlokomela hore ho ke ke e polymer tsoeng haha ea litlhaka kahare amino acid e ka moralo wa tseo tharollo ea metsi ka ph se nke lehlakore ka tsela e ngata akaretsang ho e ngotsweng ka NH3 + CHRCOO-.

Pakeng tsa tsena "diboloko tse ahang" ba ikopanya le e amide tlamo e pakeng tsa lihlopha tsa carboxyl le Amine. Tsohle tsa tlhaho o ile a senola ka likete liprotheine fapaneng. sehlopha sena sa tse lisireletsi, potlakisang tsebetso ea lik'hemik'hale, li-hormone tse ngata le lintho tse ling tse mafolofolo nakong likokoana-hloko. Ho makatsang ke hore, ho sa tsotellehe ho fapafapana ena kaofela protheine sebopeho ka kenyeletsa tse sa feteng tse 30 fapaneng amino acid, 20 oo e ratoang ka ho fetisisa. Batho, ba ile ba fumana 22 feela, ba bang kaofela ke feela e sa ananelang le excreted tsoa. Robeli-amino acid tsa sehlopha sena e nkoa e le ba bohlokoa haholo. Ho leucine, methionine, isoleucine, lysine, phenylalanine, tryptophan, threonine le valine. Ba 'mele ea rōna e ke ke ea synthesize tsa bona, empa ka lebaka la ho noa bona hlokahalang ho tswa ho ka ntle. Tse setseng (taurine, arginine, glycine, carnitine, asparagine, histidine, cysteine, glutamine, alanine, ornithine, tyrosine, proline, serine, cystine), e ka ba ho bopa le nosi. Ka lebaka leo, acid tsena amino ba nkoa e le fapanyetsana sehlopha. Ho itšetlehile ka hore na sehlopha sa pele sa nang le protheine e, hammoho le lengolo la sona la absorption ka 'mele, le protheine e arotsoe phahameng sehlopheng le tlaasana. Ka karolelano letsatsi le letsatsi tshebediso ya lebelo la dintho ho batho ba itšetlehile ka ho mefuta e fapaneng ho tloha dikgerama 1 ho 2 ka kilogerama ea boima ba 'mele. Ka nako e tšoanang batho sedentary lokela khomarela e qetellong e ka tlaase ea mefuta e fapaneng hona le sporstmenov - holimo.

Tsela ea ho ithuta sebōpeho sa protheine

Bakeng sa ho ithuta lintho tsena ke haholo-holo e sebediswa hydrolysis mokhoa. The letsitseng protheine thahasella e halefile ka acid e hlapolla hydrochloric (6.10 Mol / litha e le nngwe) ka mocheso oa ho tloha 100 ho sa 1100? C? C. Ka lebaka leo, ho putlama ka motsoako oa amino acid hore ba se ba ntse ho fana ka-amino acid motho. Hona joale, ho sa and analysis ditirisanommogo tsa protheine teko sebediswa pampiri, 'me Ion phapanyetsano chromatography. Ho na le ke esita le ea khethehileng jarolla ka ho iketsa analyzers tse bonolo ho hlalosa hantle eo-amino acid tse hlahisoang ke ho bola.
