Features le mesebetsi ya-amino acid

-amino acid - ka sehloohong thepa ea mohaho le mokhoa oa leha e le efe e phelang e phelang. Ka tlhaho ea bona, ba ile ba ba le ka sehloohong nitrogenous dimela thepa, tse tsa maiketsetso mobung. Sebopeho le mosebetsi wa liprotheine le-amino acid itshetlehile sebopeho bona.

Sebōpeho sa amino acid e

E mong le e molek'hule o carboxyl le Amine lona lihlopha, tse amanang ho tse khōlō. Ha amino acid e na le 1 carboxyl, 1-amino sehlopha sa sebopeho lona ka a hlalosa ka ho moralo o balletsweng e bontšitsoeng ka tlaase mona.

-amino acid tse 'ngoe asiti le mong alkaline sehlopha pitso monoaminomonokarbonovymi. tse phelang li hape tsa maiketsetso -amino acid, sebopeho sa le mesebetsi ea eona e na le boikarabelo bakeng sa lihlopha carboxyl 2, kapa lihlopha tsa amino 2. -amino acid tse nang le lihlopha tsa carboxyl tse peli le e mong amino hlalositsweng monoaminodikarbonovymi le ho ba le tse peli tse carboxyl Amine, 'me 1 - diaminomonocarboxylic.

ba boetse ba fapana ka sebopeho sa manyolo khōlō R. mong le e mong oa bona o na le lebitso la eona 'me a sebopeho. Ka lebaka leo, tse fapa-fapaneng-amino acid mosebetsi. Ho ba teng ha lihlopha acid e le alkaline etsa bonnete ba reactivity lona phahameng. lihlopha tsena amino tse amanang ho theha e polymer - protheine. Liprotheine le tsona di bitsoa polypeptides ka lebaka la sebopeho lona.

-amino acid le boitsebiso bo na le mohaho

protheine molek'hule - ketane ea tse ngata kapa tse makholo-amino acid. Liprotheine fapana ka sebopeho, palo le taelo ea-amino acid, hobane palo ea tlhakantsuke ya dikarolo 20 ya hoo e batlang e ke keng ba lekanngoa. Ba bang ba bona ba na le sebopeho kaofela ba acid bohlokwa amino, ba bang ba etsa ntle le e 'ngoe kapa ho feta. Motho amino sebopeho asiti bao mesebetsi tse tšoanang le liprotheine tsa 'mele oa motho e sa sebelisoa e le lijo, e le hanyenyane qhibilihang ka har'a' me u se ke ua a arola pampitšana gastrointestinal.
