Iimpawu kunye nemisebenzi asidi acid

acid - izinto zokwakha ezingundoqo nayiphi esiphilayo. Ngemvelo yazo, ukuba izinto zezityalo zaseprayimari nitrogen, apho kuhlelwe ukusuka emhlabeni. Isakhiwo kunye nomsebenzi iiprothini kunye acid zixhomekeke ukwakhiwa kwawo.

Ubume acid

molecule ngalinye carboxyl kunye ngomdla amaqela ayo, abaqhagamshelwe olukhulu. Ukuba acid acid iqulethe 1 carboxyl,-acid 1 iqela kobume bayo bangonakala echazwe kwifomula eboniswe ngezantsi.

asidi acid abe mnye iacid omnye obrak iqela call monoaminomonokarbonovymi. Eziphilayo kwakhona kuhlelwe acid, isakhiwo kunye nemisebenzi ezo anoxanduva amaqela 2 carboxyl, okanye amaqela acid 2. acid equlathe amaqela carboxyl mabini anamnye acid ekubhekiswe monoaminodikarbonovymi nokuba ezimbini ngomdla carboxyl, no-1 - diaminomonocarboxylic.

nabo ayashiyana isakhiwo R. zomgquba olukhulu ngamnye kubo igama layo kunye nesakhiwo. Ngenxa yoko, le ezahlukeneyo acid umsebenzi. Ubukho kwamaqela acid kunye obrak ukuqinisekisa reactivity yalo phezulu. La maqela amino oxhulumene ukwenza i Polymer - protein. Proteni nezaziwa ngokuba polypeptides ngenxa nesakhiwo sayo.

acid ukwakha

zinemoletyhule protein - nomxokelelwane inqwaba okanye amakhulu asidi acid. Iiproteni kwahluka kumafa, inani kunye umyalelo asidi acid, kuba inani edibeneyo amacandelo phantse ongapheliyo-20. Ezinye zazo yonke ukwakhiwa asidi kubalulekile acid, abanye ngaphandle omnye okanye ngaphezulu. Individual acid Isakhiwo acid abamisebenzi yabo iyafana kwiiproteni omzimba womntu akukho ezisetyenziswa njengokutya, njengoko enyibilikayo kancinci yaye musa gqiphu iphecana zesisu. Ezi zinto nail protein, iinwele, iwulu okanye iintsiba.

umsebenzi acid ayikwazi nemikhuba. Ezi zinto ke ukutya iphambili kwizidlo kwabantu. Ntoni na acid? Bona ukwandisa ukukhula kwezihlunu kwaye womeleze amalungu kunye nemisipha, balungise kwinyama ezonakeleyo emzimbeni kwaye bathatha inxaxheba kuzo zonke iinkqubo ezikhoyo emzimbeni womntu.

asidi kubalulekile acid

Kuphela izongezo okanye iimveliso ukutya ukufumana i asidi kubalulekile acid. Umsebenzi ekubunjweni amalungu esempilweni, izihlunu enamandla, iinwele elihle kubaluleke kakhulu. Ezi acid ziquka:

• phenylalanine;
• lysine;
• threonine;
• methionine;
• valine;
• leucine;
• tryptophan;
• histidine;
• isoleucine.

kubalulekile amino acids umsebenzi

Le iibhloko ukwenza imisebenzi ebalulekileyo kuzo zonke iseli zabantu. Awabonakali de ngenisa emzimbeni ngokwaneleyo, kodwa ukunqongophala kwabo kakhulu kwehlisa ukusebenza yonke eziphilayo.

1. Liqala Valine izihlunu, kuba ngowona mthombo wamandla.
2. Histidine kuphucula igazi, ukumimitheka nokukhula izihlunu, kuphucula ukusebenza amalungu.
3. Isoleucine kunceda ukwenza mpilo. Ilawula inani iswekile egazini, kwandisa amandla yomntu, unyamezelo.
4. Leucine komeleza inkqubo yomzimba yokuzikhusela, iqwalasela inqanaba iswekile kwi leukocytes egazini. Ukuba inqanaba leukocyte eliphezulu kakhulu, oku kuphungula iindawo zolondolozo imizimba yabo inxibelelanisa ukuphelisa komtshiso oko.
5. Lysine kunceda kwi ukufunxeka calcium, eyakhela kwaye kuqinise amathambo. Inceda ukwenziwa collagen, iphucula ubume iinwele. Kuba abantu, lo steroid elihle njengoko linceda izihlunu nokunyusa virility.
6. Methionine normalizes inkqubo yokwetyisa wesibindi. Ngenela kwi yokuwa amafutha, osusa isifo intsasa abasetyhini abakhulelweyo, kwamnceda iinwele.
7. Threonine kuphucula nokusebenza phecana zesisu. Oku kuphucula inkqubo yomzimba yokuzikhusela, inxaxheba ekudalweni collagen kunye elastin. Threonine nqanda isimemezelo kwamafutha esibindini.
8. Tryptophan inoxanduva lokuchukumiseka abantu. Ikhupha serotonin - hormone lolonwabo, oko normalizes ukulala, kuphucula isimo. onombilini Tames, uthando ichaphazela izihlunu intliziyo yegazi.
9. Phenylalanine kusetyenziswa amaza samaza evela kwiiseli zemithambo kwi ingqondo entloko. Oku kuphucula isimo, kthen onombilini mpilweni, iphucula inkumbulo, kwandisa ubuntununtunu kunye kunciphisa intlungu.

Ukuswela asidi ebalulekileyo acid kukhokelela abanjwe ukukhula, ukuphazamiseka pathways, ukwehla kobunzima bomzimba.

acid yokuchitha

Ezi acid, isakhiwo kunye nemisebenzi apho ziveliswa umzimba:

• arginine;
• alanine;
• asparagine;
• glycine;
• proline;
• taurine;
• tyrosine;
• glutamate;
• serine;
• glutamine;
• ornithine;
• cysteine;
• carnitine.

yokuchitha amino acids umsebenzi

1. Cysteine ususa izinto eziyityhefu inxaxheba ekudalweni ulusu kunye izihlunu zomzimba, i antioxidant yendalo.
2. Tyrosine kunciphisa Ukudinwa ngokwasemzimbeni, ikhawulezisa nethe, ephelisa xi kunye nokudakumba.
3. Alanine isetyenziswa ekukhuleni imisipha, njengomthombo wamandla.
4. Aspartic acid kwandisa ukutya kwaye yehlise ukuyilwa ammonia kwi imithwalo eliphezulu.
5. Cystine ishenxisa intlungu konzakale nemisipha kunye namalungu.
6. Glutamic acid linoxanduva umsebenzi kwengqondo, ngexesha amandla elide emzimbeni iba glucose ukuba ukunika amandla.
7. Glutamine ibuyisela izihlunu, kuyenza sifo, ikhawulezisa nethe, uqinisa ingqondo kwaye uvelisa hormone nokukhula.
8. kufuneka Glycine imisipha, ukwetyisa nenqatha, uzinzise uxinzelelo lwegazi kunye iswekile egazini.
9. Carnitine okunamafutha acid eshenxela iiseli apho cleavage lwabo kwenzeka xa kuphuma amandla, ibangela ukutsha ezityebileyo kwemfuneko kunye namandla eyenziwe.
10. Ornithine uvelisa hormone nokukhula, ukubandakanyeka Umchamo ukwakheka, lusicande esiti ngamanqatha inceda uphuhliso insulin.
11. Proline kwenza imveliso collagen, kuyimfuneko ukuba nemisipha kunye namalungu na.
12. Serine kuphucula kwamajoni omzimba kwaye uvelise amandla ezifunekayo ukutya ngokukhawuleza okunamafutha acid kunye nokukhula kwezihlunu.
13. Taurine iyonakala amanqatha, uphakamisa ukuxhathisa komzimba, synthesizes ityuwa enyongweni.

Protein kunye neempawu zayo

Iiproteni, okanye weeproteni - eliphezulu iikhompawundi ubunzima ngemolekyula kunye initrogen. Igama elithi "protein", okokuqala kuboniswe Berzelius ngo-1838, livela kwisiGrike, lithetha "zaseprayimari" ezivakalisa iiproteni ixabiso ephambili indalo. Ezahlukahlukeneyo neeproteni kuvumela ukuba ubukho inani enkulu izidalwa eziphilayo, yibhaktheriya emzimbeni womntu. Ewe ezinkulu kakhulu kunezinye macromolecules, ekubeni iiprotheni - sisiseko iseli ophilayo. I-malunga nama-20% ye-ubunzima lomzimba womntu, ngaphezulu kwama-50% ye ubunzima yeseli owomileyo. Oku kuchaza ezahlukeneyo iiprothini iimpawu amabini asidi ezahlukeneyo acid ukunxibelelana nabanye nokudala zinemoletyhule Polymer.

Iimpawu ezibalaseleyo kwiproteni - ukukwazi self-ukudala isakhiwo ezithile azalwa lwendawo iproteni ethile. Ngokutsho isakhiwo eekhemikhali iiprotheni - yi biopolymers ngemixokelelwane peptide. Kuba imichiza ukwakhiwa iiprotheni uphawu rhoqo isiqulatho avareji nitrogen - malunga ne-16%.

Life, kwakunye nokukhula nophuhliso ephilayo akunakwenzeka ngaphandle umsebenzi we-asidi zeproteni acid ukwakha iiseli ezintsha. Iiproteni ayikwazi indawo zezinye izinto, indima yabo emzimbeni womntu kubaluleke kakhulu.

Imisebenzi ye iiprotheni

Imfuneko weeprothini imisebenzi enjalo:

• kuyimfuneko ukuba ukukhula kunye nophuhliso, njengoko yengundoqo i zokwakha izinto iiseli ezintsha;
• Ilawula nethe, ngexesha apho amandla uyakhululwa. Emva kokudla ukunyuka izinga metabolic, umz, ukuba ukutya ubunjwe carbohydrate lokugaya kwandiswa yi-4% xa iiproteni kwi - 30%;
• ukulawula ukulingana amanzi emzimbeni, ngenxa hydrophilicity wayo - ukukwazi kutsala amanzi;
• ukuqinisa amajoni omzimba ukuba nokulungelelanisa antibodies ezikhusela kusulelo kunye nokuvala isisongelo sifo.

Iimveliso - imithombo protein

Izihlunu kunye ngamathambo omntu kuquka eziphilayo, leyo ngaphezulu kobomi le ayikasebenzi kuphela, kodwa kuhlaziywa. Isazama yokulimala, ihlala isebenza kunye namandla. Ukuze benze oku, ukuba zifuna izondlo ezithile kakhulu. Ukutya kunika umzimba kunye amandla ukuze zonke iinkqubo, kuquka umsebenzi wokulungisa izihlunu, ukukhula kunye kwithishyu. A protein emzimbeni kwaye enokusetyenziswa njengomthombo wamandla kunye njengoko kwakhiwe.

Ngoko ke kubaluleke kakhulu ukuba bagcine ukusetyenziswa lakhe imihla ekutyeni. Protein eninzi ukutya: inkuku, pipi, ham ibhityile, inyama yehagu, inyama yenkomo, intlanzi, Shrimp, neembotyi, neentlumaya, Bacon, amaqanda, nuts. Zonke ezi mveliso unike umzimba protein unike amandla ubomi.
