Pyruvic acid kanye nokusebenzisa kwayo njengendlela uyaxebuka

Uyazi ekhuthaza kwamakhemikhali ngaphansi kwegama "pyruvic acid"? Kubalulekile kakhulu umzimba womuntu ikhemikhali udlala indima ebalulekile izinqubo eziningi biosynthesis futhi ezitholakala ezintweni womuntu eziyishumi nemitshingo. Kuyinto organic keto acid. Futhi kanyekanye a carboxylic acid, futhi ketone, kodwa lasungulwa incike izimo inqubo kanye nezindawo. Njengoba acid, it yakha usawoti (pyruvates) kanye amides, kodwa kuvame kakhulu ukuba kusetshenziswe njengoba pyruvate.

Pyruvic acid kwenzeka ngesikhathi zamagama noma ukubhidliza amino acid. Kuyinto umkhiqizo ekupheleni umzimba glucose noma, ngokunembile, yenqubo glycolysis. Pyruvic acid - oluyisisekelo izinqubo eziningi umzimba ngamangqamuzana aphilayo. Uneziqu indima ekhethekile kwamakhemikhali ngoba kuyingxenye ebalulekile amaprotheni umzimba amaseli. Le asidi e kwezitho nezicubu kulo itholiwe. Ukushintsha inani yalo kwenzeka nezifo ezibucayi izinso, isibindi, beriberi, kodwa ikakhulukazi ngesikhathi nokuntuleka uvithamini B1. Kuyinto ekhona egazini labantu, futhi kuyinsakavukela salo 1 mg umchamo itholwa ngokuvamile 2 mg ketshezi.

Lapho wadalula oksijini, kungaba vula ku acetyl-coenzyme A, okuyinto isisekelo ukusabela lomjikelezo Krebs (ukuphefumula umjikelezo). Ngakolunye uhlangothi, uma hhayi umoya-mpilo ngokwanele, pyruvic acid is wajinge wanamatsela, futhi ngaleyo ndlela ukwakha acidosis acid (e izilwane), futhi i-ethanol (ezitshalweni). Sici Its liqukethe yokuthi i-asidi kuyinto umkhiqizo Lesisemkhatsini we cleavage ushukela ngendlela inqubo ukuvutshelwa oludakayo. Lapho ibekwe ku-isixazululo aqueous nge khona nembiliso, inqubo noqhekeko kwenzeka, futhi ngeke acetaldehyde futhi carbon dioxide.

Kuyini pyruvic acid? Formula ke ungaboniswa kanje: SN3SOSOON. Indlela ekukhiqizeni acid Ukushisa tartaric. Kukhona futhi ezinye izindlela: ngokusebenzisa nitrile ka acetyl chloride, pyrolysis ka tartaric acid noma hydroxy acid namachibi.

Yini-ke, uma sicabangela ke zibukeke? Okokuqala, iwuketshezi nge iphunga isici ka acetic acid. It amathumba ezingeni lokushisa + 165 ° C no-encibilikayo otshwaleni, amanzi kanye ether. Pyruvic acid, ifomula zazo SN3SOSOON uye wakwenza ufundwa ososayensi.

Kuye kwatholakala ukuthi inqwaba e izithelo ezisawolintshi futhi uju. Kukhona lolu hlelo lokusebenza wesimo esisodwa ezithakazelisayo, okuyinto chithi saka eminyakeni yamuva nje. Cosmetologist, wabizwa ngokuthi "pyruvic ikhasi," okuyinto efana ubisi okunye salicylic. Lolu hlobo uyaxebuka kungaba olukha phezulu noma okunzima kumthelela yabo. Isetshenziselwa lapho izinguquko ezihlobene nokukhula zisobala futhi zidinga ukwelashwa ngendlela eyingozi kakhulu. Lokhu kusebenza ngokuyinhloko imibimbi ezijulile, kanye ukuqina wendawo kwesikhumba.

Pyruvic uyaxebuka - lena isenzo ngempumelelo kakhulu nge-acid ezijulile, ungqimba papillary kwesikhumba. Kuvuselela fibroblasts ukuba i-collagen, mithambo ine-elastin kanye asidi i-hyaluronic, ngoba ukunikeza abasha, isikhumba ezikhangayo, okwenza ubuso bheka fresh futhi zigcinwe kahle kakhulu.

Beautician ngokuvamile esabela ebusweni peelings kusuka ukwelashwa 4 kuya ku-7 no-isikhawu emifushane (phakathi 7 no-14 izinsuku). Uyaxebuka naphakathi umfutho imodi kuhlukile kancane: kusuka ukwelashwa 2 kuya ku 4, igebe phakathi kwezingane okuyinto kakade azisizi ezingu-21 kuya ku-28. Qaphela ukuthi uma umfutho isilinganiso izinqubo isikhathi kuyadingeka ukuze isikhumba useluleme. Lokhu kwenzeka ngemva mayelana 4 izinsuku, futhi mhlawumbe kamuva, kuye ngohlobo isikhumba. Uma nezinqubo zithathwa ehlobo, ungakhohlwa ukusebenzisa ukuphuma kuya cream isikhumba elangeni emgwaqeni isihlungi okusezingeni eliphezulu.
