Butyric acid: Properties thiab cov kev siv

Carboxylic acid - organic biosoedineniya tias nyob rau hauv cov qauv ntawm lawv cov molecules muaj ib los yog ntau tshaj carboxyl pawg. Cov chav kawm ntawv ntawm carboxylic acids combines ib tug zoo tus naj npawb ntawm cov organic tebchaw uas muaj nyob rau hauv lawv cov qauv. Nyob rau hauv tas li ntawd mus rau cov pab pawg, yuav ua tau tam sim no thiab lwm yam kev haumxeeb pawg neeg uas txiav txim zog uas yog tsis yam ntxwv ntawm tebchaw xwb carboxyl pawg nyob rau hauv lub lwg me me ntawm carboxylic acids.

Monobasic nyeem carboxylic acid - derivatives ntawm alkanes nyob rau hauv lub molecule, ib tug hydrogen atom yog pawg nrog COOH. Tej tebchaw no tej zaum kuj raug xa mus aliphatic acids los yog fatty, xov tooj, vim ib txhia ntawm lawv cais los ntawm roj hydrolysis khoom.

Carboxylic acids yog lawm nyob rau hauv lub dawb (e.g., formic - nyob rau hauv tsis muaj kua kab, thiab tso zis hws ntawm cov tsiaj, nettles, ib co txiv hmab txiv ntoo thiab zaub) thiab txhua yam (piv txwv li, dua fatty acid li triatsilgitserolov) lub xeev. Dua fatty acids tau los ntawm hydrolysis ntawm nruab nrab lub sibhawm thiab roj. Feem ntau cov organic acids uas yog npaj los ntawm txoj kev ntawm cov organic synthesis.

Isobutyric acid yog ua thaum lub sij hawm oxidation ntawm lub isobutyl haus dej cawv. Rau oxidation isobutanol siv alkaline poov tshuaj permanganate tshuaj. Nyob rau hauv laboratory tej yam kev mob, lub acid kuj yuav npaj los ntawm cov oxidation uas isobutyraldehyde. Nyob rau hauv tej yam ntuj tso tej yam kev mob, nws yog muaj nyob rau hauv cov roj thiab arnica cov hauv paus hniav. Cov acid siv nyob rau hauv qhov siv thiab ua perfumes, plasticizers rau zus tau tej cov varnishes, emulsifiers.

Thawj homologs (formic acid, acetate, propionic thiab butyric acid), nyeem monobasic carboxylic acid muaj ib tug pungent tsw, tov zoo nrog H2O nyob rau hauv txawv ratios. Cov nram qab no peb cov neeg sawv cev - acid nrog ib tug unpleasant tsis hnov tsw, tag nrho cov so - khib nyiab.

Butyric acid - kua nrog ib tug pungent tsis kaj siab tsw, boils ntawm 163,5 C. Nws yog pom nyob rau hauv ib tug dawb hauv lub xeev (hws) thiab nyob rau hauv daim ntawv ntawm cov esters (glycerides butter).

Butyric acid: mis - S3N7SOON

Txij li thaum hais tias compound muaj ib carboxyl pab pawg neeg nyob rau hauv nws cov qauv, nws yog hais txog monobasic nyeem fatty acids. Butyric acid yog ua vim butyric fermentation ntawm carbohydrates nyob rau hauv kev ua lag luam - lub oxidation ntawm n-butane los yog butyraldehyde. Qhov no acid yog siv nyob rau hauv qhuav ntawm uas muaj ntxhiab tshuaj, synthesis ntawm cov tshuaj, zus tau tej cov plasticizers, cellulose atsetilbutirata etc.

Qhov tsawg molecular yuag acids yuav tau daim thaum lub sij hawm kab mob synthesis nyob rau hauv txoj hnyuv loj. Ib tug ntawm cov tseem ceeb tshaj plaws uas tsis muaj molecular yuag acids uas yog tsim nyob rau hauv cov hnyuv, yog butyric acid. Ncav proven correlation ntawm cov tshaj ntawm tsawg molecular yuag acids thiab lub zaus ntawm exacerbations thiab colonic cov kab mob (ulcerative mob plab, malignant neoplasms). Butyric acid - lub ntsiab nquag cov khoom siv rau epithelial hlwb, nws txhawb plab hnyuv homeostasis. Cov acid exhibits anti-carcinogenic thiab anti-inflammatory kev txiav txim uas muaj feem xyuam rau lub qab los noj mov, tsis pub txoj kev loj hlob ntawm oxidative kev nyuaj siab.

Rau cov kev kho mob ntawm tej yam kab mob cov kws kho mob uas siv cov acid rau kho lub hom phiaj. Hais tias acid yog chiv nkag tau rau hauv lub cev rectally vim hais tias raws li qhov ncauj thawj coj gidrolizirovyvalas nws sai sai nyob rau hauv lub plab. Tus kho nyhuv nyob rau hauv cov ntaub ntawv no yog ib tug muaj hnub nyoog. Txawv teb chaws cov kws txawj tau tsim ib tug tshiab ntau npaum daim ntawv ntawm bioactive tshuaj rau qhov ncauj noj. Tus qauv ntawm cov tshuaj muaj sodium butyrate thiab plhaub polymer. Txawm li cas los, cov tshuaj no muaj ib tug uas tsis muaj hauj lwm zoo. Qhov zoo tshaj plaws kho nyhuv twb tau nrog npaj uas muaj xws li calcium butyrate thiab prebiotic (txhais tau tias "Zakofalk").
