Kodi ma organic acid ndi chiyani?

Organic acids" amatanthauza ma asidi onse otchedwa carboxylic acid omwe amamangidwa pa mafupa a kaboni omwe amatha kusintha momwe mabakiteriya amagwirira ntchito, zomwe zimapangitsa kuti pakhale zovuta za metabolic zomwe zimalepheretsa kuchulukana ndikupha.

Pafupifupi ma organic acid onse omwe amagwiritsidwa ntchito pazakudya za nyama (monga formic acid, propionic acid, lactic acid, acetic acid, sorbic acid kapena citric acid) ali ndi mawonekedwe aaphatic ndipo ndi magwero amphamvu a maselo. Motsutsana,benzoic acidimamangidwa pa mphete zonunkhiritsa ndipo imakhala ndi metabolic komanso mayamwidwe osiyanasiyana.

Kuphatikizika kwa ma organic acid pamiyezo yoyenerera pazakudya za ziweto kumatha kukulitsa kulemera kwa thupi, kusintha kusintha kwa chakudya ndikuchepetsa kufalikira kwa tizilombo toyambitsa matenda m'matumbo.

1, chepetsani pH yamtengo ndi kusungitsa mphamvu muzakudya komanso antibacterial ndi antifungal zotsatira.

2, potulutsa ayoni wa haidrojeni m'mimba kuti achepetse mtengo wa pH, potero kuyambitsa pepsinogen kupanga pepsin ndikuwongolera digestibility ya mapuloteni;

3. Kuletsa mabakiteriya a gram-negative m'matumbo a m'mimba.

4, ma metabolites apakatikati - amagwiritsidwa ntchito ngati mphamvu.

Kuchita bwino kwa organic acid poletsa kukula kwa tizilombo toyambitsa matenda kumadalira mtengo wake wa pKa, womwe umafotokoza pH ya asidi pa 50% mu mawonekedwe ake osagwirizana komanso osagwirizana. Chotsatirachi ndi momwe ma organic acid ali ndi antimicrobial properties. Ndi pamene ma organic acid ali mu mawonekedwe awo osagwirizana kuti amatha kudutsa makoma a mabakiteriya ndi bowa ndikusintha kagayidwe kawo kamene ali ndi mphamvu zowononga tizilombo toyambitsa matenda. Choncho, izi zikutanthauza kuti mphamvu ya antimicrobial ya organic acid ndi yapamwamba pansi pa acidic (monga m'mimba) ndipo imachepetsedwa pa pH ya ndale (m'matumbo).

Choncho, ma organic acid omwe ali ndi pKa yapamwamba ndi ma asidi ofooka komanso mankhwala oletsa tizilombo toyambitsa matenda m'zakudya chifukwa cha kuchuluka kwa mitundu yosagwirizana yomwe ilipo mu chakudya, yomwe ingateteze chakudya ku bowa ndi tizilombo toyambitsa matenda.

Acidified glyceride

M'zaka za m'ma 1980, wasayansi waku America Agre adapeza puloteni ya cell membrane yotchedwa aquaporin. Kupezeka kwa ngalande zamadzi kumatsegula gawo latsopano la kafukufuku. Pakali pano, asayansi apeza kuti aquaporins amapezeka kwambiri mu nyama, zomera ndi tizilombo.

Kudzera mu kaphatikizidwe wa asidi propionic ndi asidi butyric ndi glycerol, α-monopropionic asidi glycerol ester, α-monobutyric asidi glycerol ester, ndi kutsekereza mabakiteriya ndi bowa glycerol njira, kusokoneza mphamvu zawo bwino ndi nembanemba mphamvu bwino, kotero kuti iwo kutaya mphamvu magwero, kutsekereza mphamvu kaphatikizidwe, ndi mabakiteriya ndi mabakiteriya kuletsa mphamvu ya mankhwala.
