Nkọwa ngwaahịa
Lactic acid bụ kemịkalụ kemịkalụ nke na-ekere òkè n'ọtụtụ usoro biochemical, nke a makwaara dị ka mmiri ara ehi, bụ ngwakọta kemịkalụ nke na-ekere òkè n'ọtụtụ usoro biochemical. Na anụmanụ, L-lactate na-emepụta mgbe niile site na pyruvate site na enzyme lactate dehydrogenase. (LDH) na usoro ịgba ụka n'oge metabolism nkịtị na mmega ahụ. Ọ naghị abawanye na ntinye uche ruo mgbe ọnụọgụ nke mmepụta lactate gafere ọnụego mwepụ nke lactate nke a na-achịkwa ọtụtụ ihe gụnyere: Ndị na-ebugharị Monocarboxylate, ntinye uche na isoform nke LDH na ikike oxidative nke anụ ahụ. Ọnụnọ nke lactate ọbara na-abụkarị 1-2 mmol / L na izu ike, mana ọ nwere ike ịrị elu karịa 20 mmol / L n'oge mgbatị siri ike. N'ime ụlọ ọrụ mmepụta ihe, nje bacteria Lactobacillus na-eme gbaa ụka Lactic acid, n'etiti ndị ọzọ. Nje bacteria ndị a nwere ike ịrụ ọrụ n'ọnụ; Acid ha na-emepụta bụ maka ire eze nke a maara dị ka caries. Na nkà mmụta ọgwụ, lactate bụ otu n'ime ihe ndị bụ isi nke lactate Ringer ma ọ bụ ngwọta Ringer's solution (CompoundSodium Lactate ma ọ bụ Hartmann's Solution na UK). Mmiri a na-agba n'ime ahụ nwere sodium na potassium cations, na lactate na chloride anions, na ngwọta na mmiri distilled na ntinye uche ka ọ bụrụ isotonic ma e jiri ya tụnyere ọbara mmadụ. A na-ejikarị ya eme ihe maka iweghachi mmiri mgbe ọbara nwụsịrị n'ihi mmerụ ahụ, ịwa ahụ, ma ọ bụ mmerụ ọkụ.

5. Natural lactic acid bụ ihe dị n'ime anụ ahụ na ngwaahịa mmiri ara ehi. Ọ nwere uto nke ngwaahịa mmiri ara ehi na ezigbo mgbochi microbial mmetụta. A na-eji ya eme ihe n'ọtụtụ ebe n'ịgwakọta cheese yoghurt, ice cream na ihe oriri ndị ọzọ, ma ghọọ onye na-ewu ewu na-edozi mmiri ara ehi;
6. Lactic acid ntụ ntụ bụ ntụ ntụ ntụ ntụ kpọmkwem maka mmepụta achịcha steamed. Lactic acid bụ acid fermented eke, ya mere ọ nwere ike ime achịcha pụrụ iche. Lactic acid bụ ihe na-achịkwa uto uto eke. A na-eji ya eme achịcha na achịcha na achịcha, achịcha, bisiki na nri ndị ọzọ esiri esi. Ọ nwere ike melite ogo nri ma nọgide na-agba agba. , ịgbatị ndụ shelf.
7. Ebe ọ bụ na L-lactic acid bụ akụkụ nke ihe na-eme ka anụ ahụ pụta, a na-ejikarị ya eme ihe dị ka ihe na-edozi ahụ maka ọtụtụ ngwaahịa nlekọta anụ ahụ.
