Shikimic acid ( 3, 4, 5-trihydroxy-1-cyclohexene-1-carboxylic acid), lub ntuj organic compound, yog ib qho tseem ceeb nruab nrab hauv biosynthesis ntawm lignin. [1], aromatic amino acids (phenylalanine, tyrosine, thiab triptophane), thiab feem ntau alkaloids ntawm cov nroj tsuag thiab kab mob [2–4].
Cov tshuaj nruab nrab twg yog tsim nyob rau hauv txoj kev shikimic acid?
Shikimic acid txoj kev muab amino acids xws li phenylalanine thiab tyrosine uas yog siv rau cov protein synthesis thiab tseem ua haujlwm rau substrate rau theem nrab metabolite biosynthesis xws li phenolic acids (Ali, Singh, Shohael, Hahn, & Paek, 2006).
Qhov twg yog qhov ua ntej hauv kev sib txuas ntawm shikimic acid?
Phenylalanine thiab tyrosine yog cov precursors siv hauv phenylpropanoids biosynthesis. Tom qab ntawd cov phenylpropanoids yog siv los tsim cov flavonoids, coumarins, tannins thiab lignin. Thawj enzyme koom nrog yog phenylalanine ammonia-lyase (PAL) uas hloov L-phenylalanine rau trans-cinnamic acid thiab ammonia.
Qhov twg yog qhov khoom kawg ntawm txoj kev shikimic acid?
Ib tug ceg taw tes tseem ceeb yog chorismic acid, cov khoom kawg ntawm txoj kev shikimate. Txoj kev shikimate tau piav qhia hauv tshooj no, nrog rau cov yam ntxwv uas ua rau muaj kev sib txuas ntawm phenolic compounds hauv cov nroj tsuag.
Puas yog shikimic acid yog thawj lossis theem nrab metabolite?
Txoj hauv kev shikimic acid, ubiquitous nyob rau hauv cov kab mob thiab cov nroj tsuag, muab precursors rau lub biosynthesis ntawm thawj metabolitesxws li cov aromatic amino acids thiab folic acid.
