Cinnamic acid waa iskudhis dabiici ah oo leh caanaha C6H5CH=CHCOOH.Waa iskudhis crystalline cad oo wax yar ku milmay biyaha, oo si xor ah ugu milmaya dareerayaal badan oo dabiici ah.Waxa loo kala saaraa sidii karboksylic acid aan saturated ahayn, waxay si dabiici ah ugu dhacdaa tiro dhir ah.Waxay u jirtaa sida cis iyo trans isomer labadaba, in kasta oo kan dambe uu aad u badan yahay.

Cinnamic acid waa dhex dhexaad u ah biosynthesis ee alaabooyinka dabiiciga ah ee badan oo ay ka mid yihiin lignolsto lignin iyo lignocellulose, flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, iyo phenylpropanoids.biosynthesiskeeda waxaa lagu sameeyaa ficilka enzyme phenylalanine ammonia-lyase (PAL) ee phenylalanine.

Cinnamic acid waa horudhac u ah isku-darka tiro badan oo walxaha dhirta ah, oo ay ku jiraan lignin, tannins, flavonoids, pigments, qaybo badan oo ka mid ah qaybaha dhadhanka ee dhir udgoon, iyo alkaloids kala duwan, sida morphine iyo colchicine.

Isticmaalka:

Cinnamic acid waa walax muhiim ah sababtoo ah waxaa si weyn loogu isticmaalaa cadarka, cuntada, sawir qaadista, polymer iyo warshadaha dawooyinka, iyo sidoo kale daraasadaha kiliinikada iyo sunta.Ilaa hadda, habab badan ayaa la soo sheegay si loo go'aamiyo, sida titrimetry, kala duwanaanshaha-pulse polarography, spectrophotometry, spectrometry mass, HPLC, chromatography capillary electrokinetic, electrophoresis capillary, chromatography gaaska iyo chromatography dareere.Si kastaba ha ahaatee, waxaa jira faa'iidooyin badan oo ku saabsan hababkan, sida wakhtiga jawaabta dheer, isticmaalka reagent, qalliin adag, iwm.

1. Dhadhanka iyo udgoonka

Waxa loo isticmaali karaa isku dhafka udgoonka ee saabuunta, shambooyinka, budada dhaqida, iyo waxyaalaha la isku qurxiyo ee maalinlaha ah.Ashitada Cinnamonic waxaa loo isticmaalaa dhadhanka tufaaxa, dhadhan cherry, dhadhanka miraha, iyo udgoonka ubaxa.Waxay leedahay saamaynta ay ku joojinayso samaynta tyrosinase madow, waxay leedahay saameyn gaar ah oo ku saabsan fallaadhaha ultraviolet, waxay ka dhigi kartaa dhibco bunni khafiif ah ama xitaa way baaba'aan, waana mid ka mid ah maaddooyinka lagama maarmaanka u ah muraayadaha qorraxda sare.Cinnamic acid lafteedu waa nooc ka mid ah xawaashka, kaas oo leh saameyn wanaagsan oo udgoon.Inta badan waxaa loo isticmaalaa sida alaabta ceeriin ee udgoonka, taas oo ka dhigaysa udgoonka udgoonka ugu weyn.

2. Warshadaha dawooyinka

Warshadaha dawooyinka, waxa loo isticmaali karaa dawo muhiim u ah isku-dhafka iyo daawaynta cudurada wadnaha.Waxa loo isticmaali karaa sidii wadne-ilaa-wadnaha iyo wadnaha-wadnaha, iyo sidoo kale chlorpheniric acid synthetic iyo cinnamyl piperazine.Waxaa loo isticmaali karaa in lagu sameeyo "Xin Kean", suuxinta maxalliga ah, fungicides, hemostasis.Daawooyinka, iwm.Inta badan waxaa loo isticmaalaa xinjirowga maskaxda, arteriosclerosis maskaxda, halbowlaha halbowlaha cirrhosis iyo cudurrada kale.Waxay leedahay saameyn weyn oo ka hortag ah oo ku saabsan kororka unugyada adenocarcinoma ee sambabada.

3. Isku-dhafka dabiiciga ah

Marka la eego isku-darka kiimikooyinka organic, cinnamic acid waxaa loo isticmaali karaa sidii wakiilka sii daynta joogtada ah ee xaashiyaha galvanized, qaboojiyaha kulaylka ee polyvinyl chloride, crosslinker for polyurethane, olol dib u dhigista hydantoin iyo polycaprolactam, iyo falanqeeyaha kiimikada.Sidoo kale waa reagent go'aaminta kala soocida uranium iyo vanadium;sidoo kale waa alaabta ceeriin ah ee ugu muhiimsan ee nooca taban ee resins.Ester-ka ugu weyn ee lauric acid synthetic, polyvinyl alkohol cinnamate, ethyl ethoxy cinnamate iyo resin epoxy leh cinnamate pendant.Waxaa loo isticmaalaa balaastikada, waxaa loo isticmaali karaa sidii kulaylka qaboojiyaha PVC-ga, ka-hortagga caaryada iyo carfiye si loo nadiifiyo, sidoo kale waxaa lagu dari karaa caag iyo xumbo si loo sameeyo kabo qurxinta iyo maro-gashiyada.Waxa kale oo loo isticmaali karaa suufka iyo fiilooyinka synthetic ee kala duwan, maqaar iyo rinji.Kahortagga caariyaysiga alaabada sida suufka kabaha iyo gogosha cawska.
