ʻO ka waika P-Hydroxycinnamic he mea kemika i loaʻa i kahi hui hydroxyl me nā waiwai antioxidant. ʻO ka melemele māmā a hiki i ka beige crystalline pauka me ka ʻala, hiki ke hoʻoheheʻe ʻia i ka methanol, ethanol, DMSO a me nā mea hoʻoheheʻe kūlohelohe ʻē aʻe, i loaʻa mai ka synthesis.
Hoʻohana
ʻO 4-Hydroxycinnamic acid ka hydroxy derivative o Cinnamic Acid me nā waiwai antioxidant. He mea nui ia o ka lignoscellulose. Hōʻike nā haʻawina e hiki i ka 4-Hydroxycinnamic acid ke hōʻemi i ka hopena o ka maʻi kanesa ma o ka hoʻemi ʻana i ka hoʻokumu ʻana o nā nitrosamines carcinogenic. Ua hōʻike ʻia kahi noiʻi hou e hiki i ka 4-Hydroxycinnamic acid ke hana ma ke ʻano he castrator kemika i loko o ka nalo ma o ka hoʻololi ʻana i ka hoʻopili ʻana o nā genes e pono ai no ka ulu ʻana o ka ovary. He mea maʻamau kēia pūhui i loko o ka pollen kahi mea nui o ka ʻai nalo hana, akā ʻaʻole ia i loaʻa i loko o ka mōʻīwahine bees'royal jelly.
Palapala noi
ʻO ka p-Hydroxycinnamic acid, ka mea i ʻike ʻia he p-coumaric acid, loaʻa mai ka hana o ka p-hydroxybenzaldehyde a me ka malonic acid. Hoʻohana nui ʻia ka P-hydroxycinnamic acid i nā mea ʻala a i ʻole he acidulant no nā mea inu, a me he antioxidant no nā aila. I ka ʻoihana lāʻau lapaʻau, ʻo ia ka mea maka o nā lāʻau lapaʻau he nui, e like me ka synthetic anti-adrenergic drug esmolol. Eia kekahi, hoʻohana pū ʻia ka p-hydroxycinnamic acid ma ke ʻano he acidifying agent i ka lāʻau lapaʻau a ma ke ʻano he sequestering agent i ka lāʻau lapaʻau, a me kahi intermediate kemika, e like me ka synthesis o kahi lāʻau expectorant hou Rhododendron; hoʻohana ʻia no ka hana ʻana o Kexinding, kahi lāʻau lapaʻau no ka mālama ʻana i ka maʻi maʻi maʻi. Intermediates, a hoʻohana ʻia i ka hana ʻana i nā anesthetics kūloko, fungicides a me nā lāʻau hemostatic; ʻo ia hoʻi ka hopena o ke kāohi ʻana i ka maʻi maʻi cervical. Ma ka mahiʻai, hoʻohana ʻia e hana i nā mea hoʻoulu ulu ulu, nā fungicides lōʻihi a me nā preservatives no ka mālama ʻana i nā huaʻai a me nā mea kanu. I loko o ka ʻoihana kemika, ʻo ka p-hydroxycinnamic acid he mea ʻono nui a me ka ʻala, hoʻohana nui ʻia e hoʻonohonoho i nā mea ʻala e like me nā cherries spicy, apricots, a me ka meli. Hoʻohana ʻia ia i ka hoʻomākaukau ʻana i ke kopa a me ka mea hoʻonaninani i ka ʻoihana kemika i kēlā me kēia lā. Ma nā mea hoʻonaninani, hiki i ka p-hydroxycinnamic acid ke keʻakeʻa i ka hana o tyrosinase monophenolase a me diphenolase, ka hopena o ka emi ʻana o 50% o ka hana monophenolase a me ka hana diphenolase, a hoʻohana ʻia i nā mea hoʻonaninani e kāohi i ka hana ʻana o ka melanin.
