ʻO ka waika Palmitic (hexadecanoic acid inNomenclature IUPAC) he aʻakika momoname kahi kaulahao 16-carbon. ʻO ia ka mea maʻamausaturated fatty acidloaʻa i nā holoholona, nā mea kanu a me nā microorganisms. Konaʻano kimekiniʻo CH3(CH2)14COOH, a me kona lākiō C:D (ka huina o nā ʻātoma kalapona i ka helu o nā mea paʻa kalapona kalapona) he 16:0. He mea nui ia oʻaila pāmamai ka hua oElaeis guineensis(ʻaila pāma), e hana ana i ka 44% o ka nui o nā momona. ʻO ka ʻiʻo, ka paʻakai, ka pata, a me nā huahana waiu ʻē aʻe kekahi i loaʻa i ka palmitic acid, ka nui o 50-60% o ka nui o nā momona.
Ua ʻike ʻia ʻo Palmitic acid eEdmond Frémy(i ka makahiki 1840) ma kasaponificationʻO ka ʻaila pāma, ʻo ia ke kaʻina hana i kēia lā ke ala ʻoihana mua no ka hana ʻana i ka waikawa.Triglycerides(momona) maʻaila pāmahehydrolysede ka wai wela kiʻekiʻe a me ka hui ʻana o ka hopenahoʻoheheʻe ʻia.
Hana ʻia ka ʻakika Palmitic e nā ʻano mea kanu a me nā mea ola, maʻamau ma nā pae haʻahaʻa. Aia ma waena o nā meaʻai maʻamauwaiu,pata,pākī, a me kekahiʻiʻo, a ʻo kekahipata koko,ʻaila ʻoliva,ʻaila ʻaila soya, aʻaila pua lā.
ʻO ka waika Palmitic kahi momona momona i loaʻa mau i nā holoholona a me nā mea kanu. ʻO ia ka mea nui o ka ʻaila pāma a loaʻa pū kekahi i loko o ka ʻiʻo, nā huahana waiu a me kekahi mau aila meaʻai. Loaʻa ka Palmitic acid i loko o ka pauka a loaʻa kahi ākea o nā noi i nā ʻoihana like ʻole.
Hoʻohana pinepine ʻia ka pauka Palmitic acid i nā ʻoihana hoʻonaninani a me nā ʻoihana mālama pilikino. Ua ʻike ʻia no kāna mau mea emollient, e kōkua i ka palupalu a me ka hoʻomaʻamaʻa ʻana i ka ʻili. Hoʻohana maʻamau ia i ka hoʻokumu ʻana i nā creams, lotions, a me nā moisturizers. Hoʻohana ʻia ka pauka Palmitic acid i nā huahana mālama lauoho e kōkua i ke kūlana a hānai i ka lauoho.
Hiki ke hoʻohana ʻia ka waika Palmitic i kēia mau kahua:
Mea hoʻokuʻu
Hoʻohana ʻia ka Palmitic acid e hana aikopa,nā mea hoʻonaninani, a me ka poni hanamea hoʻokuʻu. Hoʻohana kēia mau noi i ka sodium palmitate, i loaʻa pinepine ʻia esaponificationo ka aila pama. No kēia hopena, ʻaila pāma, i hāʻawi ʻia mai nā lāʻau pāma (speciesElaeis guineensis), mālama ʻia mesodium hydroxide(ma ke ʻano o ka soda caustic a i ʻole lye), ʻo ia ke kumuhydrolysiso kaesterpūʻulu, hāʻawiglycerola me ka sodium palmitate.
Nā meaʻai
No ka mea he maʻalahi a hoʻohui i ke ʻano a me ka "waha” i nā meaʻai i hana ʻia (meaʻai ʻoluʻolu), ʻo ka palmitic acid a me kona paʻakai sodium ka hoʻohana nui ʻia i nā meaʻai. ʻAe ʻia ka sodium palmitate ma ke ʻano he mea hoʻohui maoli i lokomea olaolahuahana.
lāʻau lapaʻau
Hoʻohana ʻia ka pauka Palmitic acid ma ke ʻano he excipient i nā ʻano lāʻau lapaʻau a me nā mea hoʻohui. Hoʻohana pinepine ʻia e like me ka lubricant i ka hana ʻana i nā papa a me nā capsules. Hiki ke hoʻohana ʻia ka pauka Palmitic acid ma ke ʻano he mea lawe no ka lāʻau lapaʻau ikaika, e kōkua ana i ka hoʻomaikaʻi ʻana i ko lākou kūpaʻa a me ka bioavailability.
Mahiai
Hoʻohana ʻia ka pauka Palmitic acid ma ke ʻano he mea hoʻohui i ka hānai holoholona. Hoʻohui pinepine ʻia i ka hānai holoholona no ka hoʻomaikaʻi ʻana i ka meaʻai a me ka palatability. Hiki ke hoʻohana ʻia ka pauka Palmitic acid ma ke ʻano he uhi no nā mea hoʻokomo mahiʻai, e kōkua ana i ka hoʻomaikaʻi ʻana i kā lākou hoʻopuehu a me ka pono.
Koa
Aluminumnā paʻakaio ka waika palmitic a meʻakika naphthenicʻo ia nānā mea hana gellinghoʻohana ʻia me nā petrochemical volatile i ka wāKaua Honua IIe hoohua mainapalm. Loaʻa ka huaʻōlelo "napalm" mai nā huaʻōlelo naphthenic acid a me palmitic acid.
ʻO ka holoʻokoʻa, ʻo ka pauka palmitic acid ka nui o nā noi ma waena o nā ʻoihana like ʻole, e lilo ia i mea maʻalahi a waiwai. ʻO kāna mau waiwai emollient, kūpaʻa a me ka versatility e lilo ia i koho kaulana i waena o nā mea hoʻokumu a me nā mea hana e ʻimi nei e hoʻomaikaʻi i ka maikaʻi o ka huahana a me ka hana.
