ʻO NIKOTINAMIDA
Hoʻolauna
ʻO Niacinamide, i ʻike ʻia hoʻi ʻo nicotinamide, ka huaora B3 a i ʻole ka huaora PP, he huaora wai-hoʻoheheʻe ʻia a no nā huaora B. ʻO ka ʻāpana niacinamide i loko o kēia mau ʻano coenzyme ʻelua i loko o ke kino o ke kanaka he mau waiwai o ka hoʻohui ʻana i ka hydrogen a me ka dehydrogenation, kahi e pāʻani ai i kahi kuleana i ka oxidation biological. Hiki i ka hoʻoili ʻana o ka hydrogen ke hoʻoulu i ka hanu ʻana o nā ʻiʻo, ke kaʻina hana oxidation biological a me ka metabolism, he mea nui ia no ka mālama ʻana i ka pono o nā ʻiʻo maʻamau, ʻoiai ka ʻili, ka ʻōnaehana digestive a me ka ʻōnaehana nerve. Ke nele, hana ia i ka prosthema no ka mea ua pilikia ka hanu ʻana a me ka metabolism o nā cell.

He kristal keʻokeʻo a i ʻole ka pauka crystalline e like me ke kui, ʻaʻohe ʻala a pilau iki paha, a ʻawaʻawa iki. ʻO ka nui o ka mānoanoa he 1.4, a ʻo ke kiko heheʻe he 129-131℃. Hiki ke hoʻoheheʻe ʻia ka 1g o kēia huahana i loko o 1mL o ka wai, 1.5mL o ka ethanol a i ʻole 10mL o ka glycerine, a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka ether. He paʻa iki ia. He kūpaʻa ia i ka waikawa, alkali a me ke kiʻekiʻe o ka mahana. He kūpaʻa ia i ka mālamalama a me ka wela i ka ea maloʻo. Ke hoʻomehana ʻia i loko o nā hopena alkaline a acidic paha, hana ia i ka niacin.
Hana kino
Ka hiki ke kū'ē i ka wrinkle maikaʻi ʻO ka hiki ke kū'ē i ka wrinkle o ka niacinamide, hiki iā ia ke hoʻoulu i ka ChemicalbookATP, hāʻawi i ka ikaika i nā keratin cell, hoʻonui i ka synthesis o collagen, a he synergy maikaʻi, hiki ke hoʻohana ʻia me nā mea anti-wrinkle ʻē aʻe. Ua hōʻike ʻia nā haʻawina he nui ma ka home a ma waho e hiki i ka niacinamide ke hōʻemi pono i ka hanana o ka immunosuppression māmā o ka ʻili ma lalo o ka irradiation ultraviolet.
