Hoʻolauna

ʻO D-alanine kahi amino amino kiral. ʻO D-alanine he paʻa kalakala kala ʻole i hiki ke hoʻoheheʻe ʻia i ka wai a me nā ʻakika. He ʻakika a me ka alkaline a hana pū nō hoʻi ma ke ʻano he waikawa organik.

 

He maʻalahi ke ʻano o ka hoʻomākaukau ʻana o D-alanine. Loaʻa kahi ʻano hoʻomākaukau maʻamau e ka enzymatic catalysis o nā hopena chiral. Hiki ke loaʻa iā D-alanine ma o ka hoʻokaʻawale chiral o alanine.

He mea hoʻopilikia maʻamau e hoʻonāukiuki i ka maka, ka ʻōpū hanu, a me ka ʻili. Pono e hoʻohana ʻia nā aniani palekana kemikala, nā mīkina lima a me nā maka i ka wā o ka hana e hōʻoia i ka palekana.

 

Eia kahi hoʻolauna pōkole i nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o D-alanine. No ka ʻike kikoʻī hou aku, e ʻimi i ka palapala kemika kūpono a i ʻole e nīnau i kahi loea.
