ʻO DL pyroglutamic acid he amino acid, i ʻike ʻia ʻo DL-2-aminoglutaric acid. ʻO ka DL pyroglutamic acid he pauka crystalline kala ʻole i hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol.

ʻElua mau ala no ka hana ʻana i ka DL pyroglutamic acid: chemical synthesis a me microbial fermentation. Loaʻa ka synthesis kemika ma ka hana ʻana i nā pūhui kūpono, ʻoiai ʻo ka microbial fermentation e hoʻohana i nā microorganism kikoʻī e metabolize a synthesize i ka amino acid.

ʻIke palekana no ka DL pyroglutamic acid: Manaʻo ʻia ʻo ia he pūhui palekana me ka ʻike ʻole o nā mea ʻona. Ma ke ʻano he kemika, pono e mālama ʻia a hoʻohana ʻia ma lalo o nā kūlana kūpono, e pale aku i ka hoʻopili ʻana me nā oxidants ikaika. Ma mua o ka hoʻohana ʻana i ka DL pyroglutamic acid, pono e mālama ʻia e like me nā kaʻina hana kūpono a me nā hana pale pilikino.
