L-Tyrosine CAS 60-18-4
ʻO ka L-tyrosine he aniani keʻokeʻo a i ʻole ka pauka crystalline, ʻaʻohe ʻala a ʻawaʻawa hoʻi. Hoʻoheheʻe ia ma 334 ℃ a hiki ʻole ke hoʻoheheʻe ʻia i ka wai (0.04%, 25 ℃). ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka ethanol anhydrous, etera, a me ka acetone, akā hiki ke hoʻoheheʻe ʻia i loko o ka waikawa dilute a i ʻole ka base. ʻIsoelectric kiko 5.66.

Ke noiʻi biochemical o L-tyrosine. ʻO ka maʻamau no ka hoʻoholo ʻana i ka nitrogen i nā waikawa amino. E hoʻomākaukau i ka moʻomeheu kikokikona. E hana i ka ʻimi ʻana i ka nui o ka kala me ka hoʻohana ʻana i ka pane ʻo Milon (protein colorimetric reaction). ʻO ia ka mea kumu nui no ka synthesizing i nā hormones peptide like ʻole, nā lāʻau lapaʻau, a me nā lāʻau lapaʻau ʻē aʻe, nā waikawa amino precursors o dopamine a me catecholamines.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
