L-cysteine Base | 52-90-4
Hōʻike huahana:
ʻO ka Cysteine he aniani keʻokeʻo a i ʻole ka pauka crystalline, hiki ke hoʻoheheʻe ʻia i ka wai, ʻala iki, hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol, ʻaʻole hiki ke hoʻoheheʻe ʻia e like me ka etera. Ka helu heheʻe 240 ℃, ʻōnaehana monoclinic. ʻO Cysteine kekahi o nā waikawa amino i loaʻa i ka sulfur, ʻo ia ka waikawa amino pono ʻole.
I loko o ke kino, ua hoʻololi ʻia ka sulfur atom o methionine me ka hydroxyl oxygen atom o serine, a ua synthesized ma o cystathionine.
Mai ka cysteine, hiki ke hana ʻia ka glutathione. glycerol. ʻO ka Cysteine he paʻa paʻa, akā hiki ke hoʻoheheʻe ʻia i ka cystine i loko o nā hopena kūʻokoʻa a me ka alkaline.
ʻO ka maikaʻi o ka L-cysteine Base:
Loaʻa iā ia ka cohesion ma ke kino, etc.
E pale a mālama pono i ka ʻeha radiation.
Mālama ʻo ia i ka hana o ka sulfhydrylase koʻikoʻi i ka hana keratin o nā protein ʻili, a hoʻohui i nā pūʻulu sulfur e mālama i ka metabolism maʻamau o ka ʻili a hoʻoponopono i ka melanin lalo i hana ʻia e nā ʻāpana puaʻa i ka papa haʻahaʻa o ka epidermis. He mea hoʻomaʻemaʻe keʻokeʻo maoli maoli ia.
I kēlā me kēia manawa e loaʻa ai ka ʻāʻī a i ʻole ka maʻi allergy, hoʻemi ʻia ka sulfydrylase e like me ka cholphosphatase, a hiki i ka L-cysteine supplementation ke mālama i ka hana o ka sulfydrylase a hoʻomaikaʻi i nā hōʻailona o ka ʻili o ka mumū a me ka allergy.
Loaʻa iā ia ka hopena o ka hoʻoheheʻe ʻana i ke keratin, no laila he kūpono no nā maʻi ʻili me ka hypertrophy keratin.
Loaʻa iā ia ka hana o ka pale ʻana i ka ʻelemakule biological.
