| DL-トリプトファン Usage And Synthesis |
外観 | 白色~わずかにうすい褐色, 結晶性粉末~粉末 | 定義 | 本品は、次の化学式で表されるアミノ酸である。 | 溶解性 | 水にやや溶けにくく、うすい酸及び水酸化ナトリウム溶液に溶ける。 | 用途 | アミノ酸研究用。 | 化粧品の成分用途 | ヘアコンディショニング剤、皮膚コンディショニング剤 | 化学的特性 | White crystals. Slightly soluble in
water; stable in alkaline solution; decomposed by
strong acids. | 使用 | DL-Tryptophan is an amino acid precursor of serotonin and melatonin. It is a dietary supplement for use as an antidepressant, anxiolytic, and sleep aid. DL-tryptophan also can be used as feed nutrition enhancer, antioxidants. | 定義 | ChEBI: An alpha-amino acid that is alanine bearing an indol-3-yl substituent at position 3. | 一般的な説明 | Tryptophan is the precursor for 5-hydroxy-tryptamin and an essential α-amino acid. DL-Tryptophan exists as a zwitterion during crystallization. | Biochem/physiol Actions | DL-Tryptophan binding to bovine serum albumin is employed for its affinity based chromatographic purification. Supplementation of tryptophan in diets of rat induce bladder tumor. | 安全性プロファイル | Experimental
reproductive effects. Questionable
carcinogen with experimental carcinogenic
data. When heated to decomposition it
emits toxic fumes of NOx. |
