笔记 Notes:
一种必需的芳香族氨基酸,是黑素的前体;多巴胺去甲肾上腺素(去甲肾上腺素) an essential aromatic amino acid that is a precursor of melanin; dopamine; noradrenalin (norepinephrine), 和甲状腺素。在许多食物中发现。用于可可替代品。调味成分;膳食补充剂 and thyroxine. Found in many foods. Used in cocoa substitutes. Flavouring ingredient; dietary supplement l-苯丙氨酸也可以转化为l-酪氨酸 L-phenylalanine can also be converted into L-tyrosine, 另一种dna编码的氨基酸。左旋酪氨酸又转化为左旋多巴 another one of the DNA-encoded amino acids. L-tyrosine in turn is converted into L-DOPA, 进一步转化为多巴胺 which is further converted into dopamine, 去甲肾上腺素(去甲肾上腺素) norepinephrine (noradrenaline), 和肾上腺素(肾上腺素)。后三种称为儿茶酚胺。苯丙氨酸(缩写为phe或f)是一种α-氨基酸,分子式为ho2cch(nh2)ch2c6h5 and epinephrine (adrenaline). The latter three are known as the catecholamines.; Phenylalanine (abbreviated as Phe or F) is an ?-amino acid with the formula HO2CCH(NH2)CH2C6H5, 具有热带果味的身体和独特的多汁荔枝甜味。其次是充满活力的绿叶紫罗兰色调,散发着精致的薄荷和水味的黄瓜味。埃及天竺葵精油是通过溶剂萃取空中植物的部分生产的 which is found naturally in the breast milk of mammals and manufactured for food and drink products and are also sold as nutritional supplements for their reputed analgesic and antidepressant effects. Phenylalanine is structurally closely related to dopamine, 肾上腺素(肾上腺素)和酪氨酸。它是橙花调节剂苯乙胺的直接前体 epinephrine (adrenaline) and tyrosine. It is a direct precursor to the neuromodulator phenylethylamine, 常用的膳食补充剂。苯丙氨酸是必需氨基酸,也是氨基酸酪氨酸前体。像酪氨酸 a commonly used dietary supplement.; Phenylalanine is an essential amino acid and the precursor for the amino acid tyrosine. Like tyrosine, 它是体内儿茶酚胺的前体(酪胺 it is the precursor of catecholamines in the body (tyramine, 多巴胺 dopamine, 肾上腺素和去甲肾上腺素)。精神药物(马斯卡林 epinephrine and norepinephrine). The psychotropic drugs (mescaline, 吗啡 morphine, 可待因 codeine, 和罂粟碱)也含有苯丙氨酸。苯丙氨酸是称为儿茶酚胺的橙花递质的前体 and papaverine) also have phenylalanine as a constituent. Phenylalanine is a precursor of the neurotransmitters called catecholamines, 是肾上腺素样物质。苯丙氨酸高度集中在 的大脑和血浆中。苯丙氨酸正常代谢需要生物蝶呤 which are adrenalin-like substances. Phenylalanine is highly concentrated in the human brain and plasma. Normal metabolism of phenylalanine requires biopterin, 铁 iron, 烟酸 niacin, 维生素b6 vitamin B6, 铜和维生素c。一般成年 每天摄取5克苯丙氨酸,最理想的情况是每天需要摄取8克苯丙氨酸。苯丙氨酸高度集中在高蛋白食品中 copper and vitamin C. An average adult ingests 5 g of phenylalanine per day and may optimally need up to 8 g daily. Phenylalanine is highly concentrated in high protein foods, 如肉 such as meat, fda 173部分-供 类食用的食品中允许的次要直接食品添加剂d部分-特定用途的添加剂sec。 173.310锅炉水添加剂.fda第173部分-供 类食用的食品中允许的次要直接食品添加剂d部分-特定用途的添加剂173.340消泡剂.fda 175部分-间接食品添加剂 cottage cheese and wheat germ. A new dietary source of phenylalanine is artificial sweeteners containing aspartame. Aspartame appears to be nutritious except in hot beverages; This essential amino acid is classified as nonpolar because of the hydrophobic nature of the benzyl side chain. The codons for L-phenylalanine are UUU and UUC. It is a white, 粉状固体。 l-苯丙氨酸(lpa)是电中性氨基酸 powdery solid. L-Phenylalanine (LPA) is an electrically-neutral amino acid, 用于生化形成蛋白质的二十种常见氨基酸之一 one of the twenty common amino acids used to biochemically form proteins, 由dna编码。被大脑用来产生去甲肾上腺素 coded for by DNA.; Used by the brain to produce Norepinephrine, 在橙花细胞和大脑之间传递信号的化学物质;然而 a chemical that transmits signals between nerve cells and the brain; however, 苯丙酮尿症患者和孕妇应避免服用。苯酮尿酸 it should be avoided by phenylketonurics and pregnant women. Phenylketonurics, 苯丙氨酸代谢有遗传错误的 who have a genetic error of phenylalanine metabolism, 血浆苯丙氨酸水平升高,高达正常水平的400倍。轻度苯丙酮尿症可能是多动症的意外原因 have elevated serum plasma levels of phenylalanine up to 400 times normal. Mild phenylketonuria can be an unsuspected cause of hyperactivity, 学习问题 learning problems, and other 发展的 发展 developmental 问题 problems in 孩子们 children. Phenylalanine can be an 有效 影响 effective 痛 pain 减压器 reliever. its it Its use in 经前 pre月经 menstrual 综合症 syndrome and Parkinson's may 提高 enhance the 效果 影响 effects of 针刺 acupuncture and 电动 electric 经皮的 transcutaneous 橙花 nerve 刺激 stimulation (十 TENS). Phenylalanine and tyrosine, 像左旋多巴 like L-dopa, 通过在大肠杆菌中发酵产生的。大肠杆菌。起始基因是 类基因的合成拷贝,其编码就这样或适于生产宿主的protachykinin-1。它最多包含19个氨基酸,其中可能包含二硫键和/或糖基化。该蛋白质由20个标准氨基酸正确序列组成 produce a catecholamine effect. Phenylalanine is better absorbed than tyrosine and may cause fewer headaches. Low phenylalanine diets have been prescribed for certain cancers with mixed results. Some tumors use more phenylalanine (particularly melatonin-producing tumors called melanoma). One strategy is to exclude this amino acid from the diet, 即 i.e., a 苯丙酮尿症 Phenylketonuria (pku PKU) diet (合规 compliance is a 难 difficult 问题 issue; it is 硬 hard to 量化 quantify and is 研究不足 under-研究 researched). The other 战略 strategy is 只是 just to 增加 increase phenylalanine's 竞争 competing amino acids, 即 i.e., 色氨酸 tryptophan, 缬氨酸 valine, 异亮氨酸和亮氨酸 isoleucine and leucine, 但不是酪氨酸。 (http but not tyrosine.
