笔记 Notes: 调味成分 Flavouring ingredient, 膳食补充剂 dietary supplement, 养分 nutrient
支链氨基酸（bcaa）是必需氨基酸，其碳结构以分支点为标志。这三种氨基酸对 类生活至关重要，尤其与压力有关 Branched chain amino acids (BCAA) are essential amino acids whose carbon structure is marked by a branch point. These three amino acids are critical to human life and are particularly involved in stress, 能量和肌肉代谢。 bcaa补充疗法 energy and muscle metabolism. BCAA supplementation as therapy, 口服和静脉注射 both oral and intravenous, in 的 human 健康 health and 疾病 disease 持有 holds 大 great 诺言 promise. "bcaa BCAA" 表示 denotes 缬氨酸 valine, 异亮氨酸和亮氨酸是支链必需氨基酸。尽管它们在结构上相似 isoleucine and leucine which are branched chain essential amino acids. Despite their structural similarities, 支链氨基酸具有不同的代谢途径 the branched amino acids have different metabolic routes, 缬氨酸仅用于碳水化合物 with valine going solely to carbohydrates, 亮氨酸仅对脂肪和异亮氨酸两种。不同的新陈代谢导致 体对这些必需氨基酸需求不同 leucine solely to fats and isoleucine to both. The different metabolism accounts for different requirements for these essential amino acids in humans: 12毫克/千克 12 mg/kg, 14 mg / kg kg和16 mg / kg kg缬氨酸 , 亮氨酸和异亮氨酸分别。此外 leucine and isoleucine respectively. Furthermore, 这些氨基酸有不同的缺乏症状。缬氨酸缺乏症的特征是大脑橙花功能缺损 these amino acids have different deficiency symptoms. Valine deficiency is marked by neurological defects in the brain, 而异亮氨酸缺乏症则以肌肉震颤为特征。肝病患者的bcaa减少 while isoleucine deficiency is marked by muscle tremors. BCAA are decreased in patients with liver disease, 如肝炎 such as hepatitis, 肝昏迷 hepatic coma, 肝硬化 cirrhosis, 肝外胆道闭锁或门腔分流;芳香族氨基酸（aaa）-酪氨酸 extrahepatic biliary atresia or portacaval shunt; aromatic amino acids (AAA)-tyrosine, 色氨酸和苯丙氨酸 tryptophan and phenylalanine, 以及蛋氨酸在这些情况下都增加了。缬氨酸 as well as methionine-are increased in these conditions. Valine, 特别是 in particular, 已经建立了对生病的肝有用的补充疗法。所有的bcaa都可能与aaa竞争进入大脑的吸收。补充维生素B6和锌的bcaa有助于使bcaa正常化 has been established as a useful supplemental therapy to the ailing liver. All the BCAA probably compete with AAA for absorption into the brain. Supplemental BCAA with vitamin B6 and zinc help normalize the BCAA:氨基酸比率。 bcaa并非没有副作用。单独亮氨酸 AAA ratio. The BCAA are not without side effects. Leucine alone, 例如 for example, 4-（对羟基苯基）-4-（3-氧代丁基）苯酚4-（3-氧代丁基）苯酚氟壬壬-氢苄基丙酮对氢苄基丙酮4羟基苯基-2-丁酮4-羟基-4-苯基丁烷-2-one4-（4-羟基-苯基）-丁烷-2-酮-羟基苄基丙酮对羟基苄基丙酮（对羟基苄基）丙酮4-羟基苄基丙酮对羟基苄基丙酮1-对羟基苯基-3-丁酮1-对羟基苯基-3-丁酮4-（4-羟基苯基）丁烷- 2-one4-（4-羟基苯基）-2-丁酮4-（对羟基苯基）-2-丁酮4-（对羟基苯基）-2-丁酮4-（4-羟基苯基）-2-丁酮天然1-（4-羟基苯基） -3-丁酮1-（对羟基苯基）-3-丁酮1-（对羟基苯基）-3-丁酮4-（对羟基苯基）2-丁酮4-（4-羟基苯基）丁-2-酮4-（对羟基苯基）丁酮-2-酮2-（4-羟苯基）乙基甲基酮羟苯基丁酮 exacerbates pellagra and can cause psychosis in pellagra patients by increasing excretion of niacin in the urine. Leucine may lower brain serotonin and dopamine. A dose of 3 g of isoleucine added to the niacin regime has cleared leucine-aggravated psychosis in schizophrenic patients. Isoleucine may have potential as an antipsychotic treatment. Leucine is more highly concentrated in foods than other amino acids. A cup of milk contains 800 mg of leucine and only 500 mg of isoleucine and valine. A cup of wheat germ has about 1.6 g of leucine and 1 g of isoleucine and valine. The ratio evens out in eggs and cheese. One egg and an ounce of most cheeses each contain about 400 mg of leucine and 400 mg of valine and isoleucine. The ratio of leucine to other BCAA is greatest in pork, 其中亮氨酸为7至8克，而其他bcaa在一起仅为3至4克。 （http where leucine is 7 to 8 g and the other BCAA together are only 3 to 4 g. (http: //www.营养不良 dcnutrition.com）
