酪氨酸

The product chorismate of this pathway is precursor to the synthesis of the aromatic amino acids phenylalanine,tyrosine,and tryptophan as well as other essential aromatic secondary metabolites such as ubiquinone,menaquinone and vitamin K.

芳香族氨基酸苯丙氨酸、酪氨酸、色氨酸和其它一些必需代谢物如泛醌、维生素K2类、维生素K的起始物是莽草酸途径所产生的分枝酸。

The experimental results show that in the presence of acetic anhydride, the L-tyrosine can be completely racemized and converted into DL-tyrosine both in NaOH aqueous solution and in acetic acid solvent, and moreover, in the presence of acetic anhydride

今讨论了在碱性水溶液中，L-酪氨酸、乙酸酐和NaOH三者摩尔比例对消旋过程的影响和在纯乙酸溶剂中，乙酸用量和L-酪氨酸与乙酸酐的摩尔比例与消旋温度对消旋过程的影响。结果表明在乙酸酐的作用下，L-酪氨酸在纯乙酸溶剂中的消旋具有消旋速度快，DL-酪氨酸收率高的优点。

Compared with development stage at the fortith day, total exudation rates of amino acids and organic acids in common genotype at the fifith day decreased sharply, while it kept rather stationary in potassium-rich genotype; At three growth phrases, tyrosine, serine and y-amidobutyricacid were dominant amino acids in root exudates of those two genotypes, malic acid was dominant organic acids, and the proportision of malic acid to total exudation increased with the prolongation of growth phase prolonged.

在3个生长期内，酪氨酸、γ-氨基丁酸和丝氨酸均为两类基因型根系分泌物中的主要氨基酸种类，苹果酸则是主要的有机酸类型，其在氨基酸和有机酸分泌总量中所占相对比例均随生长期的延长而升高。3籽粒苋根系分泌物处理后的土壤速效钾含量均高于清水对照处理，富钾基因型在低钾胁迫时的根系分泌物对土壤钾的活化作用明显大于一般基因型。
