One theory is that it's an autoimmune reaction attacking the body's glutamic acid decarboxylase (GAD) protein.

一种理论认为这是一种攻击人体谷氨酸脱羧酶（GAD）蛋白的自身免疫反应。

And, if the glutamic acid residues of gla-containing proteins are not carboxylated, calcium cannot be properly bound.

如果含谷氨酸残基蛋白没有羧化，钙就不定。

Almost always, the sickle cell mutation is a non-conservative missense mutation that results in the sixth amino acid of beta-globin being valine instead of glutamic acid.

状细胞突变几乎总是由于非保守区错义突变，导致β-珠蛋白的第6个氨基酸为缬氨酸，而非谷氨酸。

And MSG is closely related to glutamic acid, an amino acid that acts as a neurotransmitter in lots of animals, including humans.

味精与谷氨酸密切相关，谷氨酸是一种氨基酸， 在包括人类在内的许多动物中充当神经递质。

Aldolase A is made of 350 amino acids, the building blocks of proteins, but the bit that does the work consists of only three of these: lysine, glutamic acid and tyrosine. The rest of the enzyme is packaging.

醛缩酶A由350种氨基酸组成，这些氨基酸是蛋白质的组成成分，但起作用的部分只有三个：赖氨酸、谷氨酸和酪氨酸。剩下的酶是包装的。
