This extra oxalate can then crystallize in the bladder and cause kidney stones.

这份额外的草酸会在膀胱中结晶并导致肾结石。

Last summer they showed that oxalate oxidase can indeed enhance blight-resistance.

去年夏天，他们证明了，草酸氧化酶的确能够增强栗树的抗枯萎性。

He also knew that wheat has an enzyme called oxalate oxidase, which detoxifies oxalic acid.

他也清楚，有草酸氧化酶，能够分解草酸。

He and his team therefore transferred the gene that encodes oxalate oxidase from wheat to chestnut.

于是，鲍威尔和他的团队将中能够编码草酸氧化酶的基因转移到了栗树的基因中。

Calcium oxalate crystals are more likely to form in acidic urine, whereas calcium phosphate crystals are more likely to form in alkaline urine.

草酸钙结晶易形成于酸性尿中，而磷酸钙结晶易形成于碱性尿中。

The most common of these are made from calcium oxalate, and studies have found that phosphoric acid changes urine composition and causes a rise in oxalate.

其中最常见的是草酸钙，研究发现磷酸会改变尿液成分，导致草酸含量上升。

Sometimes, instead of oxalate, the calcium binds a negatively charged phosphate group to form calcium phosphate stones, which are dirty white in color and alsop radiopaque on an Xray.

有时候，钙离子与带负电荷的磷酸基团结合而非草酸，形成的磷酸钙结石呈灰白色，也在x线片上显影。

The other category is complexed calcium, which is where the positively charged calcium is ionically linked to tiny negatively charged molecules like oxalate, which is a small anion that are normally found in our blood in small amounts.

另组是结合钙，带正电的钙离子共价结合至微的带负电的离子上，例如草酸盐离子；草酸盐是体积较的阴离子，通常少量存在于血液中。
