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

去年夏天，他们证明了，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，小麦有一种化酶，能够分解。

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小麦中能够编码化酶的基因转移到了栗树的基因中。

Like many plants, tea leaves contain tiny, hard crystals called phytoliths made of calcium oxalate.

像许多植物一样，茶叶含有微小的体，称为植硅体，由钙制成。

The most common type of stones are calcium oxalate stones, though other types include uric acid stones and struvite stones.

钙结石是最常见的类型，其他类型的结石有尿结石和感染性结石。

Urine contains compounds that consist of calcium, sodium, potassium, oxalate, uric acid, and phosphate.

尿液中含有由钙、钠、钾、盐、尿和磷盐组成的化物。

Foods like potato chips, spinach, rhubarb, and beets are high in oxalate, so doctors might advise limiting them.

薯片、菠菜、大黄和甜菜等食物的盐含量很高，因此医生可能会建议限制摄入。

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

钙结易形成于性尿中，而磷钙结易形成于碱性尿中。

Calcium oxalate is the most common type of crystal to form this way, and accounts for about 80% of kidney stones.

钙是最常见的以这种方式形成的体类型，约占肾结石的 80%。

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基团结而非，形成的磷钙结石呈灰白色，也在x线片上显影。

For people prone to them, their doctor may recommend drinking plenty of water, which dilutes the calcium oxalate and other compounds that eventually build up into painful stones.

对于易患结石的人，他们的医生可能会建议多喝水，这会稀释钙和其他最终形成疼痛性结石的化物。

Even though calcium is often found in stones, calcium in foods and beverages can actually help by binding to oxalate in the digestive tract before it can be absorbed and reach the kidneys.

尽管钙通常存在于结石中，但食物和饮料中的钙实际上可以通过与消化道中的盐结，然后在盐被吸收并到达肾脏之前起到帮助作用。

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.

另一小组是结钙，带正电的钙离子共价结至微小的带负电的离子上，例如盐离子；盐是体积较小的阴离子，通常少量存在于血液中。
