单词 Phosphate ion
释义

Phosphate ion

原声例句
Crash Course 综合篇

Phosphate ion has a three charge, so it bonds with three hydrogen ions to form phosphoric acid.

磷酸根离子带有三个电荷, 因此它与三个氢离子结合形成磷酸。

Osmosis-泌尿

If calcium levels fall, the four parathyroid glands buried within the thyroid gland release parathyroid hormone which frees up both calcium and phosphate ions from the bones.

如果钙水平下降,那么在甲状腺内的四个甲状旁腺释放甲状旁腺激素,导致骨骼中释放钙和磷酸盐离子。

Osmosis-泌尿

Another possibility is not absorbing enough through the gastrointestinal tract, because usually phosphate ions are absorbed in the GI tract, but some substances like alcohol or a medication can impair that phosphate absorption, which means it gets excreted.

另一种可能是胃肠道吸收不足,因为磷酸盐离子通常会被消化道吸收,但有些物质,如酒精或药物,会损害磷酸盐的吸收,也就意味着磷酸盐会被排出体外。

磷酸盐 Phosphate

(重定向自Phosphate ion)
这是磷酸氢(HPO42−)分子的模型。中间橙色的是磷原子,红色的是氧原子,而白色的是氢原子。
在酸性溶液下磷酸官能团的结构式。在碱性的溶液下,该官能团会释放两个氢原子,并离化磷酸盐带有-2的形式电荷[1]。
磷酸石样本
每年平均海水表面的磷酸盐浓度[2]

磷酸盐phosphate(PO4)),是磷酸的盐,在无机化学、生物化学及生物地质化学上是很重要的物质。

磷酸盐离子是一个多原子的离子,其实验式是PO4,而分子量是94.97。它包含一个磷原子,并由四个氧原子所包围,形成一个正四面体。磷酸盐离子带有-3的形式电荷,且是磷酸氢盐离子(HPO4)的共轭碱;磷酸氢盐离子则是磷酸二氢盐离子(H2PO4)的共轭碱;而磷酸二氢盐离子又是磷酸(H3PO4)的共轭碱。它是一个超价分子(磷原子在其价壳层有着10个电子)。如果磷酸盐作为一种有机磷化合物就被称为磷酸酯,其化学式为OP(OR)3

英语百科

Phosphate 磷酸盐

(重定向自Phosphate ion)
This is the structural formula of the phosphoric acid functional group as found in  weakly acidic aqueous solution. In more basic aqueous solutions, the group donates the two hydrogen atoms and ionizes as a phosphate group with a negative charge of 2.
[3]

A phosphate (PO3−
4
) is an inorganic chemical and a salt of phosphoric acid. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Of the various phosphoric acids and phosphates, organic phosphates are important in biochemistry and biogeochemistry (ecology), and inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry. At elevated temperatures in the solid state, phosphates can condense to form pyrophosphates.
