Now, to prevent the hydrochloric acid from the stomach from damaging the intestinal mucosa, enteroendocrine cells also secrete another hormone, called secretin, which stimulates the pancreatic duct cells to secrete water and bicarbonate.

为了避免胃部产生的胃酸对小肠粘膜造成损伤，小肠内分泌细胞还可分泌胰泌素；它可以刺激胰腺导管细胞分泌水和碳酸氢盐。

It's a quick bread that's made, it's leavened with sodium bicarbonate.

This can cause symptoms like vomiting and voluminous amounts of watery diarrhea containing extremely high concentrations of sodium, potassium, chloride, bicarbonate; as well as high levels of live V. cholerae ready to infect another individual.

这可能导致呕吐、含有大量高浓度的钠、钾、氯化物和碳酸氢盐的水样腹泻，以及可能感染另一个人的高活跃性的霍乱弧。

The significance of this is that, at ejaculation, a tiny pellet of sperm is pushed forward and mixed with seminal fluid, suddenly quintupling the bicarbonate concentration.

这种情况因为，射精时一小团精子与精混合，碳酸氢盐浓度瞬间提高五倍。

Club soda is just water with a few add-ins: carbon dioxide for carbonation and “mineral-like” ingredients such as sodium bicarbonate, sodium citrate, and potassium sulfate.

club soda 加了一些加剂的水：用于碳酸化的二氧化碳和“类似矿物”的成分，如碳酸氢钠、柠檬酸钠和硫酸钾。

Meanwhile, ion exchangers on the basal surface of the cell move the negatively charged bicarbonate ion into the extracellular space, causing an increase in pH.

同时，细胞基底面的离子交换将带负电荷的碳酸氢根离子移入细胞外，导致pH值升高。

Lastly the gastric mucosa is highly vascularized, which helps deliver oxygen and bicarbonate and carry away acid that makes it through into the lamina propria.

最后，胃粘膜高度血管化，这有助于输送氧气和碳酸氢盐并带走酸，使其通过固有层。

Overall, in terms of fitness, sodium bicarbonate supplementation has some small benefit, particularly in endurance or metabolic activities, but more research is still needed.

总的来说，在健康方面，碳酸氢钠的补充有一些小的好处，特别在耐力或代谢活动，但仍需要更多的研究。

That carbon dioxide can diffuse into a cell and react with water to form carbonic acid which quickly breaks into a proton and bicarbonate.

二氧化碳可以扩散到细胞中，与水反应形成碳酸，它会迅速分解成H+和HCO3-。

But they're really just positively-charged cations — like calcium, sodium, and potassium — and negatively-charged anions, like phosphate, sulfate, and bicarbonate.

但它们实际上带正电荷的阳离子——比如钙、钠和钾——和带负电荷的阴离子，比如磷酸盐、硫酸盐和碳酸氢盐。

It is a source of a messenger molecule called cAMP, and its activity is regulated by bicarbonate ions.

它一种名为cAMP的信使分子的来源，其活动受到碳酸氢根离子的调节。

In the case of health, sodium bicarbonate indeed has a solid track record largely thanks to its metabolic acidosis buffering, aiding the kidneys in acid-base balance and preventing bone mineral loss.

在健康方面， 有记录显示碳酸氢钠确实有助于健康，这在很大程度上归功于它的代谢性酸中毒的缓冲作用，帮助肾脏酸碱平衡，防止骨矿物质流失。

It's also where stuff like bicarbonate from the pancreas gets dumped, to help neutralize the stomach acid before it burns a hole in your guts.

这也胰腺中碳酸氢盐等物质被倾倒的地方，以帮助在胃酸在你的肠道烧开一个洞之前中和胃酸。

A generous amount of bicarbonate is also secreted by a number of glands lying in the submucosa of the duodenal wall.

十二指肠肠壁上分布的大量腺体，也可分泌大量的碳酸氢盐。

TDI-11861 blocks the places on sAC where bicarbonate would normally bind, rendering it unresponsive to this rapid change in concentration.

TDI-11861阻断了sAC上碳酸氢盐正常结合的点位，不让其对浓度的快速变化产生反应。

Saliva contains bicarbonate ions, which helps to neutralize acid in the mouth, and glycoproteins like mucin which thickens the saliva.

它包含着碳酸氢根离子，可以中和口腔中的酸，还有糖蛋白，可以使唾变得粘稠。

Weak bases, like sodium bicarbonate (baking soda), consume much less, and generally have pHs in the 8-11 range.

水中性的，所以7就在pH标度的中间。

Like low levels of bicarbonate can cause metabolic acidosis with deep and labored breathing called Kussmaul breathing.

低水平的碳酸氢盐会导致代谢性酸中毒，伴随深大呼吸，称为Kussmaul呼吸。

The bicarbonate goes back into the blood in exchange for a chloride ion, leaving behind a proton.

HCO3-回到血中交换CL-，留下一个H+。

So, the abnormally high levels of luminal sodium and chloride disrupt the osmotic balance between the intestines and surrounding tissue; and water, bicarbonate, and potassium rush into the lumen of the intestines as a result.

因此，异常高水平的管腔钠和氯破坏了肠道和周围组织之间的渗透平衡；水、碳酸氢盐和钾因而涌进肠腔。
