Beta hydroxybutyric acid on the other hand, even though it's still one of the ketone bodies, isn't technically a ketoacid since its ketone group has been reduced to a hydroxyl group.
而β-羟基丁酸虽说也是酮体，但却不是酮酸，因为它的酮基团被还原成了羟基。
Ketoacid

Osmosis-内分泌

Individuals will also have a high anion gap, which reflects a large difference in the unmeasured negative and positive ions in the serum, largely due to this build up of ketoacids.
患者也会有阴离子间隙偏高，指的是血浆中未测定的阴阳离子浓度差值高，主要原因是酮酸的积累。
Osmosis-泌尿
Similarly, when there's a metabolic acidosis from excess organic acids like lactic acid and ketoacids, protons can enter cells with the organic anion rather than having to get exchanged for potassium ions.
相同地，当有机酸如乳酸和酮酸过多，产生代谢性酸中毒时，质子会和有机阴离子一起进入细胞，而不是同钾离子交换。
Osmosis-内分泌
After that happens, the liver turns the fatty acids into ketone bodies, like acetoacetic acid and beta hydroxybutyric acid; acetoacetic acid is a ketoacid because it has a ketone group and a carboxylic acid group.
此后，肝把脂肪酸转化成酮体，比如乙酰乙酸、β-羟基丁酸；乙酰乙酸是一种酮酸，因为它有酮基团和羧酸基团。

酮酸 Keto acid
（重定向自Ketoacid）
酮酸（英语：Keto acid）是一类在生物体内拥有重要作用的有机酸，在氨基酸新陈代谢和维持氧化还原状态的过程中它起一个中心作用。酮酸分两种：
- α-酮酸含有氨基酸的碳结构骨架。
- β-酮酸是高能量的（不稳定的）代谢物，它可以失去羧基同时释放能量促进其它反应进行（脱羧）。

Keto acids or ketoacids (also called oxo acids or oxoacids) are organic compounds that contain a carboxylic acid group and a ketone group. In several cases, the keto group is hydrated. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in glycolysis.
