2,2-Dihydroxyacetic acid (Formylformic acid) 是乙醛酸循环的中间体，使某些生物体能够将脂肪酸转化为碳水化合物。2,2-Dihydroxyacetic acid 被发现与原发性高草酸尿有关，这是一种先天性代谢错误。作为一种醛，乙醛酸酯也具有高活性，可以修饰蛋白质形成晚期糖基化产物(AGEs)。

DL-Mandelic acid (acidomandelico) 是一种 α-羟基羧酸，有抗菌活性，广泛用作医药和精细化学品的中间体，已用于研究尿路感染和阴道滴虫病，还具有较高的精子固定活性和较低的阴道刺激性。

Erucic acid (13(Z)-Docosenoic Acid) 是单不饱和脂肪酸，分离自萝卜的种子。Erucic acid 可以容易地穿过血脑屏障，使大脑中长链脂肪酸的积累正常化。Erucic acid 能够改善认知障碍并有效预防痴呆。

Palmitoleic acid ((Z)-Hexadec-9-enoic acid) 是脂肪酸的组成部分，能够预防 SHRSP 大鼠因脑血管疾病引起的死亡。

Phenylpyruvic acid (3-Phenylpyruvic acid) 可以通过乳酸脱氢酶合成3-苯基乳酸 (PLA)。

Malonic acid (propanedioic acid) 是竞争性抑制剂的典型例子：它作用于呼吸电子传递链中的琥珀酸脱氢酶(复合物 II)。发现丙二酸与丙二酰辅酶A 脱羧酶缺乏有关，这是一种先天性代谢错误。

UMK57 是一种CENP-Ei、MCAK 增强剂，选择性促进 k-MT 附着错误纠正以抑制染色体错误分离的小分子化合物，可以通过破坏有丝分裂过程中动粒微管 (k-MT) 附着的稳定性来提高染色体分离保守性。

3-Amino-2-methylpropanoic acid (α-Methyl-β-alanine) 是 N-carbamyl-beta-aminoisobutyric acid 经 enzyme Beta-ureidopropionase (EC 3.5.1.6)转化后的产物，是嘧啶降解的最后一步。-尿嘧啶丙酸酶缺乏症是一种与神经异常相关的嘧啶降解的先天性错误。

Dihydroxyacetone phosphate (DHAP) is a crucial intermediate in lipid biosynthesis and glycolysis, participating in numerous metabolic pathways, including the Calvin cycle and glycolysis in plants.

Octanoic acid-13C is intended for use as an internal standard for the quantification of octanoic acid by GC- or LC-MS. Octanoic acid is a medium-chain saturated fatty acid. It has been found in Teleme cheeses made from goat, ovine, or bovine milk.1 Octanoic acid is active against the bacteria S. mutans, S. gordonii, F. nucleatum, and P. gingivalis (IC80s = <125, <125, 1,403, and 2,294 μM, respectively).2 Levels of octanoic acid are increased in the plasma of patients with medium-chain acyl-CoA dehydrogenase (MCAD) deficiency, an inborn error of fatty acid metabolism characterized by hypoketotic hypoglycemia, medium-chain dicarboxylic aciduria, and intolerance to fasting.3,4 |1.
