4-Methylumbelliferyl oleate 是酸性和碱性脂肪酶 (lipases) 的荧光底物。4-Methylumbelliferyl oleate 可被脂肪酶裂解，释放出 4-Methylumbelliferyl (Ex/Em=320/450 nm)。

BDC2.5 mimotope 1040-51 is a mimotope peptide for diabetogenic T cell clone BDC2.5. isolated from non-obese diabetic mice.This is a effectively agonistic peptide (mimotope) for diabetogenic T cell clone BDC2.5. from non-obese diabetic (NOD) mice. T cells from prediabetic and diabetic NODs respond to BDC2.5 mimotope peptides.

异戊酰甘氨酸 (IVG) 是一种酰基甘氨酸。酰基甘氨酸通常是脂肪酸的次要代谢物。然而，某些酰基甘氨酸的排泄在一些先天性代谢缺陷中会增加。在某些情况下，体液中这些代谢物的测量可用于诊断与线粒体脂肪酸β-氧化相关的疾病。
