sulfation

Worenine (Worenin) 是一种从黄连中提取的物质。它在大鼠体内第一阶段代谢中显示出脱氢，氢化，羟基化和脱亚甲基反应。在大鼠体内 II 期代谢中显示为硫酸化和葡萄糖醛酸化反应。

Sulfatides are endogenous sulfoglycolipids with various biological activities in the central and peripheral nervous systems, pancreas, and immune system. They are produced from the combination of ceramide and UDP-galactose in the endoplasmic reticulum followed by sulfation in the Golgi apparatus. The ceramide portion contains variable fatty acid chain lengths, which are tissue- and pathology-dependent. Sulfatides are primarily found in the myelin sheath of oligodendrocytes and Schwann cells, with smaller chain lengths predominant during development and longer chain lengths predominant in mature cells. They accumulate in the lysosome of patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency. Sulfatides are also located in pancreatic β-cells and inhibit insulin release from isolated rat pancreatic islet cells, suggesting a potential role in diabetes. Sulfatides can induce inflammation in glia in vitro and certain sulfatides, such as C24:1 3'-sulfo-galactosylceramide, can induce an immune response in vitro in mouse splenocytes. Sulfatides (bovine) (sodium salt) is a mixture of isolated bovine sulfatides.

p-Cresol (Standard) 是 p-Cresol 的标准品，适用于定量分析、质量控制及生化实验等相关研究。p-Cresol 是一种部分亲脂性部分，在正常条件下与血浆蛋白（接近 100%）强烈结合。对甲酚通过结合代谢，主要是硫酸化和葡萄糖醛酸化，但未结合的对甲酚至少部分通过尿液去除。
