半乳糖脑苷脂（galactocerebroside、galactosylceramide）是一种包含由"部分1-羟基"(1-hydroxyl moiety)半乳糖残基之神经酰胺(Ceramide)所组成的脑苷脂。

半乳糖是由半乳糖基神经酰胺酶(Galactosylceramidase)所裂解。

半乳糖脑苷脂是脑里之少突神经胶质细胞(oligodendrocyte)的标记物，且无论它们是否形成髓磷脂。

A galactocerebroside (or galactosylceramide) is a type of cerebroside consisting of a ceramide with a galactose residue at the 1-hydroxyl moiety.

The galactose is cleaved by galactosylceramidase.

Galactocerebroside is a marker for oligodendrocytes in the brain, whether or not they form myelin.
