核心 1 聚糖

核心1聚糖是自然界中最常见的O-连接聚糖。它是抗原性的，也称为T抗原。它形成其他O-连接聚糖的核心结构，通常含有唾液酸，从末端β-连接半乳糖或丝氨酸/砌氨酸连接的GlcNAc延伸而来。较大的O-连接聚糖的延伸还包括半乳糖、GlcNAc、GalNAc或岩藻糖。

The core 1 glycan is the most common O-linked glycan found in nature. It is antigenic, also known as the T antigen. It forms the core structure of other O-linked glycans, most often containing sialic acids, extended from the terminal beta-linked galactose or the serine/thronine-linked GlcNAc. Extension of larger O-linked glycans also includes galactose, GlcNAc, GalNAc, or fucose.
