"Sialic acid 唾液酸 is N-acetylneuraminic acid, and it serces as a cap to protect proteins from receptors in the plasma membrane of liver cells that remove sialyated proteins from the bloodsteam. The half-life of sialylated proteins is substantially longer than the comparable protein without sialic acid."
