설명

애플리케이션

• Digestibility and Microbiota Modulation by Dietary Sialic Acid: Research indicated that sialylation of dietary mucin can modulate its digestibility and subsequently affect the gut microbiota of elderly individuals, highlighting the significance of N-Acetylneuraminic acid in dietary formulations and gut health (Fang et al., 2024).

생화학적/생리학적 작용

Both sialic acid and neuraminic acid are loosely used to refer to conjugates of neuraminic acid. N-Acetylneuraminic acid is often found as the terminal sugar of cell surface glycoproteins. Cell surface glycoproteins have important roles in cell recognition and interaction as well as in cell adhesion. Membrane glycoproteins are also important in tumor growth and metastases.
