主打产品:唾液酸 (Sialic Acid) | Core Product: Sialic Acid

产品概述 | Product Overview

唾液酸 是一类九碳单糖神经氨酸衍生物的统称,最常见的形式是N-乙酰神经氨酸。在自然界中,它是细胞膜表面糖蛋白糖脂末端的重要组成成分,尤其大量存在于大脑灰质、神经节苷脂、母乳燕窝中,被誉为“脑黄金”和“智慧营养素”。唾液酸是细胞识别、信号传导、免疫调节、大脑与神经系统发育、抗病毒与抗粘附等生命过程的关键参与者。作为高价值的营养强化剂和生物活性物质,它在婴幼儿配方食品、膳食补充剂、功能食品饮料、化妆品生物医药领域具有广阔的应用前景。

Sialic Acid is a collective term for a family of nine-carbon monosaccharide neuraminic acid derivatives, the most common form being N-Acetylneuraminic Acid. In nature, it is a crucial terminal component of glycoproteins and glycolipids on cell membranes, particularly abundant in brain grey matter, gangliosides, human breast milk, and edible bird's nest. It is hailed as "Brain Gold" and the "Nutrient of Intelligence." Sialic acid is a key player in vital biological processes such as cell recognition, signal transduction, immune regulation, brain and nervous system development, antiviral activity, and anti-adhesion. As a high-value nutritional fortifier and bioactive substance, it holds vast application prospects in infant formula, dietary supplements, functional foods and beverages, cosmetics, and the biomedical sector.
