Sialic acid (also known as N-acetylneuraminic acid) is a nine-carbon sugar. It is a naturally occurring carbohydrate.
Sialic acid was originally isolated from the mucin of the submandibular gland, hence the name. Sialic acid is usually present in the form of oligosaccharides, glycolipids or glycoproteins. The brain has the highest levels of sialic acid in the human body. The main food source of sialic acid is the edible bird’s nest, breast milk, also found in milk, eggs and cheese.
Sialic acid can increases brain intellectual development, improves memory and improve human immunity. It also can nourish skin and anti-aging. So it’s a good choice to use it as raw material of health care products and cosmetics.
