描述
Lacto-N-difucopentaose II is an oligosaccharide first isolated from human milk by recycling chromatography in 1988. Is resistant to enzymic hydrolysis in the gastrointestinal tract of the infant; it is postulated that they reach the large intestine where they serve as substrates for bacterial metabolism. Oligosaccharides in human milk represent a group of bioactive molecules that have evolved to be an abundant and diverse component of human milk, even though they have no direct nutritive value to the infant.
