Difference between chitosan and chitosanolioosaccharide
I          Digestibility                            Hard to be digested
	Well absorbed into the system
	
Materiality
	Insoluble in water
	Well soluble in Water
	
Recommended Intake
	Large amount
	Very small amount

	Chitosanoligosaccharide is well absorbed into the system, and therefore, even if a very small amount of chitosanoligosaccharide is taken (0.05~2g per day), its efficacy is fully accomplished.
	
Anti-Cancer Efficacy, Anti-Tumor Efficacy
	Weak
	Strong

	Hexasaccharide of chitosanoligosaccharide shows the highest efficacy.
	
Efficacy to Activate Intestinal Function
	None
	Existent

	Chitosanoligosaccharide activates Bifidus lactobacilli.
	
Efficacy to Activate Immunity
	None
	Very High

	Chitosanoligosaccharide is one of the oligosaccharide as contained in mother's milk
	
Efficacy to Activate Hepatic Function
	None
	Existent

	Because chitosanoligosaccharide is absorbed into the system, GOT and GPT become lowered. Therefore, the liver will never become fatty.
	
Relation with Mineral Elements (Calcium, Magnesium, Iron)
	It causes all minerals to be eliminated from the system
	Expediting absorption of most minerals into the system

	Though chitosan is a functional substance, it is not acknowledged as a health-aid-food for the reason that chitosan causes minerals required for people, such as iron, calcium, magnesium, etc., to be eliminated from the system. Specifically, chitosan adsorbs even the iron in the system and causes it to be eliminated from the system, and therefore, when a weak elderly person, a pregnant woman, an anemic patient or a child takes chitosan at ordinary times or in a large amount, a fatal problem is likely to take place.
	
Absorption by People, Plants or Animals
	Impossible
	Readily Absorbed

	A high molecular substance, chitosan cannot be absorbed by people, plants, or animals.  That is why it is called an indigestible diet fiber.   Meanwhile, a low molecular substance, chitosanoligosaccharide, is readily absorbed into the system.
	
Most people has a wrong knowledge that chitosan is a substance having a powerful functionality, but in fact, chitosanoligosaccharide has a variety of effects. Most of papers on chitosan as published so far were the results of studying on chitosan dosed to animals or plants. Of course, animals or plants were dosed with chitosan during such studies.  However, in fact, animals or plants cannot absorb chitosan directly thereinto, and therefore, they absorb low molecular chitosan which chitosan is decomposed into by a decomposing enzyme or a soil microorganism, called chitosanoligosaccharide.    Accordingly, the powerful functional substance is not chitosan but chitosanoligosaccharide.
