Chemical Studies of Agar-Agar

Bulletin of the Agricultural Chemical Society of Japan, 1931
(1) Aqueous solution of λ acid gives colloid. This acid is stable in the combined form with alkalis or metals. But in the free state, it is unstable and easily decomposable. (2) The rotately power of this acid shows -31° and its composition as far as made clear is as follows:- Galactose 39.47% Pentose 8.17% SO4 ca.

AGAR-AGAR IN THE TREATMENT OF CONSTIPATION IN CHILDHOOD [PDF]

JAMA: The Journal of the American Medical Association, 1910
Agar-agar is prepared from hot water extracts of various species ofGelidiumand differs somewhat in its composition according to its origin. It is sold commercially in the form of strips about eighteen inches long, varying in thickness from that of a straw to that of the finger. It contains about 60 per cent. of carbohydrates, principally in the form of
