Description
Acemannan is a constituent of leaf juice of Aloe barbadensis. Acemannan is used in flavouring As noted from its structure, Acemannan is a mucopolysaccharide with mannoacetate as the monomer linked by -1,4- glycosidic linkages (3,6). This polymer is hydrophilic: 50 hydrogen bond acceptors, 19 hydrogen bond donors and logP of -3.27. Therefore, it s permeability (and hence bioavailability) has been scored to be 1 according to Lipinsky s rule of five (4)
