Also called glycitol or alditol. A general term for polyhydric alcohols obtained by reducing the carbonyl group of monosaccharides, and their homologues. Generally, the name is obtained by changing the ending -ose of the original sugar to -itol. It is widely distributed in the living world, especially the plant kingdom, in free or derivative form. Generally, it is easily soluble in water. It has a sweet taste. It has weak optical rotation, if any. It does not reduce Fehling's solution, and does not show mutarotation. When gently oxidized, it produces a mixture of the corresponding aldoses, ketoses, and aldonic acids, but when strongly oxidized, it gives sugar acids. In a broad sense, it also includes cyclic sugar alcohols (such as inositol and quercitol).
