Description

WetSolid

Beta-maltose is a maltose that has beta-configuration at the reducing end anomeric centre. It has a role as a geroprotector.|A dextrodisaccharide from malt and starch. It is used as a sweetening agent and fermentable intermediate in brewing. (Grant and Hackh's Chemical Dictionary, 5th ed)
