Detailed explanation-1: -Maltose is composed of two molecules of glucose while sucrose is made up of one molecule of glucose and another one is fructose which is also a monosaccharide.
Detailed explanation-2: -Maltose is a disaccharide composed of which two monosaccharides? Explanation: Maltose, which is made up of two glucose monomers joined by an alpha-1, 4 linkage, is the correct answer.
Detailed explanation-3: -Monosaccharides are also called simple sugars since they are the most fundamental type of sugar. The term table sugar or granulated sugar actually refers to sucrose, which is a disaccharide made of two monosaccharides-glucose and fructose. Etymology: Ancient Greek (mónos, meaning “alone, single”) + saccharide.
Detailed explanation-4: -By Kris Sollid, RD Scientifically speaking, table sugar is sucrose, a disaccharide made of equal parts of two monosaccharides: fructose and glucose. Monosaccharides are single units of sugar and are often referred to as “simple” sugars.
Detailed explanation-5: -Maltose is produced by the enzymatic hydrolysis of starch (a homopolysaccharide) catalyzed by the enzyme amylase. Maltose is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose. The monosaccharide unit on the left is the hemiacetal of the -d-glucopyranosyl unit.
