Alpha glucose and beta glucose with a beta 1 4 glycosidic linkage!
Two Monosaccharides
Lactose is composed of two monosaccharides: glucose and galactose.
Monosaccharides are single sugar molecules, while disaccharides are made up of two monosaccharides joined together. Disaccharides are formed through a dehydration reaction, where a water molecule is removed to bond the two monosaccharides together.
If two monosacharides are together, this then means it is classified as a disacharide. However, if it has many more than just two monosacharides 'joined together', then that means it is classified as a polysacheride. Fat cell structures are commonly known as triglycerides, and they consist of fatty acid chains and glycerol.
Fructose and glucose are found in sucrose.
Glucose and fructose are the two monosaccharides that join to form table sugar, also known as sucrose.
A disaccharide results when two monosaccharides join together.
A molecule of water is lost during the process of dehydration synthesis, which binds two monosaccharides together.
The reaction is called "Dehydration Synthesis".
Two Monosaccharides
Lactose is composed of two monosaccharides: glucose and galactose.
When two monosaccharides join to form a disaccharide through a condensation reaction, a molecule of water is removed, not added. This process occurs through the formation of a glycosidic bond between the two monosaccharides.
During dehydration synthesis, a molecule of water is removed as two monosaccharides join together to form a disaccharide. In the case of joining 5 monosaccharides to form a polysaccharide, four water molecules would be removed in total. A covalent bond, known as a glycosidic bond, forms between the monosaccharides to create the polysaccharide.
If the glycosidic bond is broken by hydrolysis, a disaccharide will degrade in two monosaccharides. For example, a sucrose will generate one molecule of glucose and one of fructose, lactose will give a molecule of galactose and one of glucose, and maltose, isomaltose, and cellobiose (that differ only in the glycosidic bond) will generate two molecules of glucose.
Disaccharides are formed by a dehydration reaction (condensation) between two monosaccharides, resulting in the formation of a glycosidic bond. This process involves the removal of a water molecule to join the two monosaccharides together. Common examples of disaccharides include sucrose, lactose, and maltose.
Maltose is made up of two glucose molecules.
a water molecule is also formed (a.k.a. H2O)
