In starch, glucose monomers are linked together primarily by alpha-1,4-glycosidic linkages. Additionally, branching occurs in amylopectin through alpha-1,6-glycosidic linkages, which create side chains in the structure. These linkages allow starch to serve as an effective energy storage molecule in plants.
What else can I help you with?
The enzyme amylase can break glycosidic linkages between glucose monomers only if the monomers are the α form Which of the following could amylase break down?
can break down glycogen and starch (ex: amylopectin or amylose). But not cellulose which is made from beta form glucose. Amylase, present in saliva, breaks down starch into maltose and simple sugars. The maltose is then broken down in the small intestine by maltase into glucose.
What types of bonds linke cellulose monomers together?
Cellulose monomers are linked together by glycosidic bonds. These bonds form between the hydroxyl groups of adjacent glucose molecules, creating long chains of cellulose polymer.
What is removed when joining the individual glucose monomers together?
When joining individual glucose monomers together to form a polysaccharide like starch or glycogen, a water molecule is removed in a condensation reaction to form a glycosidic bond.
What are the monomers of complex carbohydrates?
The monomers of complex carbohydrates are simple sugars, or monosaccharides, such as glucose, fructose, and galactose. These monosaccharides join together through glycosidic bonds to form polysaccharides like starch, cellulose, and glycogen.
What are the two monomers included in a sucrose polymer?
Sucrose is a disaccharide composed of two monomers: glucose and fructose. These two simple sugars are linked together by a glycosidic bond. Sucrose is commonly found in plants and serves as an important energy source.
The enzyme amylase can break glycosidic linkages between glucose monomers only if the monomers are the form?
alpha helix
What monomers make up glycogen?
Glycogen is made up of glucose monomers. These monomers are combine in alpha-1,4 linkages with alpha 1,6 linkages used to create branches. Glycogen also has a small protein component that is used to initiate the glycogen polymer called glyocgenin.
Does glucose plus glucose make sucrose?
Fructose. Sucrose is the disaccharide made from two monosaccharides, glucose and fructose. The other disaccharides are lactose (glucose and galactose) and maltose (glucose and glucose). The monomers are bonded together through glycosidic linkages.

In which polysaccharides are all glycosidic linkages?
In polysaccharides, all glycosidic linkages can be found in cellulose and chitin. Cellulose consists entirely of β(1→4) glycosidic linkages between glucose units, providing structural support in plant cell walls. Chitin, found in the exoskeletons of arthropods and fungal cell walls, is composed of N-acetylglucosamine units linked by β(1→4) glycosidic bonds. Both polysaccharides exhibit a consistent type of glycosidic linkage throughout their structure.
What are monomers of carbohydrate?
Monosaccharides are monomers of carbohydrates. Some monosaccharides are glucose and fructose. When two monomers combine through a glycosidic bond, they form what is called a disaccharide.
What is the bond joining monomers of starch?
The bond joining monomers of starch is a glycosidic bond. It forms between the hydroxyl group of one glucose molecule and the anomeric carbon atom of another glucose molecule, resulting in a covalent linkage between the monomers.
STarch is held together by peptide bonds not glycosidic linkage?
This statement is incorrect. Starch is a polysaccharide composed of glucose units linked together by glycosidic bonds, not peptide bonds. Peptide bonds are formed between amino acids in proteins, not in carbohydrates like starch.
