STarch is held together by peptide bonds not glycosidic linkage?

No, starch is held together by a-1,4 glycosidic linkages. Carbohydrates, starch in this case, form glycosidic bonds while proteins (amino-acids) are the ones that form peptide bonds.!!!

How do starch turn into sugar?
Starch is made of many glucose molecules attached together by glycosidic linkage, which removes water from an equation. To break down starch into sugar, water needs to be added into the glycosidic linkages (a process called hydrolysis). The water completely breaks the starch in to individual sugar molecules.
What is the role of the enzymes of the digestive system in the complete breakdown of starch?
amylase (starch) to maltose maltase maltose to glucose Hydrolysis (of) Glycosidic bonds
How many differatn types of monomers are there in starch?
There is but one monomer of Starch - it is called Glucose. The word/term "saccharides" means sugars. STARCH is a sugar that plants store for future use.
What is mono-di and polysaccharides?
Monosaccharides are simple sugars which are made of a single sugar molecule eg glucose, lactose, fructose.Disaccharides are double sugars, formed from two monosaccharides linked together by a chemical bond (a glycosidic bond) eg lactose (milk sugar) consists of glucose and galactose combined together.Polysaccharides ("many" sugars) are made of many (eg hundreds) monosaccharides linked together by glycosidic bonds eg starch and cellulose are made from glucose molecules linked to form long chains.Read more: What_is_mono-di_and_polysaccharides
What is di polysaccharide?
Monosaccharides are simple sugars which are made of a single sugar molecule eg glucose, lactose, fructose. Disaccharides are double sugars, formed from two monosaccharides linked together by a chemical bond (a glycosidic bond) eg lactose (milk sugar) consists of glucose and galactose combined together. Polysaccharides ("many" sugars) are made of many (eg hundreds) monosaccharides linked together by glycosidic bonds eg starch and cellulose are made from glucose molecules linked to form long chains.
What is the macromolecule for glycosidic?
Macromolecules are carbohydrates, proteins, lipids and nucleic acids. Glycosidic linkage is a crucial bond that make simple sugars to complex carbohydrates. This linkage can be cleaved by enzymes such as amylases when there is a need of energy (starch or glycogen to glucose).
What is the component of starch?
Starch is a storage polysaccharide made of glucose (joined together by a 1-4 alpha glycosidic bond).
How do starch turn into sugar?

To break down starch into sugar, water needs to be added into the glycosidic linkages (a process called hydrolysis). The water completely breaks the starch in to individual sugar molecules.
What are startches made of?
Starch is made of a large number of glucose joined together by glycosidic bonds.
If 15 glucoses are bonded with each other by glycosidic bonds what macromolecule will be formed?
A bunch of glucose molecules joined by glycosidic bonds forms either glycogen or starch, depending on the way they are bonded together, i.e. depending on the nature of the glycosidic bond.
What is the name of the bond formed between glucose molecules when starch is formed?
Glycosidic Bond
What are the basic building blocks of starch?
Starch is a polysaccharide (a polymer composed of monosaccharides linked by glycosidic bonds) composed of alpha-D-glucose bonded by 1,4 glycosidic bonds in its amylose form, which is a linear chain, and both 1,4 and 1,6 glycosidic bonds in amylopectin, its branched form. In short: its monomer is alpha-D-glucose.
The structural difference between amylose and amylopectin?
Amylose is type of starch which is unbranched. Consisting 1-4 Alfa glycosidic linkage. It is not easy to digested and takes less space than amylopectin. Amylopectin is branched and consisting 1 alfa 1-6 linkage per 30 alfa 1-6 linkage. It is similar to glycogen expecting lower level of branching.
The difference between the chemical bonds in starch and those in cellulose?
they are all glycosidic bonds. in cellulose they are bonded so the sugars flip after every bond like a zig zag. in amylose it forms a right handed helix. in amylopectin it forms a right handed helix with a lot of branches (make it less soluble than amylose) Also Cellulose bonds are not hydrolyzed by human enzymes.
Differentiate between a sugar and a starch?
Plants store glucose in the form of starch.Starch can be separated into two fractions-amylose and amylopectin. Natural starches are mixtures of amylose (10-20%) and amylopectin (80-90%) Starch is a polymer of glucose molecules. It consists of a mixture of 2 polysaccharides:25% amylose - about 2000 glucose residues are linked by the alpha 1-4 glycosidic linkage. It is unbranched and forms a helix.75% amylopectin - branched chains about 100000 glucose units. Glucose is joined by the alpha 1-4 glycosidic linkage and at branched points the alpha 1-6 glycosidic linkages occur.
What is the role of the enzymes of the digestive system in the complete breakdown of starch?
amylase (starch) to maltose maltase maltose to glucose Hydrolysis (of) Glycosidic bonds
What are the differences between Maltose and Cellobiose?
Maltose is a disaccharide,composed of 2 α-D glucose recidues,linked together by an α-1,4 glycosidic bond,It is produced from the hydrolysis of starch and glycogen.WhileCellobiose is a repeating unit of cellulose,composed of two β-D-glucose recidues,linked together by a β-1,4 glycosidic bond.
