What is the comparison between the structure of starch and protein?

∙ 15y ago
* Both are macromolecules (large molecules). * Both are polymers, having similar repeating units. * Starch is a polysaccharide, and specifically a polymer of glucose; proteins are polymers of amino acids. There are more than 20 different amino acids found in proteins.
* Starch consists of both branched and unbranched forms; the polypeptide chains of proteins are not branched (although there may be covalent and other bonds formed different points along chains). * Starch is essentially in the form of long fibrous molecules; proteins have complex secondary (coils, pleated sheets, loops, turns), tertiary (folding) and even quaternary (assembly of two or more chains in some proteins) structures that result in an enormous variety of three-dimensional shapes.

∙ 10y agostarch's role is sugar storage and it's joined by 1-4 linkages (#1 carbon to #4), glycogen does sugar release but's structure is more extensively branched, and cellulose's function is to strengthen srurcture and has a ring structure wiith an alpha configuration.

Does pea protein have starch?
Protein is not a starch.
Why is starch present in boiled amylase?
Boiled amylase as you probably figure has been boiled and since all enzymes are protein, their molecular structure is affected by the heating process. In other words, the amylase has become denatured and will not break down the starch and thus, the starch will remain in its present form.
Is protein a starch?
No. A protein is a chain of amino acids (a polypeptide). Starch is a carbohydrate (a large number of glucose molecules joined together).
How amylase breakdown starch?
To test starch: To test starch you take the food sample, and add iodine solution if the colour turns black this means starch is present. To test for protein: To test for protein, you take the food sample and add Biuret A and Biuret B and shake, if the colour turns lilac this means that protein is present.
What is the size difference fat polymers and starch and protein polymers?
Fat polymers usually vary in length and size, and starch is typically coiled. The protein polymers are round and oddly shaped.
Does pea protein have starch?
Protein is not a starch.
Is starch a carbohydrate protein or lipid?
Starch is a carbohydrate
What is the role for flour?
Flour contributes protein and starch to a baked products structure, the protein primarily being gluten. Flour may contribute protein and sugar for the Maillard reaction and/or yeast food for biological leavening. Flour also contains enzymes which may serve to weaken the structure.
Is the major compound that makes up skin a sugar starch protein or nucleic acid?
a sugar starch protein
What flower store starch?
All flowers (food) has starch and protein
Similarity of function between starch and protein?
1.starch is a carbohydrate 2.protein is polypeptide 3. both are bio molecule4. monomer of starch is glucose5. monomer of protein is amino acid 6.starch contain glycosidic bond 7.protein contain peptide bond
Why would you predict the pepsin would not digest starch?
Because Pepsin is the active form of a protein manufactured in the stomach.
Is Starch molecules bigger than protein molecules?
A protein molecule is quite a bit larger than a starch molecule.
Are English pea are they a starch?
They have starch, protein, and other nutrients such as vitamins and minerals.
The enzyme salivary amylase will act on starch but not on protein?
Lack protein.
Why is starch present in boiled amylase?
Boiled amylase as you probably figure has been boiled and since all enzymes are protein, their molecular structure is affected by the heating process. In other words, the amylase has become denatured and will not break down the starch and thus, the starch will remain in its present form.
Does egg whites have starch?
Very little starch. Mostly protein and water.
