* 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.
Starch is a polysaccharide composed of glucose units, while proteins are polymers of amino acids. Starch molecules have a linear structure with alpha-linked glucose units, while proteins have a complex three-dimensional structure due to the folding and interactions of amino acid side chains. Overall, both starch and proteins are important macromolecules that serve different functions in living organisms.
starch'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.
What is the chemical reaction between lugols solution and a starch?
The reaction between Lugol's solution (iodine) and starch forms a blue-black complex. Iodine molecules fit into the helical structure of starch molecules, producing this characteristic color change. This reaction is commonly used to test for the presence of starch in a solution.
Is protein a starch?
No, protein is not a starch. Starch is a type of carbohydrate found in foods like grains and potatoes, while protein is a macronutrient found in foods like meat, dairy, and legumes. Both provide energy, but they have different functions in the body.
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.
How is the structure of starch related to its function?
The structure of starch is composed of glucose monomers linked together in long chains. This structure allows starch to be broken down into glucose molecules during digestion, providing a source of energy for cells. Additionally, the branched structure of starch makes it compact and easily stored in plant cells for later use.
Does pea protein have starch?
Protein is not a starch.
Is the major compound that makes up skin a sugar starch protein or nucleic acid?
The major compound that makes up skin is protein. Collagen and elastin are the two main proteins in skin that provide structure, strength, and elasticity.
Is Starch molecules bigger than protein molecules?
Yes, starch molecules are generally larger than protein molecules. Starch is a polysaccharide made up of many glucose molecules linked together, while proteins are composed of amino acids linked in chains. This difference in molecular structure contributes to the varying sizes of the molecules.
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.
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.
Are English pea are they a starch?
They have starch, protein, and other nutrients such as vitamins and minerals.
Does egg whites have starch?
Very little starch. Mostly protein and water.
What does it mean when you put iodine on a starch food?
When iodine is added to a starch food, it forms a dark blue or black color indicating the presence of starch. This reaction occurs due to the formation of a complex between the iodine and the helical structure of starch molecules.
Which of the following nutrients begin to digest in the mouth starch protein fats or vitamins?
Starch
