You can do this:
Materials Needed:
1. Skim milk, 125 mL 2. Beaker, 250 mL
3. Vinegar (acetic acid), 25 mL 4. heat source
5. Sodium bicarbonate (baking soda), 1g 6. Funnel and filter paper
7. stirring rod 8. water, 30 mL
9. Graduated cylinder, 125 mL
Strategy:
1. Place 125 mL of skim milk in a 250 mL beaker.
2. Add 25 mL of vinegar, which is an acidic solution.
3. Gently heat milk and stir constantly until small lumps begin to form.
4. Remove beaker from heat and continue to stir until no more lumps form.
5. Allow lumps to settle.
6. Filter the solid (curds) from the liquid (whey) using funnel.
7. Gently press the filter paper around the curds to squeeze out the excess
liquid through the filter paper.
8. Return the solid to the beaker
9. Add 30 mL of water to the solid and stir
10. Add 1/2 tsp. of baking soda to neutralize vinegar, bubbles should appear.
Add a little more baking soda until no more bubbles appear.
11. The substance in the beaker is glue. Test the adhesive properties,
including waterproof property.
I am doing this for a science experiment this year and it worked

What is the principle of heat coagulation test for proteins?
The principle of the heat coagulation test for proteins is based on the denaturation and coagulation of proteins when exposed to heat. By heating a solution containing proteins, the proteins unfold and aggregate, forming a visible clot or precipitate. This test is commonly used to assess the presence of specific proteins by noting the formation of a clot or precipitate upon heating.
What purpose for amino acid?
Amino acids are the building blocks of proteins in the body. They have several important functions, including building and repairing tissues, supporting immune function, and producing enzymes and hormones. Amino acids are also used as a source of energy when needed.
What is the effect of high heat and pH on proteins?
High heat can denature proteins by disrupting the non-covalent bonds that maintain their structure, leading to loss of function. High pH can also denature proteins by altering the charge distribution within the protein, affecting its interactions and structure. Both high heat and pH can affect the shape and function of proteins, ultimately leading to their inactivation.
What is the chemical term for uncoiling proteins dues to heat or acid?
proteins are typically DENATURED by heat or acid.
What happens to proteins dissolved in that water when you heat it to 100 degrees celsius?
When water is heated to 100 degrees Celsius, proteins may denature and unfold, disrupting their specific 3D structure. This can lead to loss of their biological function and possibly aggregation, causing the proteins to clump together. Additionally, some proteins may hydrolyze or break down into smaller peptides or amino acids due to the high temperature.
How are proteins changed when they are cooked?
Proteins are the result of amino acids processed through heat. This makes the protein harder to digest.
What dissolved food does plasma carry?
itcontains water, amino acids, proteins, carbohydrates, harmones, urea and heat energy.
Why do abnormal elevated temperatures degrade proteins?
The heat breaks the hydrogen bonds between the amino acids, and the shape is changed.

Effects of heat on fats and oils?
effect of heat on fire On heating the fatty acids and glycerol is produced.Heamoglobin in meat decomposes and changes the red colour in brown.
What is the effect of heat and acids on milk?
If the substance "milk" comes into direct contact with either of the mentioned substances/forces, the milk proceeds to "go off".
Does heat shock protein denature by heat or not?
No, heat shock proteins do not denature in response to heat. They are specialized proteins that are produced in response to increased temperatures to help protect other proteins from denaturation and promote proper folding and function.
What energy and particles does the body harvest from digestion?
Heat energy, mechanic energy, and new chemical energy.
What is the chemical term for uncoiling proteins dues to heat or acid?
proteins are typically DENATURED by heat or acid.
