Answer:
Biuret test does not work for all kinds of proteins. It only works with proteins and peptides that have 2 or more peptide bonds.
Explanation:
The Biuret test is used to determine proteins and polypeptides that contain 2 or more peptide bonds.
It is made of potassium hydroxide and cupric sulfate, along with sodium and potassium tartrate.
It consists of treating a protein with Cu ++ in alkaline medium, producing a violet coloration by forming a coordination complex between the Cu ++ and the free electron pairs of the nitrogens of the amino groups of the peptide junction. At least two peptide bonds are necessary for the reaction to take place.
Therefore, this test does not serve to determine the amount of amino acids and peptides with a single peptide bond such as: tyrosine (amino acid), tryptophan (amino acid), alanine (amino acid), aspartame (peptide)
The answer is TRUE.
If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.
Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.
