How does buiret solution react to egg whites

Biology
1 answer:
bazaltina [42]3 years ago
7 0

Answer: The blue colour of a biuret solution changes to violet.

Explanation: Biuret solution is a reagent that is used to test for the presence of protein in a substance.

A Biuret solution is composed of sodium hydroxide and copper II sulphate. Copper ions give the reagent its characteristic blue colour. Copper ions react with peptide bonds in the protein in an alkaline solution to form a Biuret compound with a violet colour. The copper ions which have two positive charges are reduced to a positive charge, thereby causing a colour change.

What are the roles of covalent bonds and hydrogen bonds in the structure of DNA?
Vinil7 [7]
For the answer to the question above,
 <span>DNA is made up of two nucleotide strands. The nucleotides are connected together by covalent bonds within each strand. The sugar of one nucleotide forms a covalent bond with the phosphate group of another. The two strands themselves are connected by hydrogen bonds. The hydrogen bonds are found between the bases of the two strands of nucleotides. Adenine forms hydrogen bonds with thymine whereas guanine forms hydrogen bonds with cytosine. This is called complementary base pairing</span>
