The correct statement(s) among the following is/area)Secondary structu...
Explanation:
Statement a: Secondary structure of a polypeptide describes the number and type of amino acid residues.
This statement is incorrect. Secondary structure of a polypeptide describes the local folding of the polypeptide chain into regular structures such as alpha helices and beta sheets, which are stabilized by hydrogen bonds between the backbone atoms. It does not describe the number and type of amino acid residues.
Statement b: Uracil is a pyrimidine nucleobase.
This statement is correct. Uracil is a pyrimidine nucleobase that pairs with adenine in RNA and replaces thymine in DNA.
Statement c: Natural fatty acids have odd number of carbon atoms.
This statement is incorrect. Natural fatty acids typically have an even number of carbon atoms, usually between 12 and 24.
Statement d: Reaction of (D)-glucose with Ca(OH)2 gives a product mixture containing (D)-fructose, (D)-mannose, and (D)-glucose.
This statement is correct. When (D)-glucose is treated with Ca(OH)2, it undergoes isomerization to form a mixture of (D)-fructose, (D)-mannose, and (D)-glucose. This reaction is known as the Lobry de Bruyn-van Ekenstein transformation.
Therefore, the correct statements are b and d.
