Which of the following statements are correct?
(A) A tripeptide had two peptide bonds.
(B) A pentapeptide contains five amino acids.
(C) Nucleotide is a product of base and sugar.
(D) In cellulose, \(\boldsymbol{\beta}\)-glycosidic linkages are present.
B, C, D
C, D only
A, B, D
A, C only
Solution
The explanations of given statements are as follows:
(A) A tripetide contains 3 amino acids linked by two peptide linkages. Thus, statement (A) is correct.
(B) A pentapeptide contains five amino acids linked by four peptide linkages. Thus, statement (B) is also correct.
(C) Nucleoside is a product of base and sugar. Thus, statements (C) is incorrect.
(D) In cellulose, \(\beta\)-D-glucose units are joined by glycosidic linkage between \(\mathrm{C}-\mathrm{l}\) of, one glucose and C-4 of the next glucose unit. Thus, statement (D) is a also correct.
Hence, option (c) is correct.
