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, ( )-glycosidic linkages are present.

Step-by-step 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, ( )-D-glucose units are joined by glycosidic linkage between ( C - l ) of, one glucose and C-4 of the next glucose unit. Thus, statement (D) is a als
