To solve this problem, we need to identify the substances that contain glycosidic and peptide bonds. Let's analyze the given options:$\newline \bullet$Glycosidic bond: This is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which can be another carbohydrate.$\newline \bullet$Peptide bond: This is a covalent chemical bond formed between two amino acid molecules.$\newline$Now, let's evaluate each option:$\newline \bullet$Option 1: Glycerol, trypsin$\newline$ - Glycerol is a simple polyol compound and does not have glycosidic bonds.$\newline$ - Trypsin is a protein (enzyme) and contains peptide bonds.$\newline$ - Therefore, this option does not contain both types of bonds.$\newline \bullet$Option 2: Cellulose, lecithin$\newline$ - Cellulose is a polysaccharide and contains glycosidic bonds.$\newline$ - Lecithin is a phospholipid and does not contain peptide bonds.$\newline$ - Therefore, this option does not contain both types of bonds.$\newline \bullet$Option 3: Inulin, insulin$\newline$ - Inulin is a polysaccharide and contains glycosidic bonds.$\newline$ - Insulin is a protein hormone and contains peptide bonds.$\newline$ - Therefore, this option contains both glycosidic and peptide bonds.$\newline \bullet$Option 4: Chitin, cholesterol$\newline$ - Chitin is a polysaccharide and contains glycosidic bonds.$\newline$ - Cholesterol is a sterol and does not contain peptide bonds.$\newline$ - Therefore, this option does not contain both types of bonds.$\newline$Based on the analysis, the correct option is Option 3: Inulin (glycosidic bond) and Insulin (peptide bond).
