Verified step by step guidance

Identify the two monosaccharide units involved in the glycosidic linkage. In the image, you can see two glucose molecules.

Determine the carbon atoms involved in the glycosidic bond. The bond is formed between the anomeric carbon of one sugar and a hydroxyl group of another sugar.

Locate the anomeric carbon in each glucose unit. The anomeric carbon is the carbon attached to two oxygen atoms. In glucose, this is typically carbon 1.

Observe the linkage between the two glucose units. The oxygen bridge connects the anomeric carbon (C1) of the first glucose to the C4 of the second glucose.

Conclude that the glycosidic linkage is a 1,4-glycosidic linkage, as it connects the C1 of one glucose to the C4 of the other glucose.
