Final answer:
The lipid linked to sugar is called a glycolipid, and the bond that connects the lipid to the sugar is known as a glycosidic linkage.
Step-by-step explanation:
The type of lipid that is linked to sugar is called a glycolipid. Glycolipids include molecules like glucocerebrosides, which have glucose as the sugar component, and galactocerebrosides, with galactose as the sugar component. Additionally, there are more complex glycolipids known as gangliosides, which have several sugar units attached. The connection between the lipid and the sugar in glycolipids is known as a glycosidic linkage. This linkage is crucial in the formation of cellular membranes and plays a role in cell recognition and signaling.
