The Organic Molecule in Cell Membranes That Forms Self Antigens

Question

The organic molecule in cell membranes that forms self antigens attached to proteins is:
A)glucose
B)cholesterol
C)phospholipids
D)oligosaccharides

Accepted Answer

Oligosaccharides are the organic molecules in cell membranes that form self antigens attached to proteins. These antigens are used by the immune system to recognize self from non-self cells. The other choices, glucose, cholesterol, and phospholipids, are also important components of cell membranes, but do not form self antigens.
