Appearence
Lipopolysaccharides (LPS) are large, complex molecules which can vary widely in structure, but generally have a rough appearance. LPS typically appears as a white or off-white amorphous powder when isolated. However, in its natural state as part of the outer membrane of Gram-negative bacteria, it may contribute to a smoother membrane surface.
