Morphology

lipopolysaccharide = polysaccharide (semi-transparent) = lipo + poly + saccharide

The term is built from standard scientific morphemes, but its specialized biochemical meaning is not directly guessable for an average learner.

Etymology

Lipopolysaccharide comes from parts you can read: lipo- means 'fat' and poly- + saccharide means 'many sugars'. It is a molecule made of fat with many sugars on the outside of some bacteria, which is why it can cause a strong reaction in the body's immune system.
