Its both!
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
Lecithin is what you are looking for, not lethicin. It is a phospholipid. Which means that it has a phosphate part and a lipid part. This means that it has both water loving and water hating parts which makes it great for use in the body in places like the mucous membrane of our gut. It is not a protein.
Lipids. Naturally there are many different types.
A phospholipid bilayer is a two-layered arrangement of phosphate and lipid molecules that form a cell membrane, the hydrophobic lipid ends facing inward and the hydrophilic phosphate ends facing outward. Also called lipid bilayer.http://dictionary.infoplease.com/phospholipid-bilayer
If it is mixed well.
neither. Fructose is a sugar, or carbohydrate.

cheese is a lipid and a protein
Protein= Ribosomes. Carbohydrate= Plasma Membrane Lipid= Lipid Bilayer
A lipid

It is a type of fat, a lipid.
lipid, its fat. Its Lipoprotein or we can say Protein-lipid, a combination of protein and lipid.
Neither, a carbohydrate is a sugar, proteins are amino acids, lipids are fats! Nucleotides are what make DNA and RNA! They are considered a monomer
