A subunit of lipids, it is a simple polyol (sugar alcohol) compound
Typically transmembrane proteins with hydrophobic regions that completely span the hydrophobic interior of the membrane.
Lipids are made of subunits, namely glycerol and fatty acids, they are not polymers
The simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH2O.
Protein appendages loosely bound to the surface of the membrane and not embedded in the lipid bilayer.
A molecule that is a constituent of the inner bilayer of biological membranes, having a polar, hydrophilic head and a nonpolar, hydrophobic tail.
membranes are composed of a phospholipid bilayer – that means there are two layers of phospholipids arranged with their hydrophobic tails shielded from the aqueous environment of the cell and the hydrophilic heads in contact with it.
A polymer of up to over a thousand monosaccharides, formed by dehydration reactions.
