Bond Holding fatty acid) Phosphodiester bond
Monomers Together (covalent) + hydrogen
Glycosidic bond (Covalent) Lipids don’t form true polymers. Peptide bond (covalent)
bonds between strands
(special for lipids) They are held together in structures (DNA)
by hydrophobic interactions.
Not a polymer backbone.
Glycerol is the backbone in N-C-C
Backbone of
Carbon chain (Sugar ring) triglycerides and phospholipids. Sugar–phosphate backbone
Polymer (repeating peptide backbone)
Fatty acyl chains are hydrocarbon
tails.
