Lipids
• Triacylglycerols• Phospholipids• Steroids and Sterols• Others
Triacylglycerols are…
composed of fatty acids (VVVV) linked to a glycerol
(C3H5(OH)3) molecule through an ester bond
Fatty acids are…
long chains of carbon and hydrogen atoms linked by
covalent bonds with a carboxylic acid terminus
fatty acids are linked to glycerol via an ester bond
Phospholipids are composed of two fatty
acid chains and a phosphate group linked
to a glycerol molecule through an ester bond
phospholipids are amphipatic
Steroids are…
four heterocyclic ringed molecules composed of
carbon and hydrogen with various functional groups
attached to this ensemble
