Definition
an unbranched chain of carbon and hydrogens with a carboxyl group at one end
Term
carbon
Definition
element that forms the main chain of all lipids
Term
glycerol
Definition
a 3 carbon chain with one hydroxyl attached to each of the carbons
Term
carboxyl
Definition
a carbon with one double bonded oxygen and a hydroxyl attached
