A macromolecule is a very large molecule made up of smaller units called monomers. The monomers may be the same or slightly different. Macromolecules are formed by dehydration reactions in which water molecules are removed from the formation of bonds. Four main types of macromolecules control all activities. They are proteins, carbohydrates, nucleic acids and lipids. Their monomers are amino acids, sugars, nucleosides and glycerol and fatty acids.
The SuperCab is Ford's version of an extended cab. Instead of having four full doors, as with the crew cab, the SuperCab has a full passenger door, full driver's door and two half doors in the back.
In 1997, SuperCab trucks received a rear opening half-door on the passenger side, followed by an identical door on the driver's side two years later. Ford resurrected the SVT Lightning after a 3-year absence, and in 2001 the F-Series SuperCrew became the first half-ton pickup truck with four full doors.n 1997, SuperCab trucks received a rear opening half-door on the passenger side, followed by an identical door on the driver's side two years later.
