MACROMOLECULES
WHAT ARE THEY AND WHAT ARE THEY COMPOSED OF? -
VERY LARGE MOLECULES (LIPIDS)
COMPOSED OF POLYMERS MONOMERS -
CARBOHYDRATES
WHAT ARE THEY?
WHY ARE THEY IMPORTANT? -
2 MONOSACCHARADIES (1 SUGAR - GLUCOSE) ARE JOINED TO FORM DISACHHARIDES (2 SUGAR - MALTOSE) WHICH CAN BE JOINED TO OTHER SUGARS TO FORM POLYSACHHARIDES (STARCH)
SOURCES OF ENERGY / BUILD STRUCTURES IN PLANTS -
