BIOLOGICAL MACROMOLECULES
CARBOHYDRATES (carbon, hydrogen and oxygen)
MONOMER:
Monosaccharides: used to produce and store energy. Two monosaccharides combines form a disaccharide
fructose
galactose
glucose
POLYMER:
Polysaccharides: it is an important source of energy in animal cells, it helps with energy storage.
starch
cellulose
glycogen
REAGENT
Benedict's solution is added to a food and heated to test for reducing sugar :
Positive: It turns brick - red colour
Negative: It remains blue
Iodine solution is added to food to test for starch
Positive: it turns into a blue - black colour
Negative: it remains orange - brown
LIPIDS (carbon, hydrogen and oxygen)
MONOMER
fatty acids
glycerol
PROTEINS (carbon, hydrogen, oxygen and nitrogen)
MONOMER:
Amino - acids
POLYMER
Polypeptides
REAGENT:
NUCLEIC ACIDS (carbon, hydrogen, oxygen, nitrogen and phosphorous)
