BIOLOGICAL MOLECULES
PROTEINS
are made of
amino acids
are joined by
peptide bons
are used for:
Growth & repair
Making enzymes
Making hormones
Making antibodies
are tested by Biuret → turns purple
Water
acts as a solvent
helps with transport (blood, xylem, phloem)
controls temperature regulation
provides a medium for reactions
Enzymes
are a type of protein
work by speeding up reactions
follow the lock-and-key model
are affected by
Temperature
pH
Denaturation → leads to active site changing shape → enzyme stops working
CARBOHYDRATES
are made of
glucose
include
Starch
Glycogen
storage
Cellulose
function as a main energy source
are tested by
Iodine → results in blue-black (if starch present)
Lipids
are made of 1 glycerol + 3 fatty acids
are used for
Long-term energy storage
Insulation
Forming cell membranes
are tested by Ethanol emulsion → becomes cloudy white
