Explanation:
a. used to make one end of a lipid molecule hydrophillic - -PO4^3-
Phosphate group is Hydrophilic because it is the soluble end of the lipid and it dissociates in water.
b. makes attached molecule more water soluble - -OH
-OH reacts with water molecules readily to form hydrogen bonds.
c. strongly charged - -PO4^3-
Phosphate group has a 3- charge which means it has 3 electrons gor bonding.
d. nonpolar and very stable - -CH3
Methyl group is non polar because it does not form any hydrogen bond with water. The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed bonds -
e. polar and forms hydrogen -OH
-OH readily forms hydrogen bonds with water molecules.
f. can be added to DNA to regulate gene expression - -PO4^3-
Gene expression is very common in Eukaryotes like bacteria cells which is via phosphorylates.
