I would have said "phospholipid" except that it's hardly a "macromolecule" by my standards (I'm a polymer chemist by training).
The phosphate ion (PO43-) is considered polar because it has a net negative charge and is asymmetrical in shape due to the arrangement of oxygen atoms around the central phosphorus atom. The presence of the charge and the uneven distribution of electrons make it polar.
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.
Phosphate molecules.
The molecule is nonpolar.
No, polar solutes are generally not soluble in nonpolar solvents.
No, a phosphate group is polar due to the presence of electronegative oxygen atoms. It contains both polar and nonpolar characteristics because of its negative charge and the nonpolar hydrophobic tails in biological molecules it can interact with.

It is nonpolar
The compound with both a non-polar tail and a polar head is called an amphiphilic molecule. An amphiphilic molecule can form micelles. These such micelles is how detergents dissolve dirt. A big example of micelles are phospholipids.

Phosphate groups are polar because they contain highly electronegative oxygen atoms that create a dipole moment, attracting water molecules and forming hydrogen bonds. This polarity allows phosphate groups to interact favorably with the aqueous environment, making them hydrophilic. In contrast, the fatty acid tails of phospholipids are nonpolar and hydrophobic, which helps to form the bilayer structure in cell membranes, with the polar heads facing outward and the nonpolar tails facing inward.
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.
Yes, they do. Phospholipids contain a hydrophilic (polar) head and a hydrophobic (nonpolar) tail. The hydrophilic (polar) head contains the phosphate groups, which account for the reason why the head is polar since each phoshpate has a net charge of -2. The tail consists of long chains of hydrocarbons, which are nonpolar/hydrophobic due to the symmetry of the chains.
