Why Glucose is a polar molecule?

The structure of glucose is as such: as can be seen, there are multiple instances of -OH groups which are highly electronegative and draw electrons away from the carbon molecules. This leads to a skewed charge distribution. It is thus polar.

In respect to this, what is meant by polar uncharged?

7 amino acids are polar uncharged: gly, ser, cys, asn, gln, tyr, thr. These amino acids are relatively hydrophilic (water loving) because they possess polar functional groups (in side chains) i.e. oxygens and nitrogens, which can participate in hydrogen bonding with water so capable of interacting with water.

Is a charged molecule polar?

The geometry of atoms in polar molecules is such that one end of the molecule has a positive electrical charge and the other side has a negative charge. Non-polar molecules do not have charges at their ends.

Are polar molecules neutral?

The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
