Question

I've figured about half of it out, but I need help with the remainder of it.

I have to apply the following properties to seven different molecules. The properties can/will be repeated and more than one can apply to the same molecule.

Properties:
Non-polar bonding
polar bonding
insoluble in water
soluble in water

Molecules:
Fructose
Glucose
Triglyceride
Cholesterol
Leucine
Serine
Cysteine

I really appreciate it. Thanks so much.
First to answer all with sources will get best answer :)

Answer 1

Triglyceride and cholesterol are insoluble in water while Fructose and Glucose (sugars) and Leucine, Serine and Cysteine (amino acids) are solube.

allof them are NON POLAR, they may only have dipole moments (if C-N or C-O bonds are present).

Answer 2

Insoluble in water: Triglyceride, Cholesterol
Soluble in water: Fructose, Glucose, Leucine, Serine, Cysteine

I don't know what you mean by polar or nonpolar bonding. They are all covalently bonded. They are all polar molecules.
