Question

which of the following will behave most similarly to this molecule in water? which of the following will behave most similarly to this molecule in water? a. a polypeptide with nonpolar r groups b. a phosphate group with a short fatty acid tail c. a polysaccharide chain like glycogen as a group, share your reasons for your answer choices. be able to find all the described molecules in your notes and share any other similarities and differences you might see.

Explanation:

The given molecule appears to be a triglyceride with long - chain fatty acids. Nonpolar molecules tend to have similar behavior in water (hydrophobic behavior). A polypeptide with nonpolar R groups will also be hydrophobic and have similar behavior in water as it will avoid water interactions. A phosphate group with a short fatty acid tail has a polar head and is amphipathic. A polysaccharide chain like glycogen is hydrophilic due to the presence of many hydroxyl groups.

Answer:

A. A polypeptide with nonpolar R groups
