Question

which of the following is false about fatty acids? A) the membrane contains mostly unsaturated fatty acids. B) melting point of fatty acids decreases with increase in saturation. C) naturally occurring unsaturated long-chain fatty acid are nearly trans. D) lipids in tissue that are subjected to cooling are more unsaturated​

Answer 1

Answer:

C) naturally occurring unsaturated long chain fatty acid are nearly trans

Explanation:

*they have any configuration not only trans

Answer 2

Answer:

The correct option is C).

Explanation:

• In both our bodies and the food we eat, fatty acids serve as the foundation for fat.
• A molecule known as a triglyceride is created when three fatty acid molecules are linked together.
• In comparison to saturated fatty acids with the same number of carbon atoms, unsaturated fatty acids have lower melting points.
• Careful analysis of molecular geometries can reveal the cause of this phenomenon.
• Tetrahedral bond angles on carbon lead to somewhat straight, albeit zigzag, molecular geometry for saturated fatty acids.
• This chemical structure enables the "stacking" of several fatty acid molecules very tightly.
• As a result, melting points are typically high due to intimate intermolecular interactions.

Long-chain saturated fatty acids are almost trans-configured.
