Question

Which of the following fatty acids is most likely to directly enter the bloodstream after absorption, rather than being absorbed at the intestinal wall and packaged into lipoproteins?

A) Saturated fatty acids
B) Monounsaturated fatty acids
C) Polyunsaturated fatty acids
D) Trans fatty acids

Answer 1

Saturated fatty acids are most likely to directly enter the bloodstream after absorption. Mono- and polyunsaturated fatty acids, as well as trans fatty acids, are more likely to be absorbed at the intestinal wall and packaged into lipoproteins.

Step-by-step explanation:

The fatty acids that are most likely to directly enter the bloodstream after absorption, rather than being absorbed at the intestinal wall and packaged into lipoproteins, are saturated fatty acids. Saturated fatty acids do not have any double bonds in their carbon chains, making them more compact and easily absorbed by enterocytes via simple diffusion.

Saturated fatty acids are most likely to directly enter the bloodstream after absorption. Mono- and polyunsaturated fatty acids, as well as trans fatty acids, are more likely to be absorbed at the intestinal wall and packaged into lipoproteins. On the other hand, monounsaturated, polyunsaturated, and trans fatty acids have double bonds in their carbon chains, causing them to be less compact and more likely to be absorbed at the intestinal wall and packaged into lipoproteins.
