Lipids and carbohydrates differ in which of the following fundamental respects?
Schach [20]

Answer:

Carbohydrates are hydrophilic  whereas Lipids are hydrophobic.

Explanation:

Carbohydrates can be most commonly understood as hydrates of carbons. They generally contain more than two carbon atoms and are easily soluble in water, thus giving them the characteristics of hydrophilic compounds. Sugar and glucose are some of the important examples of carbohydrates.

On the other hand, lipids comprise a polar region, which attracts water and a much larger non-polar region, which repels water. This non-polar region dominates the polar region of lipid molecules thus making it a hydrophobic compound. Oils, fatty substances, steroids, and waxes are some of the important examples of Lipid molecules.

Another way to get it is from contaminated food, a lot like corona virus. When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat.
