Question

The presence of many c-c and c-h bonds causes fats to be

a.rich in energy
b.insoluble in water

Answer 1

inal answer:

The many C-C and C-H bonds in fats lead them to be rich in energy and insoluble in water, with saturation affecting their state at room temperature and their ability to be closely packed.

Step-by-step explanation:

The presence of many C-C and C-H bonds in fats makes them rich in energy because the chains of carbon atoms bonded to hydrogen atoms can store energy in a compact form. This characteristic accounts for the energy density of fats, as saturated fatty acids, with no carbon-to-carbon double bonds, form straight chains that can be packed tightly together. In contrast, unsaturated fatty acids have one or more double bonds, which introduce kinks and prevent tight packing, resulting in lower melting points and a liquid state at room temperature.

Fats are insoluble in water primarily due to the nonpolar nature of the C-C and C-H bonds, which do not interact favorably with the polar water molecules. This insolubility is an important property of fats as it allows them to serve as a long-term energy storage without disrupting the water-based cellular environments where biochemical reactions take place.

Answer 2

The right answer is both of them.

Take the example of fatty acids, it is an aliphatic chain carboxylic acid composed of 4 to 36 carbon molecules. The more carbons (and therefore the CC and CH bonds), the more the fatty acid will be rich in energy since it will give more ATP during its catabolism, and it will also be less and less soluble in water because the carbon chain is hydrphobic.
