In figure 30-4 , which structure represents unsaturated fat? what structure represent saturated fat? at room temperature, what state is each type of fat? state whether each type of fat is associated with heart problems. given example of each type of fat

The A is unsaturated fat and B is saturated fat.

Saturated fatty acids are solid at room temperature. While unsaturated fatty acids are liquid at room temperature (due to the double bond) and this makes the molecule fragile, susceptible to contamination.

Consumed in excess, saturated fatty acids increase the synthesis of bad cholesterol, the risk of diabetes, hypertension and therefore cardiovascular problems.

To reduce the level of bad blood cholesterol, it is better to opt for unsaturated fatty acids, which are called "good" fats for cardiovascular health. But it is necessary in this case to avoid the saturated fatty acids (industrial).

i believe the answer would be b. hope it : )
