Triglycerides, phospholipids, and sterols
A fatty acid that has the maximum possible number of hydrogen atoms is known as a
Saturated fatty acid
The difference between cis- and trans- fatty acid is
The configuration around the double bond
Essential fatty acids:
Arrived to make substances that regulate blood pressure, among other functions.
Lecithins and other phospholipids in the body function as:
Emulsifiers

Protein
When carbohydrate is not available to provide energy for the brain, as in starvation, the body produces ketone bodies from:
Fatty acid fragments
Three hazards of fasting are:
Wasting of lean tissue, impairment of disease resistance, and disturbances of the body’s salt and water balance.
Two activities that contribute to the basal metabolic rate are:
Maintenance of heartbeat and body temperature
