Lipids provide the best source of
a. essential amino acids.
b. body-building materials.
c. glucose for the brain.
d. dense energy for the body.
D
Because lipids provide more energy per gram than any other nutrient (lipids provide 9 kcals per gram; protein and carbohydrate provide 4 kcals per gram and alcohol provides 7 kcals per gram), they are the best source of dense energy for the body. They do provide some body-building ma-terials: phospholipids are an important part of the structure of cell membranes. However proteins and minerals probably contribute more than lipids to building body structure. Lipids cannot be converted to glucose in the body.
