Which macromolecule can you live without?

Sometimes the energy content of food is expressed in kilojoules (kj), a metric unit. One kcal equals 4.184 kj.

What molecules contain the most energy per gram?

Fats supply the most energy at 9 calories per gram. Carbohydrates and proteins each provide 4 calories per gram for use as energy in the body.

Can protein convert to fat?

Dietary protein is used to replace proteins which were previously broken down and used by the body. Extra protein does not get stored. Instead, excess amino acids get converted to carbohydrate or fat.

What is the difference between a calorie and a calorie?

The physical unit “calorie” is the energy required to increase the temperature of one gram of water by 1 degree Celsius, and the dietary Calorie is a kilocalorie = 1000 calories. It is common practice to just use the unit kcal to avoid the confusion between “calorie” and “Calorie” .
