Nutrition: Proteins

1 Proteins

To understand the composition, digestion, function in the body, etc., of a protein you will need to have some knowledge of chemistry.

As you read on, you will find that the word ‘mass’ is used, when you might expect to read ‘weight’. Scientifically speaking, the amount of matter in an object is called its mass, while the word ‘weight’ is used to describe the downward pull on the same object due to gravity. If you were to go to the Moon, your mass, measured in kilograms, would remain the same, but your weight would be much less because the force of gravity is only about one-sixth as strong on the Moon as on the Earth.
