Answer:
True.
Step-by-step explanation:
Proteins are macromolecules formed by one or more polypeptides (amino acid polymers) which are uniquely arranged. They all consist of carbon, hydrogen, oxygen, nitrogen and sulfur.
Proteins are extremely important to living things, for example, responsible for forming more than 50% of the dry mass of most cells. In addition, they act as catalysts (alter the speed of a reaction), in the body's defense and in many other important functions.
In short, we can say that protein is a necessary nutritional material, made up of amino acids, needed in our diet to maintain muscle.
Protein is very important both for people who want to gain muscle mass and for people who just want to lose weight and tone their muscles. For tissue repair or growth to occur, protein must be ingested at constant intervals throughout the day. If this does not occur you will experience no or very little muscle growth.
