Question

Quizplus · Accepted Answer

Proteins help build and maintain various tissues in the body, including muscles, bones, enzymes, and red blood cells. They are not a significant source of calories like carbohydrates and fats. Proteins obtained from animal sources such as meat, eggs, and milk are considered high-quality proteins as they contain all the essential amino acids required by the body. However, some plant sources of protein may lack certain essential amino acids, making them incomplete proteins. Therefore, a balanced diet is necessary to ensure adequate protein intake. Triglycerides are a type of lipid, not protein.
