Roles Classification
Biological Role(s): macronutrient
Any nutrient required in large quantities by organisms throughout their life in order to orchestrate a range of physiological functions. Macronutrients are usually chemical elements (carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur) that humans consume in the largest quantities. Calcium, sodium, magnesium and potassium are sometimes included as macronutrients because they are required in relatively large quantities compared with other vitamins and minerals.
