The presence or absence of carbon is what differentiates organic nutrients from inorganic nutrients. Carbohydrates, lipids, proteins and vitamins have carbon in their structure, making them organic. Water and minerals do not, so they are inorganic. Nutrition 101: Science of Nutrition / Science Courses.
Organic nutrients consist of carbohydrates, fats, proteins (or their building blocks, amino acids), and vitamins. Inorganic chemical compounds such as dietary minerals, water, and oxygen may also be considered nutrients.utrients needed in very small amounts are called micronutrients while those needed in large quantities are called macronutrients. The effects of nutrients are dose-dependent; shortages are called deficiencies.
