검증된 단계별 안내1
Step 1: Begin by understanding the basic composition of nutrients. Nutrients are classified into different categories such as carbohydrates, proteins, vitamins, and minerals. Each class has distinct chemical properties.
Step 2: Recall that organic molecules, such as carbohydrates, proteins, and vitamins, contain carbon as a fundamental element. Organic chemistry is the study of carbon-containing compounds.
Step 3: Minerals, on the other hand, are inorganic substances. They are composed of elements like calcium (Ca), iron (Fe), and potassium (K), which do not contain carbon in their structure.
Step 4: Compare the chemical composition of each nutrient class. Carbohydrates, proteins, and vitamins are organic and contain carbon, while minerals are inorganic and do not contain carbon.
Step 5: Conclude that the class of nutrients that does NOT contain carbon is minerals, based on their inorganic nature and chemical composition.
