Besides water, your brain is mostly composed of

Question

BlackTom AI · Accepted Answer

When evaluating the composition of the brain aside from water, we consider what constitutes the majority of its remaining mass.
Option 1: protein. While proteins are essential for brain structure and function, they are not the single largest component after water; the brain contains substantial lipids as well as proteins, but lipids are typically more abundant than proteins in the brain’s dry mass.
Option 2: minerals. Minerals are present in the brain in smaller amounts, serving as cofactors and signaling ions, but they do not make up the largest share after water.
Option 3: lipids. This choice corresponds to the well-established fact that the brain has a high lipid content, which includes myelin and cell membranes; lipids constitute the major portion of the brain’s dry weight and are a primary component after water.
Option 4: carbohydrates. Carbohydrates are present in the brain primarily as glucose for energy and as part of glycoproteins and glycolipids, but they do not constitute the largest share after water compared with lipids.
Therefore, comparing the options, lipids best match the statement about the brain’s composition after water, while the others describe important but not dominating components. In summary, the lipid-rich nature of brain tissue is the primary reason this option is selected over protein, minerals, or carbohydrates.
