Option B refers to the role of lipids, not proteins, in lubricating joints and mucous membranes. Option C relates to vitamins and minerals, which are essential for preventing nutritional deficiencies, but not proteins. Lastly, option D incorrectly attributes the supply of fatty acids for insulation to proteins; this is primarily the function of fats. Thus, A stands out as the primary function of proteins.
