Question36 asks which statement about lipids is INCORRECT. Review each option in turn.
Option 1: 'In our body, lipids can protect internal organs from shock, as well as insulate against cold.' This is accurate: adipose tissue cushions organs and provides thermal insulation, helping protect against mechanical shock and temperature changes.
Option 2: 'The melting point is lower in oils due to a predominance of saturated fatty acids in triglyceride, making it a liquid at room temperature.' This is the incorrect statement. In reality, oils have a predominance of unsaturated fatty acids, not saturated, which lowers the melting point and makes them liquid at room temperature. Saturated fats tend to be solid at room temperature because they pack tightly; unsaturated fats introduce kinks that prevent tight packing, lowering the melting point.
Option 3: 'Triglyceride is the chief form of stored energy in our bodies.' This is true: triglycerides store energy efficiently in adipose tissue, providing a large energy reserve.
Option 4: 'In foods, lipids can provide that feeling of fullness, as well as essential fatty acids.' This is correct: lipids contribute to satiety and supply essential fatty acids that the body cannot synthesize.
Option 5: 'From an evolutionary perspective, it is believed humans may be ‘fatter’ than other primates to power our bigger brains' This reflects a hypothesis about energy storage and brain evolution and is often discussed in anthropological contexts, making it a reasonable statement.
In summary, the only statement that misstates lipid chemistry is Option 2, which incorrectly describes saturated versus unsaturated fats in oils and their melting points; all other options describe true or acceptable aspects of lipids.
