l. Triglycerides, which are the major component of vegetable oil as well stored fat in animals, are composed of three fatty acids and glycerol. Phospholipids are found primarily in the cell membranes of living systems, of which they are the major component.
edit Size. T. Rex adults were a significantly larger compared with allosaurus adults. An allosaurus adult was between 8.5 and 12m in length (28-39 ft), while the average T. Rex adult was about 12-15m long (40-50 ft). The average height of an allosaurus was 17ft (a little over 5m) while T. Rex was about 23ft (7m) tall on average. The T. Rex was also substantially heavier at 14,000 lbs compared to the allosaurus at 4,000 lbs.
2. Is Acrocanthosaurus as big as T. rex? Not quite. But it was the largest North American predator of its time! Acro grew to nearly 40 feet long and 13 feet tall (measuring from the ground to the top of the pelvis). T. rex was about the same length, but taller and one to two tons heavier. Acro weighed 5,280 pounds (2.6 tons).
