The largest energy store in a well-nourished adult is Triacylglycerol in adipose tissue.

Here's a step-by-step explanation:

1. The human body stores energy in several forms for different purposes. These include glucose in the blood, glycogen in the liver and muscles, and triacylglycerol in adipose tissue.

2. Blood glucose and liver glycogen are readily accessible sources of energy. They can be quickly mobilized to meet immediate energy needs, such as during physical activity or between meals.

3. Muscle glycogen is also a significant energy store, but it is primarily used for local muscle activity and is not readily available for use by other tissues.

4. Triacylglycerol stored in adipose tissue (body fat) represents the largest energy reserve in the body. Unlike the other forms of energy storage, adipose tissue can accumulate virtually unlimited amounts of triacylglycerol, and
