Main glucocorticoid hormone responsible for carbohydrate metabolism is

Answer

**Step-by-Step Solution:**

1. **Identify the Type of Hormone**: The question specifies that we are looking for a glucocorticoid hormone. Glucocorticoids are a class of steroid hormones produced by the adrenal cortex.

2. **Understand the Role of Glucocorticoids**: Glucocorticoids play a significant role in various metabolic processes, including carbohydrate metabolism. They help regulate blood glucose levels and are involved in the metabolism of proteins and fats.

3. **Differentiate from Other Hormones**: It is important to note that while insulin and glucagon are also involved in carbohydrate metabolism, they are peptide hormones, not glucocorticoids. The question specifically asks for a glucocorticoid.

4. **Identify the Main Glucocorticoid**: The primary glucocorticoid hormone responsible for carbohydrate metabolism is cortisol. It is secreted by the adrenal cortex, specifically from the zona fasciculata layer.

5. **Understand the Function of Cortisol**: Cortisol is released in response to stress and low blood glucose levels. It stimulates gluconeogenesis, which is the formation of glucose from non-carbohydrate sources, thereby increasing blood glucose levels.

6. **Conclude the Answer**: Based on the information gathered, we can conclude that the main glucocorticoid hormone responsible for carbohydrate metabolism is cortisol.

**Final Answer**: The main glucocorticoid hormone responsible for carbohydrate metabolism is cortisol.
