D. The secretion of gastric glands does not have lipases

Answer

To determine which statement is not true about the stomach in humans, let's analyze each option one by one.

1. **Esophagus opens in the cardiac part of the stomach.**
- The esophagus connects to the stomach at the cardiac part (also known as the cardia). This statement is true.

2. **Pepsin is the proteolytic enzyme of the stomach.**
- Pepsin is indeed a proteolytic enzyme that is active in the stomach and aids in the digestion of proteins. This statement is also true.

3. **Renin is a proteolytic enzyme in gastric juice of infants.**
- Renin (or rennin) is an enzyme that helps in the digestion of milk proteins in infants. This statement is true as well.

4. **The secretion of gastric glands does not have lipases.**
- This statement is incorrect. The gastric juice does contain a small amount of gastric lipase, which is involved in fat digestion. Therefore, this statement is not true.

Based on the analysis, the statement that is not true about the stomach in humans is the fourth option.

### Final Answer:
The correct answer is: **The secretion of gastric glands does not have lipases.**
