Final answer:
Glutamine is the non-essential amino acid most famous for its role in stimulating human growth hormone. It enhances amino acid uptake by cells and promotes protein synthesis and body growth.
Step-by-step explanation:
The non-essential amino acid most famous for its role in the stimulation of human growth hormone is glutamine. Glutamine is an important nutrient for the growth and maintenance of muscles, and it plays a key role in stimulating the release of human growth hormone (GH) from the anterior pituitary gland.
GH promotes protein synthesis and body growth, and glutamine enhances this process by enhancing amino acid uptake by the cells. Glutamine also helps in the retention of phosphorus, potassium, sodium, and calcium.
