C6H14N4O2

C6H14N4O2 is the molecular formula for the amino acid L-Arginine. Arginine is an α-amino acid with the chemical name 2-amino-5-(diaminomethylideneamino)pentanoic acid. It is considered a semi-essential or conditionally essential amino acid, meaning that while the human body can usually synthesize it, supplementation may be required under certain conditions, such as periods of rapid growth, illness, or injury.

Arginine contains an α-amino group, an α-carboxylic acid group, and a guanidino group as a side chain. The guanidino group makes arginine a highly basic amino acid. At physiological pH, the guanidino group is protonated, giving arginine a positive charge.

Arginine plays several crucial roles in human physiology. It is a precursor for the synthesis of nitric oxide (NO), a signaling molecule involved in vasodilation, neurotransmission, and immune function. It is also involved in the urea cycle, a metabolic pathway that removes ammonia from the body. Furthermore, arginine contributes to protein synthesis and is involved in wound healing.

Dietary sources of arginine include meats, poultry, fish, dairy products, nuts, and seeds. Arginine supplements are also available, often marketed for their purported benefits in improving athletic performance, cardiovascular health, and immune function. However, the efficacy of arginine supplementation for these purposes is still under investigation and may vary depending on the individual and the specific condition being addressed.

Due to its involvement in several metabolic pathways, arginine deficiency or excess can have significant physiological consequences. Arginine deficiencies may lead to impaired immune function, delayed wound healing, and reduced nitric oxide production. High levels of arginine can potentially exacerbate certain medical conditions, and interactions with other medications are possible.
