Arginine (likely intended, as "Argentinine" appears to be a misspelling) plays a key role in several physiological processes, making it valuable in medical, nutritional, and pharmaceutical applications. It is commonly used to support cardiovascular health by promoting blood flow through its role in nitric oxide production, which helps blood vessels relax and dilate. This property is beneficial in managing conditions like hypertension and angina.

In clinical settings, arginine is added to parenteral nutrition formulas to support protein synthesis and wound healing, especially in post-surgical or critically ill patients. It also stimulates the release of growth hormone and insulin, which contributes to its use in metabolic and endocrine assessments.

Athletes and fitness supplements often include arginine to enhance exercise performance and muscle recovery due to its ability to improve circulation and reduce fatigue. Additionally, it supports immune function and has been studied for its potential in improving erectile dysfunction and supporting male fertility.

In research and biotechnology, arginine is used in protein stabilization and as a component in cell culture media to support cell growth and expression of recombinant proteins.
