Aspartic acid, also known as , is a non-essential amino acid that serves as a vital metabolic hub within the human body . While it is often simplified as a basic protein building block, its actual biological utility spans from energy production to neuroendocrine regulation and industrial manufacturing. Biological Roles and Forms
Its derivative, polyaspartic acid, is used as a biodegradable fertilizer enhancer to improve crop yields and nitrogen absorption.
The most common form, L-Asp is a "proteinogenic" amino acid used to build enzymes and tissues. It is central to the urea cycle , helping the liver detoxify ammonia, and plays a key role in the malate-aspartate shuttle , which helps cells generate energy (ATP).
High doses of single amino acid supplements can cause a negative nitrogen balance , potentially straining the kidneys. Supplementation is generally discouraged for pregnant women and children due to possible impacts on brain development. What is Aspartic Acid? - News-Medical.Net
