Similarly, the structure of proteins can be altered by changing the protonation state of amino-acid residues. As a consequence, the pH in biochemical systems is carefully buffered to be maintained at particular values as fluctuations in pH would have large consequences on protein structure and function.

Aspartic acid (also called "aspartate") is a naturally occuring amino acid which is a component of all proteins. It is classified as a "non-essential" amino acid, meaning that humans do not need to get it from their diets since they can make it from other things in the diet.

This gives aspartic acid an overall negative charge at physiological hydrogen ion concentrations (approximately pH 7.3). Although aspartic acid is considered a non-essential amino acid, it plays a paramount role in metabolism during construction of other amino acids and biochemicals in the citric acid cycle. Oct 14, 2019 · Aspartic acid, or d-aspartic acid, is a non-essential amino acid. This means that your body produces an adequate amount of it without a need to supplement or get the amino acid from food sources.
