Glutamic Acid Movies

Glutamic Acid Video No. 1 - Glutamic acid crystallization is observed under polarized light illumination at a magnification of 10x in this video. Playing time is 8.9 seconds. Choose a playback format that matches your connection speed: 28.8k (modem), 56.6k (modem), or T1/Cable/DSL, or download this video clip in MPEG format (3.70 MB).

Glutamic acid is biosynthesized from a number of amino acids including ornithine and arginine. When aminated, glutamic acid forms the important amino acid glutamine. Because it has a carboxylic acid moiety on the side chain, glutamic acid is one of only two amino acids (the other being aspartic acid) that has a net negative charge at physiological pH.
