Nutrition Facts: Amino acids are the building blocks of protein. Protein has an important job in building and rebuilding body tissue and providing the body with nitrogen, an essential element for all living beings. There are both essential and nonessential amino acids. Essential amino acids must be obtained from the diet; nonessential amino acids are made by the body. Here are lists of the essential and nonessential amino acids:

1. What is the difference between D- and L-Phenylalanine? The D- and L- refer to the 3-D configuration of the amino acid. Only one of these isomers, the L-form, is used by the body for constructing its proteins. However, in the body certain reactions can convert the D- form into the L- form thereby allowing it to be used for protein synthesis. In humans, only D- phenylalanine and D-methionine can be converted to their L-isomers and be available for the body to use in protein synthesis.

2. What makes the nonvegetarian amino acids so? Some of our amino acids are not classified as vegetarian because the amino acid may be isolated from a protein of animal origin. For example, Complete Amino (VL955) contains a protein hydrolysate from a milk protein, and would not be appropriate for a vegan, but would be appropriate for a lactovegetarian.
