Common Name | Selenocysteine |

Description | Selenocysteine, also known as 3-seleno-alanine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Selenocysteine is a very strong basic compound (based on its pKa). Selenocysteine exists in all living species, ranging from bacteria to humans. Within humans, selenocysteine participates in a number of enzymatic reactions. In particular, selenocysteine can be converted into L-alanine and hydrogen selenide; which is catalyzed by the enzyme selenocysteine lyase. In addition, selenocysteine and 2-ketobutyric acid can be biosynthesized from selenocystathionine through the action of the enzyme cystathionine gamma-lyase. In humans, selenocysteine is involved in selenoamino acid metabolism. The L-enantiomer of selenocysteine. Selenocysteine is expected to be in Cannabis as all living plants are known to produce and metabolize it. |
