Selenohomocystine_[M+Na]+ (BioDeep_00000227955)
2-amino-4-[(3-amino-3-carboxypropyl)diselanyl]butanoic acid

SMILES: [Se](CC[C@H](C(=O)O)N)[Se]CC[C@H](C(=O)O)N

Selenohomocystine is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Selenohomocystine is soluble (in water) and an extremely strong acidic compound (based on its pKa). Selenohomocystine can be found in garden onion, which makes selenohomocystine a potential biomarker for the consumption of this food product.
