Chemical Properties

white crystalline powder

Uses

2-amino-4-sulfobutanoic acid is an alanine derivative[1].

Definition

ChEBI: Homocysteic acid is a non-proteinogenic alpha-amino acid that is homocysteine in which the thiol group has benn oxidised to the corresponding sulfonic acid. It is an amino sulfonic acid, a carboxyalkanesulfonic acid and a non-proteinogenic alpha-amino acid. It is functionally related to a homocysteine.

General Description

Complexes of DL-homocysteic acid with Na⁺, Cu²⁺, Zn²⁺ and Ni²⁺ has been synthesized. DL-Homocysteic acid induces oxidative stress in brain of immature rats.
