What is HYPOTAURINE?

The Uses of HYPOTAURINE

Hypotaurine is a metabolite of taurine and affects the regulation of the inflammatory aspects of the immune response. It is also converted into taurine in the body.

The Uses of HYPOTAURINE

Hypotaurine has been used as a supplement in fertilization medium (Fert- tyrode albumin lactate pyruvate (TALP)), which used in in-vitro fertilization and evaluation of embryo development. It is also used as a H₂S scavenger.

What are the applications of Application

Hypotaurine is an endogenous inhibitory signaling amino acid

Definition

ChEBI: Hypotaurine is an aminosulfinic acid comprising ethylamine having the sulfo group at the 2-position. It has a role as a metabolite, a human metabolite and a mouse metabolite. It is a conjugate acid of a hypotaurine(1-). It is a tautomer of a hypotaurine zwitterion.

Biological Activity

Endogenous inhibitory amino acid.

Biochem/physiol Actions

Hypotaurine, a cystamine analog, is the precursor for taurine synthesis. It can act as an antioxidant and singlet oxygen scavenger, thereby protecting cells from oxidative damage. Hypotaurine is reported to play an important role in the maintenance and stimulation of sperm motility and also in vitro fertilization and embryo development.
