Transcript of GLUTATHIONE

RedOx equation explained by Risha Mariano 3-D
The paper itself
Argument: GSH/GSSG redox potential are dependent on
Nerst Equation is disproven
The GSH/GSSG redox reaction
What is Glutathione??
mother of all antioxidants, the master detoxifier and maestro of the immune system

What are the recent forms of Glutathione?
Redox Regulation by Glutathione needs enzymes
GSH - reduced Glutathione (the absorbable form)
Glutathione (SH-)
attached Sulfur-Hydrogen ion
GSSG - oxidized Glutathione
Glutathione Disulfide
Commercial Purpose?
glutathione inhibits the synthesis and agglutination of melanin
Natural Glutathione
Problem: Reaction is too slow
The goal is to attain EQUILIBRIUM
when can I see the results?
medium brown: 1-3 months

• • dark brown skin: 3-6 months

• • very dark skin: 6-12 months.

• • black skin: at least 2 years or even more

• • Once a person has her desired skin color, the maintenance dose will just be 500mg once a day.

DYK: Oral Glutathione isn't very effective
NADH/ NADP makes the GSH/GSSG attain equilibrium
but it is slow.
when NADH/NAD gets replaced by NADPH/ NADP
also known as GSR
the enzyme to catabolize the NADPH/NADP attainment of equilibrium with the GSH/GSSG couple
a critical molecule in resisting oxidative stress and maintaining the reducing environment of the cell.
Any of a class of organic chemical compounds similar to the alcohols and phenols but containing a sulfur atom in place of the oxygen atom.
What is Glutathione?
needs enzymes to catabolize reaction
how about Vitamin C?
Ascorbate and glutathione play central roles in the defense against free radicals and oxidants that are implicated in chronic diseases.
The Nernst Equation enables the determination of cell potential under non-standard conditions
Application: a hands-on experimental environment is more reliable than a virtual environment even with specific calculations
Redox Regulation by Glutathione needs enzymes

KEYWORDS on the article
- prevents damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides
- a branch of physics concerned with heat and temperature and their relation to energy and work
- is the study of rates of chemical processes.
- are biological molecules (proteins) that act as catalysts and help complex reactions occur
Redox Signaling
- is the concept that electron-transfer processes play a key messenger role in biological systems.
Charles Darwin arguably provides the first illustration ( melanin is a free radical )
