Let’s explore “DHEA-S”

GSTO1 belongs to the omega family of glutathione S-transferases. These enzymes participate in redox chemistry, with roles that differ from the better-known GSTM1 and GSTP1 pathways.

PSEN1 encodes a presenilin protein that participates in gamma-secretase, a protein-processing complex. Some pathogenic variants can cause familial Alzheimer’s disease; a listed common marker is not equivalent to that diagnosis.

PSEN2 encodes a presenilin protein that participates in gamma-secretase, a protein-processing complex. Some pathogenic variants can cause familial Alzheimer’s disease; a listed common marker is not equivalent to that diagnosis.

SOD1 helps convert superoxide inside cells as part of the body’s antioxidant defenses.

SOD2 works in mitochondria as part of the body’s antioxidant defenses.

SOD3 works outside cells as part of the body’s antioxidant defenses.

GSTO2 encodes glutathione S-transferase omega 2, a redox enzyme with dehydroascorbate reductase activity that connects glutathione chemistry with vitamin C recycling. It is a separate gene from GSTO1.

Everyone is talking about collagen, protein, and vitamins. Almost no one is talking about one of your body's most important antioxidant defenses. Superoxide dismutase (SOD) is a naturally occurring enzyme that helps your body neutralize o
