… in the conversion of homocysteine to methionine.
Also called: Methionine Synthase
The B12-dependent step
In Dr. Purser’s teaching map, MTR is the B12-dependent step that converts homocysteine back to methionine. This helps explain why a me…
…n the activity of methionine synthase, connecting B12-related chemistry with homocysteine metabolism.
Also called: Methionine Synthase Reductase
Keeping the remethylation system working
Dr. Purser teaches MTRR alongside MTR because the path…
NAT2 encodes N-acetyltransferase 2, which helps process certain drugs and other compounds. Combinations of variants can influence acetylation status; one SNP usually does not tell the entire story.
Also called: N-Acetyltransferase 2
Acetyla…
NOS3 encodes endothelial nitric oxide synthase, which helps blood vessels generate nitric oxide, a signal involved in vascular relaxation. This pathway is distinct from a blood pressure measurement or a diagnosis of vascular disease.

NQO1 is the gene symbol used for NAD(P)H Quinone Oxidoreductase 1. This page connects its terminology with the topics in the Purser Wellness teaching library.
Also called: NAD(P)H Quinone Oxidoreductase 1
Quinone handling within the redox n…
NR3C1 encodes the glucocorticoid receptor, which helps tissues respond to cortisol and glucocorticoid medicines. Receptor genetics and measured cortisol levels answer different questions.
Also called: Nuclear Receptor Subfamily 3 Group C Me…
NR3C2 encodes the mineralocorticoid receptor, which responds to hormones such as aldosterone and helps regulate salt and fluid balance. It is distinct from the NR3C1 glucocorticoid receptor.
Also called: Mineralocorticoid Receptor / Nuclear…
NTRK2 encodes TrkB, a receptor involved in responding to neurotrophic signals such as BDNF. These signals support nervous-system function and plasticity. NTRK2 is not a phosphatidylserine absorption transporter.
Also called: Neurotrophic Re…
Makes an enzyme involved in producing phosphatidylcholine, a component of cell membranes. Genetic findings alone do not establish a choline deficiency.
Also called: Phosphatidylethanolamine N-Methyltransferase, choline, phosphatidylcholine

PON1 appears in Dr.
Also called: Paraoxonase 1
A different part of antioxidant handling
PON1 appears in Dr. Purser’s redox and conversion teaching alongside GST and NQO1. The genetics reference discusses it in relation to handling particula…
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.

Best match puts all-term matches before partial matches and related reading. Identical social posts and matching long titles across other sources are grouped when access is the same. Search covers published titles, descriptions, available article text, report overviews, and the full text of the nutrient, gene and learning-essential reference pages. Books, uploaded chapters and downloads-page reports are searchable through selected editorial guides and topic names; the original files and full book text are not published. Full Drive reports are not copied into search. Substack subscriber titles and public summaries are included; full subscriber content opens on Substack. Video transcripts are added when available.
