Linked from

The 36 pages that link to Nitric oxide, each with the reason it gives.

• Carbon monoxideCompared with: It is another small gaseous molecule that binds heme, but it has distinct biological roles.

• Nitrous oxideCompared with: Nitric oxide and nitrous oxide have different formulas, biological roles, and atmospheric behavior.

• VasoconstrictionCompared with: It opposes constriction by promoting vessel relaxation.

• VasodilationRelated: It is a major signal that triggers vasodilation.

• PeristalsisRelated: Enteric neurons use it to relax gut muscle ahead of a moving bolus.

• EndotheliumRelated: Endothelial cells release it to promote vessel relaxation and limit platelet adhesion.

• Erectile dysfunctionRelated: It initiates the vascular relaxation needed for penile blood filling.

• Nitrogen oxidesBroader topic: It is emitted directly and rapidly reacts with oxygen to form nitrogen dioxide.

• Endothelial dysfunctionRelated: Reduced endothelial nitric oxide availability is a central cause of impaired vessel relaxation.

• Nitrogen dioxideRelated: This rapid atmospheric reaction is a major route from combustion emissions to NO₂.

• EicosanoidCompared with: It shares local vascular effects with eicosanoids despite having a chemically distinct origin.

• Vascular smooth muscleRelated: Endothelial nitric oxide activates pathways that reduce smooth-muscle contraction.

• NitriteRelated: Nitrite-derived nitric oxide binds myoglobin, producing the pigment that gives cured meat its pink color.

• Sodium nitriteRelated: Nitrite can serve as a source of nitric oxide in tissues and during meat curing.

• PenisRelated: Nerve-released nitric oxide helps increase penile blood flow during erection.

• Nitrous acidRelated: It is one product of nitrous acid disproportionation.

• Ostwald processRelated: It is the immediate nitrogen-containing product of ammonia oxidation.

• Diatomic moleculeBroader topic: NO is a heteronuclear diatomic molecule and a biologically active free radical.

• NitrosationRelated: Its oxidation and related reactions can supply nitrosating equivalents.

• ArterioleRelated: Endothelial nitric oxide promotes arteriolar dilation.

• Nitric oxide synthaseBroader topic: This short-lived signaling molecule is the enzyme family's principal product.

• AchalasiaRelated: Loss of nitric-oxide-producing inhibitory neurons impairs sphincter relaxation.

• SuperoxideRelated: It reacts rapidly with superoxide to form peroxynitrite.

• ErectionRelated: Nerve-released nitric oxide starts the smooth-muscle relaxation that increases penile blood flow.

• Law of multiple proportionsBroader topic: Compared with nitrogen dioxide, it provides a second example of changing oxygen mass ratios.

• Second messenger systemRelated: It initiates cyclic GMP signaling without requiring a cell-surface receptor.

• BeetrootRelated: Dietary nitrate from beetroot can be converted into nitric oxide.

• CitrullineBroader topic: Its production is the proposed pathway behind several cardiovascular claims for citrulline.

• Dinitrogen tetroxideCompared with: Unlike N₂O₄, it is a monomeric radical rather than a dimeric reservoir of NO₂.

• Nitrosyl chlorideRelated: It combines with chlorine to form nitrosyl chloride.

• VardenafilRelated: Sexual stimulation triggers nitric-oxide signaling, which vardenafil amplifies indirectly.

• Amyl nitriteRelated: Amyl nitrite releases nitric oxide, which drives its rapid vascular relaxation.

• Dinitrogen trioxideRelated: It combines with nitrogen dioxide to form N₂O₃ and reappears when N₂O₃ dissociates.

• Pentaerythritol tetranitrateRelated: In the body, PETN promotes nitric oxide signaling, widening blood vessels.

• Human penisRelated: In erectile tissue, it initiates smooth-muscle relaxation that increases blood flow.

• HydroxycarbamideRelated: Hydroxycarbamide may promote nitric oxide signaling, another proposed contributor to its effects in sickle cell disease.
