Post-squalene sterol synthesis
WebThe fatty acids in pumpkin seeds contain a rangeTrusted Source of beneficial nutrients, such as sterols, squalene, and tocopherols. Researchers have described the fatty acid profile of seeds, grains, and legumes as “favorable.” Bone health Pumpkin seeds are a good source of magnesium, which is important for bone formation. WebIn the subsequent steps of the pathway, six molecules of isopentenyl-pyrophosphate are used for the synthesis of one cholesterol molecule. Formation of a C 10 intermediate Squalene cyclization yields the first sterol intermediate. The reactions shown here are catalyzed by squalene epoxidase and lanosterol synthase.
