Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| text | In a healthy, well-nourished individual, the production of ketone bodies occurs at a relatively low rate. During periods of normal physiological responses to carbohydrate shortages, the liver increases the production of ketone bodies from acetyl-CoA generated from fatty acid oxidation. This allows heart and skeletal muscle to use ketone bodies as the primary source of energy, thereby preserving the limited glucose supply for use in brain tissue. In untreated diabetes mellitus, a huge buildup of ketone bodies occurs due to an increase in fatty acid oxidation. The production of ketone bodies exceeds the ability of peripheral tissues to oxidize them, and results in lowering the pH of blood. Blood acidification is dangerous, chiefly as it impairs the ability of hemoglobin to bind oxygen. Ketone body synthesis proceeds via the synthesis of ccetoacetic acid in three steps from acetyl CoA, followed by the reduction of acetoacetic acid to beta-hydroxybutyrate. In the body, these reactions occur in the mitochondria of liver cells (Sass 2011). |
