The deficiency leads to decreased activity in the intrinsic pathway (F-IX) factors, monitored by PTT, and the extrinsic pathway (F-VII) which PT monitors. However, factor VII has the shortest half-life of all the factors carboxylated by vitamin K; therefore, when deficient, it is the PT that rises first, since the activated Factor VII is the ...
"Ketoglutaric acid" and "ketoglutarate", when not qualified as α or β, almost always refers respectively to α-ketoglutaric acid or α-ketoglutarate. [2] α-Ketoglutarate is an intermediate in the citric acid cycle, a cycle that supplies the energy to cells. [2] It is also an intermediate in or product of several other metabolic pathways.
Calcium-alpha-ketoglutarate (C 5 H 4 CaO 5 •H 2 O) is a special form mineral calcium that can be used to restore calcium concentration level in the blood back to normal. Calcium-alpha-ketoglutarate binds excess phosphate and pass it as a waste, re-establishing normal balance of calcium and phosphate in the body.
A deficiency in any of the enzymes of this complex as well as an inhibition of the complex as a whole leads to a buildup of branched-chain amino acids and their harmful derivatives in the body. These accumulations lend a sweet smell to bodily excretions (such as ear wax and urine), leading to a pathology known as maple syrup urine disease .

Mutations in isocitrate dehydrogenase (IDH1 and IDH2), which frequently occur in glioma and AML, [1] [2] [3] produce D-2-hydroxyglutarate from alpha-ketoglutarate. [4] D-2-hydroxyglutarate accumulates to very high concentrations which inhibits the function of enzymes that are dependent on alpha-ketoglutarate, including histone lysine demethylases.
α-ketoglutarate + NAD + + CoA → Succinyl CoA + CO 2 + NADH Oxoglutarate dehydrogenase (α-Ketoglutarate dehydrogenase) This reaction proceeds in three steps: decarboxylation of α-ketoglutarate, reduction of NAD + to NADH, and subsequent transfer to CoA, which forms the end product, succinyl CoA. ΔG°' for this reaction is -7.2 kcal mol −1.
The 2013–2014 survey reported that for adults ages 20 years and older, men consumed on average 83.3 mg/d and women 75.1 mg/d. This means that half the women and more than half the men are not consuming the RDA for vitamin C. [21] The same survey stated that about 30% of adults reported they consumed a vitamin C dietary supplement or a multi ...
