Iron Lactate

A spore-forming strain of Desulfitobacterium chlororespirans was able to couple the dechlorination of 3-chloro-4-hydroxybenzoate to the oxidation of lactate to acetate, pyruvate, or formate (Sanford et al. 1996). Whereas 2,4,6-trichlorophenol and 2,4,6-tribro-mophenol supported growth with the production of 4-chlorophenol and 4-bromophenol, neither 2-bromophenol nor 2-iodophenol was able to do so. The membrane-bound dehalogenase contains cobalamin, iron, and acid-labile sulfur, and is apparently specific for ortho-substituted phenols (Krasotkina et al. 2001). 

Pyruvic acid is the simplest homologue of the a-keto acid, whose established procedures for synthesis are the dehydrative decarboxylation of tartaric acid and the hydrolysis of acetyl cyanide. On the other hand, vapor-phase contact oxidation of alkyl lactates to corresponding alkyl pyruvates using V2C - and MoOa-baseds mixed oxide catalysts has also been known [1-4]. Recently we found that pyruvic acid is obtained directly from a vapor-phase oxidative-dehydrogenation of lactic acid over iron phosphate catalysts with a P/Fe atomic ratio of 1.2 at a temperature around 230°C [5]. 

There are fewer data on the frequency of medication use during lactation. Use does appear to be common. A recent Dutch study reported that 53% of all breast-feeding mothers had taken a medication, herb, or supplement (exclusive of iron, vitamins, and homeopathic remedies).5 Furthermore, more women in the United States are now abiding by the recommendation to breast-feed. It is now estimated that up to 50% of United States women breast-feed for at least a short time.6...

MnP is the most commonly widespread of the class II peroxidases [72, 73], It catalyzes a PLC -dependent oxidation of Mn2+ to Mn3+. The catalytic cycle is initiated by binding of H2O2 or an organic peroxide to the native ferric enzyme and formation of an iron-peroxide complex the Mn3+ ions finally produced after subsequent electron transfers are stabilized via chelation with organic acids like oxalate, malonate, malate, tartrate or lactate [74], The chelates of Mn3+ with carboxylic acids cause one-electron oxidation of various substrates thus, chelates and carboxylic acids can react with each other to form alkyl radicals, which after several reactions result in the production of other radicals. These final radicals are the source of autocataly tic ally produced peroxides and are used by MnP in the absence of H2O2. The versatile oxidative capacity of MnP is apparently due to the chelated Mn3+ ions, which act as diffusible redox-mediator and attacking, non-specifically, phenolic compounds such as biopolymers, milled wood, humic substances and several xenobiotics [72, 75, 76]. 

Exudation occurs in response to environmental constraints, especially P deficiency (e.g., Jones 1998 Hinsinger et al. 2003) and differs depending on the P-form (Lambers et al. 2002) and plant species (Nuruzzaman et al. 2006). Banksia grandis exuded citrate, malate, and trans-aconitate when supplied with aluminium-phosphate. It exuded less of these tricarboxylates and dicarboxylates, but instead lactate and acetate, when supplied with iron-phosphate (Lambers et al. 2002). Plant species differ in their abilities to use various P species (van Ray and van Diest 1979), which can be due to differences in their exudation behavior (Nuruzzaman et al. 2006) and acidification of the root zone (Haynes 1992). This can influence the interspecific competition and coexistence of species, as we will discuss later. 

Calcium Lactate Dissolve 0.5 g in DW add 2 ml of a 20% w/v soln. of iron-free-citric acid and 0.1 ml of thioglycollic acid, mix, make alkaline with iron-free-ammo-nia soln., dilute to 50 ml with DW and allow to stand for 5 minutes. Any colour produced is not more intense than that obtained by treating in the same manner 2.0 ml of iron standard solution (20 ppm Fe) in place of the soln. being examined.

For the second level, the correction of modest iron deficiency, various iron salts have been recommended or prescribed as iron supplements. These salts have included iron(II) succinate, fumarate, gluconate, and lactate, and iron(III) citrate - or, better (335), ammonium iron(III) citrate as iron(III) citrate seems to be a poorly characterized compound (337). There are two main problems. The first is the ease of oxidation of the iron(II) salts, particularly the lactate. The second is that absorption of iron from these sources is very inefficient (57), as species such as Fe (aq), Fe (aq), and simple hydrolysed entities such as FeOH (aq) cross membranes such as those that constitute the wall of... 

Wielinga et al. (2001) demonstrated this process by incubating goethite anaerobically at pH 7 with lactate and an iron-reducing bacterium, and introducing Cr(VI) after commencement of Fe(III) reduction (Figure 7.7). In treatments without Cr(VI), accumulation of Fe(II) in solution continued, but in the treatments with Cr(VI) it was reversed in abiotic controls there was no accumulation of Fe(II). Chromate can also be reduced abiotically by sulfide.

In most adults with anemia 100 mg elemental iron per day usually produces an adequate response. Iron supplementation in prophylactic doses of 60 mg of elemental iron daily may be justified, e.g. in pregnancy and lactation. 

Nutritional iron deficiency anaemia other causes in which iron deficiency can occur are pregnancy, lactation, infants, children. In patients with malabsorption syndrome, patients who are taking NSAIDs for long period, patients with chronic inflammatory disease and in patients of gastrectomy.

Normally, the sum of the cations exceeds the sum of the anions by no more than 12-16 mEq/L (or 8-12 mEq/L if the formula used for estimating the anion gap omits the potassium level). A larger-than expected anion gap is caused by the presence of unmeasured anions (lactate, etc) accompanying metabolic acidosis. This may occur with numerous conditions, such as diabetic ketoacidosis, renal failure, or shock-induced lactic acidosis. Drugs that may induce an elevated anion gap metabolic acidosis (Table 58-1) include aspirin, metformin, methanol, ethylene glycol, isoniazid, and iron.
