Dipicolinic acid (Pyridine-2,6-dicarboxylic acid, DPA) is known to chelate a wide variety of multivalent metal ions, including Ca(II), Mg(II), Cu(II), Ni(II), Zn(II), Co(II), Tb(III), U(IV), and Mn(II) ions. I will elaborate on some of the biochemical aspects of DPA. DPA is structurally related to other pyridine carboxylic acids like nicotinic acid (vitamin B3). These related compounds are found in the metabolic pathways of animals and are utilized for the transport and scavenging of metal ions by the body. Approximately 15% (w/w) of the material composing Bacillus spores is DPA; a very large concentration for a cell to express. One might ask, 'Why should so much energy be utilized in the production of extraordinary concentrations of DPA?'. It has been determined with certainty that large DPA-Ca(II) complexes are responsible for the high thermal and UV stability of Bacillus spores. Particularly, the role in defense against damage to nucleic acids (DNA) has been reported [Journal of Bacteriology, June 2006, p. 3740-3747, Vol. 188, No. 11]. Thus, survival of the spores is dependent on the production of vast quanities of DPA, reenforcing the optimization of DPA signalling pathways for these species.

Chemical analysis of a bacterial cell structure detects calcium dipicolinic acid What is the identity of this structure?
The bacterial cell structure containing calcium dipicolinic acid is likely a spore, specifically an endospore. Endospores are highly resistant, dormant structures formed by certain bacteria as a means of surviving harsh environmental conditions. The presence of calcium dipicolinic acid helps stabilize the spore structure and contributes to its resistance properties.
What is Calcium Amino Acid Chelate?
Calcium Carbonate/Oxide + Amino Acid = Calcium Amino Acid Chelate The reaction should be carried at 80 degree C. Make the amino acid content always double to metal content to get better chelation.
What is Chromium Amino Acid Chelate used for?
Chromium amino acid chelate is used as a dietary supplement to support glucose metabolism and insulin sensitivity. It may help improve blood sugar levels in people with type 2 diabetes or prediabetes, and also plays a role in macronutrient metabolism.
What chelate is formed by lead and dithiozone?
neutral yellow coloured chelate
Is there a difference between manganese chelate and magnesium chelate?
Yes, there is a difference between manganese chelate and magnesium chelate. Manganese chelate contains manganese, an essential mineral that supports various bodily functions, while magnesium chelate contains magnesium, another essential mineral that is crucial for nerve and muscle function, among other roles in the body. Both minerals are typically chelated for better absorption in supplement form.
What is magnesium chelate?
Magnesium chelate refers to a type of magnesium supplement where the mineral is bound to an amino acid for better absorption in the body. This form of magnesium is often used to help support various bodily functions, such as muscle and nerve function, energy production, and bone health.
How many legs are chelate on a crayfish?
None. They use their pedipalps for sensory.
Why does a bacterial spore not die when it is cooked?
Bacterial spores have a tough protective coat that shields them from extreme conditions like heat. When food is cooked, the spores may not be destroyed as they can withstand high temperatures. These spores can later germinate into bacteria if the conditions are favorable.
Is EDTA is water soluble?
Yes, EDTA (Ethylenediaminetetraacetic acid) is water soluble. It forms stable complexes with metal ions in water due to its ability to chelate metal ions.
What has the author Larry Allen Dressel written?
Larry Allen Dressel has written: 'The sterochemistry of the mixed colbalt (III) chelate complexes with 4-R-Diethylene-Triamine and Beta-Methyl-aspartic acid, where R is a hydrogen or methyl group' -- subject(s): Spectra, Aspartic acid, Cobalt
What is a central metal chlorophyll natural occurring chelate compound?
magnesium
What would represent a source of possible iron contamination?
