Added chelation in plants and micro-organisms. Chemists should dig up references for the other bits. Miikka Raninen 19:38, 27 November 2005 (UTC)
[edit] Sequestering same as chelating?
I believe so, so I'm adding it. --Rajah 01:19, 9 July 2006 (UTC)
[edit] Merging with Chelate effect
I support the merger (hardly anything links here anyway). --Dirk Beetstra T C 22:53, 17 July 2006 (UTC)
- Yeah, I think someone was working on missing articles, but didn't search hard enough to realize this one wasn't missing after all. —Keenan Pepper 22:58, 17 July 2006 (UTC)
I also think they should be merged.
-rshigeta
I agree. The merge seems sensible. -mc043
- Agree, merge. Dieter Simon 00:05, 16 August 2006 (UTC)
OOps .. forgot to tell, I already merged all the articles together (chelate effect, chelation, chelant, etc). All is now 'here'. --Dirk Beetstra T C 07:07, 16 August 2006 (UTC)
Important addition to the definition: it should emphasize that a single bond does not form a chelate -- this term is generally reserved for two or more bonds, of any type, between the chelating agent and the metal ion. Axewiki 15:05, 28 September 2006 (UTC)
[edit] section 'uses - nutrition' seems very non-factual
Right now,it says this:
In nutrition, certain amino acids are utilized as chelating agents to replicate the natural mineral forms found in raw fruits, vegetables, and grains. The resultant chelated minerals are absorbed directly into the bloodstream through the intestinal villi in relatively high proportions. Because micromineral levels in farm soils tend to gradually decline over the years, and because modern food processing often breaks the chelate bond and renders any remaining minerals much less bioavailable, humans today receive reduced quantities of minerals from their meals[verification needed]. Dozens of medical studies have shown that dietary supplementation with both vitamins and chelated minerals can have wide-ranging benefits to health, mental acuity, and life expectancy[verification needed]. Chelated minerals are sometimes prescribed by doctors to treat such ailments as anemia, arthritis, diabetes, nervous disorders, and heart attacks[verification needed].
Fortunately it already says 'verification needed' but the whole section is less-than-factual in tone.
micromineral levels in farm soils tend to gradually decline over the years - this is what soil fertilizer is for, right? (non-nutrition sidenote: There's a serious environmental issue with overmineralization of soil, due to excess supply with dung from intensive farming. This lead to obligatory registration, for farms in Europe, of their total mineral input and output.)
modern food processing often breaks the chelate bond - I actually came to this article after reading some concerns about artificial chelate agents such as EDTA being used as additives!! Seems there's very opposing concerns.
humans today receive reduced quantities of minerals from their meals - source badly needed.
Dozens of medical studies have shown - - source badly needed. wording very non-factual
The nutritional claims should IMHO refer to the wiki article on Dietary mineral. Whether the minerals used in mineral supplements are usually administered in the form of chelates,is relevant but needs verification.
Chelated minerals are sometimes prescribed by doctors - it is important to note that Chelation Therapy , (linked in 'see also') , is actually about administering chelating agents to remove excess minerals, not about medical use of chelated minerals. Is there any source or article supporting these medical claims on the use of chelated minerals, other than anything being said in Dietary mineral ?
