The herbicide glyphosate is similar to glycine, an amino acid
The herbicide glyphosate was originally patented as an antibiotic and as a mineral chelator (a protein that can bind and transport minerals). It has been in use as an agricultural herbicide since 1975. However it's use greatly increased in the last ten years since genetically modified Round-Up Ready crops were developed. A professor from Massachusetts Institute of Technology has been researching glyphosate and it's possible role in the development of autism.
Professor Seneff gave two presentations at an Autism One conference earlier this year. The PowerPoint slides to the lectures are available in links included in the Tweets below, click these links for the pdfs to each video: people.csail.mit.edu/seneff/2016...
The first video includes more information about the chemical similarity between glyphosate and glycine. Glycine is an amino acid that provides methyl groups. Glyphosate is very similarly shaped but has an extra side chain and it wouldn't provide methyl groups. It is possibly similarly shaped enough, however, for glyphosate to be incorporated into the structure of proteins instead of glycine. It would be like a puzzle piece that fits into another piece but won't allow any other pieces to be added. Glyphosate may fit in glycine's spot within a protein but then wouldn't provide any methyl groups and the extra side chain could interfere with receptor function - like having an extension cord with prongs that no longer can fit into an electric socket because the socket is already blocked with something else.
The risk to health if this is true could be significant. Many proteins contain glycine and any one of them might be important in a variety of ways which glyphosate could disrupt. This is in very early stages of research but the impact could also affect vaccinations because the collagen used to culture material for vaccinations could contain glyphosate instead of glycine if the animals from which the collagen was obtained had been raised with feed containing glyphosate residue.
Zika virus that grew in an environment that contained glyphosate might have it incorporated into proteins instead of glycine which could be making the disease far more dangerous prenatally than it had been in past decades before glyphosate became widely used. Zika infections had not been associated with microcephaly until recently. The second video goes into more detail about how glyphosate could be making Zika more dangerous.

I will get back to this topic after rewatching the videos and taking notes on the recommendations she makes about food and lifestyle strategies for reducing glyphosate exposure or reducing glyphosate levels that may be stored within the body.
