Phtalates heavy metals pregnancy

Copper is a heavy metal and is needed for myelin development. [1-3] Surely too much of a good thing is bad. Often other heavy metals follow copper. A study out of Rhode Island USA correlated neurological health with placental heavy metal concentration. [4] A study out of Taiwan looked at heavy metals and phtalates in the urine of pregnant mothers. [5] Both studies correlated heavy metals with mental functioning of the children. Phtalates are used in the production of plastics. When an expecting mother has concerns about heavy metals in the town’s water supply she drinks more bottled water right? This post makes a weak attempt to explain the statistics used in the Rhode Island and Taiwan studies. The take home is that prenatal copper is likely a good thing. Phthalates are probably bad. You really need to discuss the issue with someone licensed to practice medicine.

Oleuropein

We at CopperOne have been telling customers to add cuprous niacin to an oil to keep it in the +1 oxidation state. Why not olive oil? Oleuropein is “the most important phenolic compound present in olive cultivars. It has a role as a plant metabolite, a radical scavenger, an anti-inflammatory agent, an antineoplastic agent, an antihypertensive agent, a NF-kappaB inhibitor, an apoptosis inducer, an antioxidant and a nutraceutical.”

Sp1 and copper

This post investigates a claim in a review by Morrel and coworkers that excessive dietary fructose can decrease the expression of Ctr1 in the duodenum. [1] How could this happen? What is transcription factor for Ctr1? As it turns out, both Cu+ and Cu2+ can bind to the CTR1 transcription factor Sp1 and negatively regulate its activity [2,3] The featured image describes out Cu can disrupt the Zn2+ finger(s?) Sp1 uses to bind to the promoters of itself and CTR1. If you wish to skip the details of some brilliant experiments, click to go to the lay friendly summary.

Copper Chaperones

Starting from Ctr1 Let us continue the journey from Ctr1 to some intracellular copper chaperones.  The cyoplasmic loops might have their own gating functions, as suggested by Ren (2019), see Ctr1 post Just looking at the sequences, there are a lot of arginines (R) and lysines (K) Fig 1C). Both of these are positively chargedContinue reading “Copper Chaperones”
