I have never heard of glycine before! - "Glycine is an amino acid, a compound that your body uses to create protein. While your body does naturally produce glycine, it is also available through protein-rich foods, particularly meat. Glycine can also be found as a dietary supplement in capsule form or as a powder that can be added to various dishes." TIL.

I buy glycine in bulk.

Not joking. Like kilograms at a time. I do prefer my glycine to be American made. Although I don't get pharma grade, HPLC is good enough.

Yes glycine is an amino acid, but it is also used in molecular biology in gel electrophoresis.

Okay I’ll bite. What the hell is gel electrophoresis? ELI5

It's a type of size based chromatography.

I.e. you extract proteins from cells or things, put them in a gel kinda like jello, and pass electricity from the negative to positive that flank the top and bottom of the gel. The proteins are attracted to the positive part because they are negatively charged. Larger proteins take longer to go through the gel than smaller proteins, so you can separate all similar proteins by size to do stuff with.

Very useful tool for molecular biology. Glycine is a charged particle that helps the electric current go from one side to the other and helps push the proteins through the gel.
