Glycine (symbol Gly or G; [6] / ˈ ɡ l aɪ s iː n / ⓘ) [7] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid ( carbamic acid is unstable). Glycine is one of the proteinogenic amino acids .

Glycine methyl ester hydrochloride can be prepared by treatment of glycine with 2 equivalents of trimethylsilyl chloride, followed by the addition of methanol. [2] [3]Upon treatment with base, the salt converts to glycine methyl ester.
In this reaction, glycine is treated with aqueous formaldehyde in formic acid that serves as both solvent and reductant. Hydrochloric acid is added thereafter to give the hydrochloride salt. The free amino acid may have been obtained by neutralization of the acid salt, which has been performed with silver oxide. [6]
The more salt added, the greater the effect on the freezing point. So, if it is 28 degrees Fahrenheit outside, adding extra salt might not be needed as much as if, say, it was 20 degrees out.
Boiling-point elevation is the phenomenon whereby the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.
