Glycerol (/ ˈɡlɪsərɒl /) [6] is a simple triol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in lipids known as glycerides. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations.
But you see the tell-tale signs, you see a glycerol backbone right over here and three fatty acids, or what were three fatty acids attached to what was a glycerol molecule. We go into a lot of depth on that.
3 Απρ 2008 · Glycerol is used in medical and pharmaceutical preparations, mainly as a means of improving smoothness, providing lubrication and as a humectant, that is as a hygroscopic substance which keeps the preparation moist. Glycerol helps to maintain texture and adds humectancy, controls water activity and prolongs shelf life in a host of applications.
10 Μαρ 2021 · Alcohols with two OH groups on adjacent carbon atoms are commonly known as glycols. The most important of these is 1,2-ethanediol (the common name is ethylene glycol), a sweet, colorless, somewhat viscous liquid. Another common glycol, 1,2-propanediol, is commonly called propylene glycol.
15 Σεπ 2022 · Commonly called glycerol or glycerin, 1,2,3-propanetriol is the most important trihydroxy alcohol. Like the two glycols, it is a sweet, syrupy liquid. Glycerol is a product of the hydrolysis of fats and oils. Ethylene glycol is the main ingredient in many antifreeze mixtures for automobile radiators.
Describe the structure and uses of some common polyhydric alcohols. Alcohols with two OH groups on adjacent carbon atoms are commonly known as glycols. The most important of these is 1,2-ethanediol (the common name is ethylene glycol), a sweet, colorless, somewhat viscous liquid.
