What are tristearin chemical properties?

What are tristearin chemical properties?

TRISTEARIN Chemical Properties,Uses,Production Colorless crystals or powder; odorless; tasteless. Insoluble in water; soluble in alcohol, chloroform, carbon disulfide. Combustible.

What is tristearin made of?

The structure of tristearin, a triglyceride with three molecules of stearic acid connected to a glycerol molecule by means of ester linkages, is shown in Figure 37-1B. Other triglycerides have a similar structure with alternative fatty acids esterified to the glycerol backbone.

Is tristearin a lipid?

The lipid core typically consists of triglycerides (e.g., tristearin), diglycerides (e.g., glyceryl behenate), monoglycerides (e.g., glycerol monostearate), fatty acids (e.g., stearic acid), steroids (e.g., cholesterol), or waxes (e.g., cetyl palmitate) (Fonseca-Santos et al., 2015).

What is tristearin used for?

Tristearin is a triglyceride, a glyceryl ester of stearic acid, derived from animal fats created as a byproduct of processing beef. It can also be found in tropical plants such as palm. It is used as tallow in the manufacture of candles and soap.

Is Tristearin a fat or oil?

Stearin /ˈstɪərɪn/, or tristearin, or glyceryl tristearate is an odourless, white powder. It is a triglyceride derived from three units of stearic acid. Most triglycerides are derived from at least two and more commonly three different fatty acids….Stearin.

Crystal structure Triclinic (β-form)
Space group P1 (β-form)

What is the chemical structure of glycerol?

Glycerol is a triol with a structure of propane substituted at positions 1, 2 and 3 by hydroxy groups. It has a role as an osmolyte, a solvent, a detergent, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite.

What is the chemical formula for triglyceride?

composition of fats Simple triglycerides are those in which each molecule of glycerol is combined with three molecules of one acid—e.g., tripalmitin, C3H5(OCOC15H31)3, the glyceryl ester of palmitic acid, C15H31COOH.

What is the formula for Tripalmitin?

Why glycerol is soluble in water?

Glycerol which is also known as glycyl alcohol, glycerin or glycerine is soluble in water. It has this property mainly because of its polyol (three -OH) groups ability to form hydrogen bonds with water molecules. The three -OH groups in glycerol are polarised and this helps them to easily dissolve in water.

When does tristearin solidify at 72 °C?

The Merck Index – An Encyclopedia of Chemicals, Drugs, and Biologicals. 13th Edition, Whitehouse Station, NJ: Merck and Co., Inc., 2001., p. 891 On heating above 55 °C it solidifies and melts again at 72 °C.

What makes up the inner core of tristearin?

The inner cores maybe consisted of both solid and liquid lipids. As solid lipid at room temperature, Glyceryl behenate, glyceryl palmitostearate, fatty acids (mainly stearic acid), triglycerides, tristearin, steroids, cetyl palmitate]

Which is the correct formula for tristearic acid ( TG )?

TG(18:0/18:0/18:0) is a tristearic acid triglyceride. Triglycerides (TGs) are also known as triacylglycerols or triacylglycerides, meaning that they are glycerides in which the glycerol is esterified with three fatty acid groups (i. e. fatty acid tri-esters of glycerol).

What’s the melting point of tristearin Alpha and beta?

3.2.5 Melting Point MP: 55 °C (ALPHA), 64.5 °C (BETA’), 73 °C (BETA)
