Glycerol and also Fatty Acids

A fat molecule consists of 2 major components: glycerol and fatty acids. Glycerol is an alcohol via three carbons, 5 hydrogens, and three hydroxyl (OH) teams. Fatty acids have a lengthy chain of hydrocarbons with a carboxyl group attached and may have 4-36 carbons; yet, most of them have 12-18. In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. Throughout the ester bond development, three molecules are released. Due to the fact that fats consist of 3 fatty acids and a glycerol, they are additionally called triacylglycerols or triglycerides.

Unsaturated fats or oils are normally of plant origin and contain cis unsaturated fatty acids. Cis and trans show the configuration of the molecule around the double bond. If hydrogens are current in the exact same airplane, it is described as a cis fat; if the hydrogen atoms are on 2 different planes, it is referred to as a trans fat. The cis double bond causes a bfinish or a “kink” that prevents the fatty acids from packing tightly, keeping them liquid at room temperature.
