Glycerol and Fatty Acids
A fat molecule consists of two key components: glycerol and fatty acids. Glycerol is an alcohol with 3 carbons, 5 hydrogens, and three hydroxyl (OH) groups. Fatty acids have a lengthy chain that hydrocarbons v a carboxyl group attached and may have 4-36 carbons; however, many of them have 12-18. In a fat molecule, the fat acids are attached to every of the three carbons of the glycerol molecule through an ester bond with the oxygen atom. Throughout the ester shortcut formation, 3 molecules room released. Because fats consists of 3 fatty acids and a glycerol, castle are additionally called triacylglycerols or triglycerides.

Unsaturated fat or oils are usually of tree origin and also contain cis unsaturated fat acids. Cis and trans indicate the construction of the molecule around the dual bond. If hydrogens are current in the very same plane, it is referred to as a cis fat; if the hydrogen atoms room on two various planes, it is described as a infectious diseases worldwide fat. The cis twin bond causes a bend or a “kink” that avoids the fatty acids from pack tightly, maintaining them liquid at room temperature.
