Triglycerides and Fatty Acids Katie and Taz

Structure of Fatty Acids Fatty acids can be either saturated or unsaturated Saturated being without multiple bonds Unsaturated being with multiple bonds They are the products of broken down fats Stearic acid Linoleic acid

Fatty acids can be either saturated or unsaturated

Saturated being without multiple bonds

Unsaturated being with multiple bonds

They are the products of broken down fats

Triglycerides Are triesters where the alcohol glycerol is esterified with 3 fatty acids left part : glycerol right part from top to bottom : palmitic acid oleic acid, alpha-linolenic acid

Are triesters where the alcohol glycerol is esterified with 3 fatty acids

Saponification The hydrolysis of triglyceride esters, which produces soaps (the salt of the fatty acid) A metallic base reacts with a fat or oil If NaOH is used a hard soap is formed If KOH is used a soft soap is formed Soaps are usually a mixture of triglycerides and their quality depends on the oil or fat used to make it
