¿qué relacion tienen los ácidos grasos con los triglicéridos? Respecto a sus estructuras químicas

Triglycerides are esters of fatty acids and  glycerol  

Explanation:

The fatty acid chains are usually 12 to 24 carbon atoms long. They can all be different, and they can have one or more C=C double bonds.

The image below shows a molecule of tristearin — a triglyceride ester of stearic acid (C₁₈) and glycerol.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
