Unsaturated Saturated Triglycerides Tend Acids Kink Structure Straight

Unsaturated triglycerides have kinks in their chains due to double bonds, which prevents tight packing and results in lower melting points (liquid at RTP). Saturated triglycerides, with straight chains, pack more densely and are solid at RTP.

Los triglicéridos insaturados tienen 'kinks' en sus cadenas debido a los dobles enlaces, lo que les impide empaquetarse estrechamente y resulta en un punto de fusión más bajo (líquidos a T.A.). Los triglicéridos saturados, con cadenas rectas, se empaquetan más densamente y son sólidos a T.A.

Front

Explain why saturated triglycerides tend to be solid at RTP whereas unsaturated triglycerides tend to be liquid.

Back

Melting point of saturated/unsaturated triglycerides

Unsaturated acids have one or more double/triple bond which cause a kink in the chain structure - it is not a straight line

Saturated acids have single bonds only so their structure is a straight line

In packing of fatty acids, saturated can sit much closer together than unsaturated due to unsaturated bonds having a kink

Therefore saturated - solids, unsaturated - liquid
