Stage 2 Chemistry 3.9 Triglycerides (Part 1 of 2)

Описание: This video series covers Subtopic 3.9 Triglycerides

This addresses the Science Understandings:
"Edible oils and fats are esters of propane- 1,2,3-triol (glycerol) and various carboxylic acids.
• Draw the structural formula of an edible oil or fat, given the structural formula(e) of the carboxylic acid(s) from which it is derived.

Triglycerides can be hydrolysed to produce propane-1,2,3-triol and various carboxylic acids.
• Identify and draw the structural formulae of the alcohol and acid(s) from which a triglyceride is derived, given its structural formula.

Triglycerides may be saturated or unsaturated.
• Describe and explain the use of a solution of bromine or iodine to determine the degree of unsaturation of a compound. Draw the structural formula of the reaction product.
• Explain how the degree of unsaturation causes differences in the melting points of edible oils and fats."

This relates to the SACE Stage 2 Chemistry Subject Outline.
