Lipids and Biomolecules Flashcards

Flashcards about Triglycerides, Saponification, and Biomolecules Bonds

Explain how the structure of triglycerides relates to whether they are oils or fats, incorporating intermolecular forces (IMFs).

Triglycerides with more alkenes have kinks that reduce London forces and stacking, resulting in a lower melting point and liquid state at room temperature (oil). Triglycerides with fewer kinks have increased London forces and greater stacking, resulting in a higher melting point and solid state (fat).

What products are formed when a triglyceride is saponified and what reagent is used?

Saponification of a triglyceride with NaOH produces glycerol and soap (fatty acid salts).

Peptide bond

A bond that holds each unit to the next unit in proteins.

Glycosidic bond

A bond that holds each unit to the next unit in Polysaccharides.

3,5-phosphodiester bond

A bond that holds each unit to the next unit in Nucleic acids.

Esters bond

A bond that holds each unit to the next unit in Triglycerides (glycerol to fatty acids).

Phosphoester bonds

A bond that holds each unit to the next unit in Phospholipids (glycerol to phosphate).

Phosphaester bund

A bond that holds each unit to the next unit in Sphingolipids (sphingosine to phosphate).
