Concept explainers
Interpretation:
The name of lipoproteins that transport triacylglycerols from intestinal cells to the bloodstream has to be identified.
Concept introduction:
Triacylglycerols are lipid molecules that are formed by fatty acids. They constitute around 98% of the total dietary lipids. These lipid molecules undergo digestion/breakdown into simpler forms in the
In a lipoprotein, lipids and amino acids are present. Therefore, lipoproteins are conjugated proteins that help in the suspension of lipids and their transportation through the bloodstream.
