Study Notes

Phospholipids

Unique chemical structure enables solubility in both water and fat.
Commonly used as emulsifiers in the food industry.
Essential components of cell membranes in the human body.
Lecithin is a notable type of phospholipid.

Sterols

Characterized by a multiple-ring structure, distinguishing them from other lipids.
Include important compounds like cholesterol, bile, vitamin D, and certain hormones.
Cholesterol is primarily sourced from animal-derived foods, highlighting the dietary origins of sterols.
