Document Summary
Nusc 1165 lecture 14 chapter 5: lipids (part ii) Cis and trans fatty acids (types of unsaturated fat) Cis fats: h atoms are attached to the same side of c double bond creates a bend or kink in the structure. Cis fats are liquid at room temperature (e. g. olive oil), as the bend in their structure prevents tight packing. Trans fats: h atoms attached on opposite sides of c double bond straight, similar to saturated fat structure. Hydrogenation: adding h atoms to the c double bond, making the fat more saturated. Nyc was one of the first cities to ban the use of trans fat in restaurants. Phosphoglycerides: glycerol molecule, 2 fatty acids and phosphate group. Lecithin: choline molecule added to the phosphoglyceride. Emulsifier: allows water and fat to mix by breaking large fat globules into smaller ones. Found in both plant and animal sources. Cholesterol: a sterol found only in animal sources.
