Study Notes
Fatty Acid Chains
- Long-chain fatty acids have 13 or more carbons.
Triglyceride Formation
- When an 'OH' from the glycerol molecule binds to an 'H' from the fatty acid, an ester bond is formed.
Characteristics of Triglycerides
- Triglycerides with saturated fatty acids are usually solid at room temperature because the straight-chain fatty acids can pack together tightly.
Digestion of Triglycerides
- Lipase is the enzyme that breaks down triglycerides into free fatty acids and monoglycerides in the saliva, stomach, and pancreas.
Function of Bile Salts
- Bile salts emulsify fats, breaking them down into smaller droplets, increasing the surface area for lipase to act on.
Reassembly of Triglycerides
- Fatty acids and monoglycerides reassemble into triglycerides in the small intestine.
Daily Fat Consumption
- The recommended range for daily fat consumption is 20-35% of total daily calories, according to the National Academies of Medicine.
Unsaturated Fatty Acids
- Polyunsaturated fatty acids are not saturated with hydrogen atoms.
Omega Fatty Acids
- A fatty acid with a double bond 6 carbons from the end has an omega-6 designation.
Monounsaturated Fatty Acids
- Oleic acid is a monounsaturated fatty acid that can be made by the human body.
Partial Hydrogenation
- The result of partial hydrogenation of liquid oils is the formation of trans fats.
