◉ Primary storage form of carbohydrate in animals (2000 kcals)
Answer: Glycogen
◉ Average person stores about ________ kcals as fat!
Answer: 100,000
◉ Properties of Lipids:
Answer: - Do not readily dissolve in water
- Fats are solid at room temperature
- Oils are liquid at room temperature
- Triglycerides are the main form of lipids in food and body (Storage)
- Energy dense (9 kcal/ gm)
◉ The Lipids:
Answer: - Triglycerides (95% of lipids in foods and bodies)
- Phospholipids (Lecithin)
,- Sterols (Cholesterol)
◉ Saturated Fat:
Answer: - No double bonds
- Solid at room temperature
- Animal fats (Lard)
- Some plant oils (Coconut, palm)
◉ Unsaturated Fatty Acids:
Answer: - One or more double bonds
- Most plant oils
- Liquid at room temperature
- Likely to spoil
◉ Monounsaturated Fat:
Answer: - One double bond
- Olive oil (77%)
- Canola Oil (62%)
◉ To prevent spoilage/ rancidity of unsaturated fatty acids:
Answer: 1.) Store tightly covered
2.) Refrigerate
,3.) Add antioxidants
4.) Hydrogenate: Make saturated
◉ Hydrogenated Oils:
Answer: - Margarine, shortening (Crisco)
- Use polyunsaturated oil
- Hydrogen forced into oil
- Hydrogenate ===> Makes it spreadable
- Oil gets harder
- More saturated than original oil
◉ Hydrogenated Oils ==> Properties:
Answer: - Easy to handle
- Stores well (Prevents rancidity)
- High smoking point (Good for frying)
- PRODUCES *TRANS* FATTY ACIDS!!!
◉ Health Dangers of Excessive Trans Fatty Acid:
Answer: - Increases risk for heart disease
-- Raises blood cholesterol
-- Current intake is ~3% of total kcals
- Now on food labels
, ◉ Minimize Intake of Trans Fat ==> Limit Use of:
Answer: - Hydrogenated fats
- Deep- fried foods
- High fat baked goods
- Non- dairy creamers
◉ Essential Fatty Acids
Answer: - Body can only make double bonds in certain locations of a
fatty acid
- Needed for immune function, vision, cell membrane, and
production of hormone- like compounds
◉ Essential Substance
Answer: - A substance that, when left out of a diet, leads to signs of
poor health
- Add back, reverses condition
- Specific biological function
◉ Omega - 3 Fatty Acid
Answer: - Primarily form fish oil
- Also found in canola or soybean oil
