Triglycerides
- Not all made up of all the same FAs
Phospholipids
Sterols
- Cholesterol
- Important because it is precorser
- Makes testosteron, estrogen, tec
Transport
- Needs to bind to a blood protein
- Not all FA are teh same
Commonly consumed foods in terms of macronutrient content
- Almonds, avocados, steak
- High quality protein
- Has to be digestible
- Contains all essential AA
FA
- Hydrocarbon chain (organic molecule, 4 - 24 carbons)
- Short chain < 6
- Medium chain 6-12
- Long chain >12
- FA notation
- 18:0

Only page 1 are available for preview. Some parts have been intentionally blurred.

- 18 is number of carbons
- 0 is unsaturated bonds
- Example
- Butyric acid (4:0)
- This is saturated
- Stearic acid 18:0
- Saturated
- Effects of chain length
- Long - solid @ room temperature
- Short = liquid @ room temperature
- Triglyceride functions
- Energy source
- Beta oxidation of FA → lots of ATP
- Insulation/protection
- Lots of fat storage = subcutaneous and visceral fat (enters the portal, fatty
liver)
- Fatty liver
- High fat deposits
- Impaired depatocyte
- Improves bioavailability and transport of other fat soluble nutrients
- Fat soluble nutrients
- Vitamin A, D, E, K (need FA to absorb)
- Flavour, texture, odour of foods
- Fat that reaches temperature (this is what we smell
- Types of FA
- Saturated
- Monounsaturated
- Polyunsaturated
- Oleic acid
- Linoleic acid
- Linolenic acid (18:3)
- 3 unsaturated bonds
- Omega 3
- Drawing them (polyunsaturated FA)
- 1st is methyl end (CH3)
