Lipids Nutrition

Lipids

• contain high carbon and nitrogen molecules

• can easily be dissolved in water

• can only be found in plant

• are non-polar organic molecules

What is a monomer of a lipid?

• A glycerol head with fatty acid tails.

• Three fatty acids.

• A five-sided carbon ring.

• A saturated or unsaturated tail.

The different type of lipids may depend on the

• location of carboxylic group

• degree of unsaturation

• location of double bond

• length of hydrogen bond

An unsaturated lipid contains

• more oxygen than hydrogen

• double bonds

• ionic bonds

• only one fatty acid

Saturated fatty acids

• had a low melting point

• exist in liquid form at room temperature

• had a high boiling point

• contain one double bond

___________ are some functions of lipids.

• storing energy and  cell membrane structure
• providing actin & providing myosin
• cellulose structure and digestive assistance
• storing & transferring genetic info

Omega 3 fatty acids

• can be found in oily fish

• act as pro inflammatory

• act as anti inflamatory

• can be found in chicken and eggs fed with omega 3 fatty acids

These cells uptake fatty acids directly from the blood stream

• hepatocytes

• brown adipocytes

• white adipocyte

• muscle

Carnitine palmitoyltransferase I (CPT1) is needed to transport fatty acids through mitochondria membrane for beta oxidation process

• True

• False

Excess Omega 3 is more important than a balance between omega 3 and omega 6 fatty acids for healthy wellbeing

• True

• False
