Unformatted text preview: dvantages of TAGs as stored fuels:
1. Carbon atoms of fat are highly reduced energy store – Oxidation TAGs ~ 9.5 cal/gm CHOs ~ 4.0 cal/gm
2. TAGs are hydrophobic
∴ lighter as no H2O TAGs insulate against the cold
Where are TAGs found?
In adipocytes as droplets of fat (under skin, abdominal cavity, and in mammary glands) Fat transportation in the Fat transportation in the body 1) Fatty acids
transported in the blood attached to the serum protein albumin
transported in the blood in lipoproteins (VLDL, LDL, HDL, chylomicrons) Lipids The Least You Lipids The Least You Need to Know! to recognise fatty acids
