Document Summary
Omega-3 fatty acid and exercise performance: increased insulin sensitivity with increased ability to burn fat results in increased ability to store glycogen, stress hormones inactivate acetyl coa carboxylase. Digestion of fats: 95% of dietary lipids are triacylglycerol, 5% phospholipids or sterols, most dietary lipids are made up of long chain ffa (>14 c, due to insolubility in water digestion requires. Lipases and cholesterases from pancreas to hydrolyze into ffa, glycerol, cholesterol, and phospholipid. Digestion of fats diagram: digestion begins with dietary fats that are broken down into component parts by lipase and bile. Chylomicrons are composed of lipid and protein, that package dietary fats and enter blood so it can be soluble in water: repacked chylomicrons enter the blood, break apart into components again to go to various tissues. Ffa, g, c, ph and pr are repacked by liver. Can be repacked into other lipoproteins such as vldl, ldl and hdl that can be released into the blood.
