Document Summary
: (most leftover): chylomicron, vldl, ldl, hdl, ffa-albumin (least leftover) : - starts in mouth as saliva is added, ~1l of saliva secreted per day. Due to polar vs. non-polar forces that"re at play. Are a combo of phospholipids, some mg, lots of fatty acids, cholesterol, fat soluble vitamins and bile acids. : - soluble fibre (whole grains, oats, beans) binds some cholesterol and leads to its excretion (therefore not absorbing it); fibre needs to be consumed with cholesterol for this to occur. Pufas reduce ldl levels directly, cis-mufas lower ldl and raise hdl (both found in plant-source fats. : - ldl is more likely to react with blood vessel walls. Chylomicrons and vldl stay in blood for <1 hour, but ldl particles remain for days (depends on the amount of fat consumed) : - the protein undwinds until its just a chain of exposed amino acids.
