Q

explain how long chain FA are absorbed and transporte din blood?

A

packaaged into lipopritein (chylomciron) in GI epithelium, absordped intro lymph through alcreal, travels to left subclavian cein and into regular blood circualtion - chylomicron to fat cell where its too bigh to be absorbed so breaks down by enxyems into glycerol and FA which can be abrobed into cell by becoming triglcyerides and store in adipose

reminants liek cholesterol go back to liver and are recylceld into other lipproteins like VLDL which are released in blood

some more triglyc is dropped at fat cells and VLDL becomes LDL (low density - BAD chole)

Some LDL are taken up by apolipoprotein B on cells and metbaoized but there are limited receptors
soem also metabolized by HDL (agin limited)
Leftover LDL in blood oxidize on artery walls - CVD, hight BP, atherosclerosis

Bioavailability refers to how much of a mineral the body can absorb and use from the food we eat. Even if a mineral is present in a food, the body might not absorb all of it.
173
what are some examples of inhbitors iof mineral absorption
hytates (found in grains, beans, and seeds): They can bind to minerals like iron, zinc, and calcium, making them less available for absorption. Oxalates (found in foods like spinach, rhubarb, and tea): These can bind to calcium and reduce its absorption. Tannins (in tea and coffee): They can reduce the absorption of iron from plant-based foods. Calcium: Excessive calcium intake can inhibit the absorption of iron and magnesium
