I went down to the Lincoln Diner Had my breakfast there. My bacon and eggs were so good. Fried potatoes, none can compare. Ate my food so quickly. You’d think I was in a race. Fats were mixed with saliva, Antibiotic, some water, and lipase. Fatty acids were formed in the process Not much I would say. But it served as a major trigger To release my CCK.

CCK does so many things, All are worthwhile. But what was important for my breakfast, My gall bladder dumped some bile. That bile bit off a little fat. Inside it, the fat would dwell. Held that fat for lipase And formed a new micelle. The lipase made fatty acids Then the micelle was quickly gone. The fat had been transported Into a chylomicron.

The fat oozed to my lymph. It’s enough to make you shiver, And it began its slow journey That ended in my liver. The fat was then repackaged And placed into a VLDL From there it went to my bloodstream Everything was going so well. Apo receptors on my fat cell Were begging it to come in But first it must be invited By big ol’ insulin.

Lipoprotein lipase was awaiting For a word from insulin. To allow the fatty acids To cross membrane and come in. The VLDL then shrunk To a smaller IDL. It could return to the liver Or go into another body cell. If it returned to the liver It may again be a VLDL. But if it went back to my body It could become a LDL.

It could change its apo profile And join the enemy.
