Lipoprotiens

Time to switch to biochemistry. A lipoprotein is a molecule that contains both proteins and lipids. This combination allows fats to move through water. Originally fats cannot move though water because they are hydrophobic (afraid of water). Why do we need movement of lipids throughout our body? So they can be metabolized, of course! Dietary fats are emulsified in the gut by bile salts secreted from the pancreas, and whatever else is not needed diffuses through to the epithelial cells, re-esterified, and packaged into chylomicrons. These chylomicrons are then used to deliver the lipids, these specific type known as triglycerides, into skeletal muscle and adipose cells.

Answers to yesterdays question: The extra chromosome ends up in the cell of a Klinefelter's Syndrome individual due to a mix up during meiosis. During either Stage I or Stage II the sister chromatids don't separate from each other correctly, ending up with an extra chromosome in one gamete! Another disorder with an extra chromosome is Down Syndrome, which is an extra of chromosome 21 (often called Trisomy 21).
