Okay, now you're probably thinking Hey Burn! LDL is cholesterol, it's the bad cholesterol! Ugh. Before I go any further, we need to go over some basics. Cholesterol is cholesterol. There is no "good" and "bad". Cholesterol is only one thing, and it's vitally important to every cell in your body. LDL and HDL are something different. They're not cholesterol at all, rather they are the molecules that carry cholesterol (and other fats) throughout the body to places where it is needed. Cholesterol can't just float around the blood by itself; it needs a carrier. Just imagine LDL as the "boat", and think of cholesterol as the "cargo". Here's a nice little diagram of an LDL particle. This little guy will be the subject of today's post.
The LDL particle, chock full of cholesterol. |
You can see here that the LDL particle is full of cholesterol. LDL particles can vary in how much cholesterol they hold, and their size is proportional in this way. Small ones hold smaller amounts of cholesterol, while larger ones hold more cholesterol.
