Cholesterol? Cholestrole is a common misspelling of cholesterol.
Cholesterol is a waxy substance found in the body's cells. Your body uses this substance to hold cells together and to make hormones, vitamin D, and substances that help you digest foods. There are two main types of lipoproteins that help move cholesterol through the blood stream, one that is good (HDL) and one that can potentially be bad (LDL). Tests that can determine your cholesterol level generally detect "good cholesterol," "bad cholesterol," and total cholesterol.
