The most important part of photosynthesis occurs in the chloroplasts. These small photosynthesis factories buried within the leaves house chlorophyll, a green pigment secreted in the chloroplast membranes. Chlorophyll absorbs a wide range of the spectrum of sunlight, giving the plant as much energy as it can for its reactions.
The liver makes cholesterol to use in production of bile. Bile-acid-binding resins attach to the bile acids, causing the liver to use more cholesterol than it normally does. When effective, this type of medication lowers the overall cholesterol levels in the body. Resins available for prescription are L-Cholest, Prevalite and Questran (cholestyramine), Welchol (colesevelam) and Colestid (colestipol).
For many people, abnormal cholesterol levels are partly due to an unhealthy lifestyle. This often includes eating a diet that is high in fat. Medicines such as certain birth control pills, diuretics (water pills), beta-blockers, and some medicines used to treat depression may also raise cholesterol levels.
