From Eric Kvaalen
In your article “11 steps to a better brain” (28 May, p 28) you say that triglyceride is a “cholesterol-like substance”. Triglyceride is a general term for a whole class of fat molecules. Chemically they are not at all similar to cholesterol, apart from consisting mostly of hydrogen and carbon, with a few oxygen atoms. The only real similarity is that high levels of both are associated with atherosclerosis.
