Concept explainers
Interpretation:
The transportation of cholesterol around the body has to be given and if it leaves the liver then what will be its destination and use has to be given.
Concept introduction:
Cholesterol: it is a soft, fat-like, waxy substance found in the blood stream and all our body’s cells. It is an essential component of mammalian cell membranes where it is required to establish proper membrane permeability and fluidity. It is the principal sterol synthesized by animals.
LDLs- This is a lipoprotein which transport cholesterol and it is considered as the bad cholesterol.
Sterols are steroid alcohol which is occur naturally in plants, animals and in

- Which of the following describes how soluble fiber in the diet may lower blood cholesterol levels? Soluble fiber binds cholesterol in the colon and carries it out of the 1) body with feces. Soluble fiber binds cholesterol in the small intestine and carries it out 2) of the body in urine. 3) Soluble fiber digests cholesterol in the colon. 4) Soluble fiber sends a signal to the liver to produce less cholesterol.arrow_forwardWhat is High-density lipoprotein Cholesterolarrow_forwardWhy must cholesterol be transported through the bloodstream in lipoprotein particles?arrow_forward
