The answer is true.
<span>Antigens are molecules capable to induce an immune response, "targeted" by antibodies. Antigens are usually proteins, peptides, or polysaccharides but they can combine with lipids and nucleic acids and form more complex antigens (lipopolysaccharide). Usually, antigens are exogenous (foreign substances), but sometimes are part of the host itself (in an autoimmune disease). All of them contain an epitope which is a part of an antigen that can be recognized and bound by an antibody.</span>

Explanation:
Answer:
In the cholesterol biosynthetic pathway, the rate-limiting step is the reduction of HMG-CoA, which takes place in the existence of the HMG-CoA reductase enzyme. In case, when mutation takes place within the mentioned enzyme, it loses the tendency to combine with the substrate HMG-CoA, and as a consequence, the pathway fails to move forward and synthesis of cholesterol stops.
When the levels of cholesterol are high within the organism than the mutation of the enzyme HMG-CoA reductase results in less synthesis of cholesterol within the body of the organism and will eventually assist in balancing the level of cholesterol present within the body.
