Question

3. Cholesterol is pictured below. Label the areas of the molecule as being 'hydrophilic' or 'hydrophobic.' A. What do 'HDL' and 'LDL' stand for? Which one is "good" cholesterol, and which one is "bad" cholesterol? B. How does cholesterol circulate in the bloodstream? c. What action triggers cholesterol synthesis? What would cause a decrease in LDL? What would cause more HDL to be produced?

Answer 1

C4 но Hydrophobic Hydrophilic part > Only the oH group is the part of chloresterol which is Hydrophilic jie water loving group - And other part except -OH group, is Hydrophobic part of the chloresterol i-e water hating group HDL stands for High-density lipoprotein and LDL stands for low-density lipoprotein. The High-density lipoprotein is the good cholesterol. Good chloresterol that helps protect against heart disease. > low density lipoprotein is the bad. cholesterol, and which is a major contributor to clogged as tenies How The chal cholesterol in our blood comes. from two sources. the foods you eat. and our liver. Cholesterol and other tats are carried in our bloodstream as Spherical particles called lipoproteins. The two most commonly known lipoproteins are low-density lipoproteins and high- olensity lipoproteins.

cholesterol is minimally soluble in water, t. cannot dissolved and travel in the water- based bloodstream. Instead, it transported in the bloodstream by lipoprotein that are water-soluble and carry Chlolesterol C cholesterol serves as a precursor for the biosynthesis of steroid hormones bile acid and vitamin D. chlo cholesterol is the principal sterol synthesized by all animals. Abetalipoproteinemia CABL and familial hypo betalipoproteininemia are relatively uncommon inherited disorders of lipoprotein metabolism that cause low cholesterol level. HDL having high triglyceride level can also increase a risk of heart disease Still, there is some evidence that high triglycerides, on their own increas the risk of clise ase.
