Answer 5

high- density lipoprotein

Question 6

contains fewer proteins than lipids ( more lipids)

Answer 6

low- density lipoprotein

Question 7

why is cholesterol in low density lipoprotein is considered “bad”?

Answer 7

high blod levels of LDL associated with atherosclerosis

Question 8

life threatening blockage of arteries

atherosclerosis

Question 9

why is high- density lipo. is coonsidered good?

Answer 9

carries good cholestrol away from cells and towards the liver for elimination from the body

Answer 10

chemistry

Question 11

protein structure is a sequence of amino acids in a chain

Answer 11

primary

Question 12

protein structure is formed by folding and twisting of amino acid chain

Answer 12

secondary

Question 13

formed when the twists and folds of the secondary structure fold again to form a larger 3-dimensional structure

Answer 13

tertiary

protein structure is a protein consisting of more than one folded amino acid chain

Answer 14

quaternary

Question 15

types of lipids

Answer 15

triglyceride
phospholipids
cholesterol
