BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cholesterol is a lipid in your blood. Your body needs it to help you take in fats and vitamins and make hormones. Cholesterol and triglycerides avoid water, so they can’t travel through blood themselves. This is why they combine with proteins to make lipoproteins that can move throughout your body.

Detailed explanation-2: -For the fat-like cholesterol to travel in the bloodstream, the cholesterol is packaged in molecules called lipoproteins. These small packages are made of fat (lipid) on the inside and proteins on the outside. Two of the lipoproteins that carry cholesterol throughout the body are LDL and HDL.

Detailed explanation-3: -Lipids are fat-like molecules that circulate in your bloodstream. They can also be found in cells and tissue throughout your body. There are several types of lipids, of which cholesterol is the best-known. Cholesterol is actually part lipid, part protein.

Detailed explanation-4: -Lipids are compounds that are insoluble in water but are soluble in organic solvents such as ether and chloroform. Lipids that are important to our discussion include fats and oils (triglycerides or triacyglycerols), fatty acids, phospholipids, and cholesterol.

Detailed explanation-5: -Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.
