Fats are also called triacylglycerols or lipids;\n\nthe structure is the result of an esterification reaction between one molecule of glycerol ( a tri-hydroxy alcohol ) and three molecules of fatty acid ( long-chain carboxylic acids ):\n\n R-OH + R-COOH --->  R-C(=O)OR + H20\n\nglycerol is H2C(OH)CH(OH)CH2OH;  the fatty acids are typically stearic ( C18H36O2 ) or oleic ( C18H34O2 ) acids.\n\nThe bonds holding the fatty acids to the glycerol part are called ester bonds (-C(=O)-O-C-)

Fatty acids are synthesized from acetyl CoA molecules in the body when there is an excess of energy.  Acetyl CoA  has two carbons in it, so when only acetyl CoA is used, you'll get an even number.  The body *can* synthesize odd numbered fatty acid chains, but it's complicated.\n\nHere's a link that explains fully the process:\n\nhttp://www.rpi.edu/dept/bcbp/molbiochem/MBWeb/mb2/part1/fasynthesis.htm\n\nHope it's not confusing.

apolipoproteins\n\nLipids (triglyceride (TG), cholesterol (Chol), phospholipids (PL), cholesteryl esters (CE)) are insoluble in plasma. These lipids combine with special proteins called apoproteins - apolipoproteins - to form lipoproteins and this process solubilises lipids in plasma. Therefore, the lipoproteins provide a transport system for lipids. Apoproteins are important not only in maintaining the structural integrity of lipoproteins and thereby facilitating the solubilisation of lipids, but they also play an important role in lipoprotein receptor recognition and regulation of certain enzymes in lipoprotein metabolism.

A. Important Classes of Lipids \n1. Fatty Acids - Long Chain Aliphatic Carboxylic Acids. \n2. Triacylglycerols - Esters of Fatty Acids with glycerol. \n3. Glycerolphospholipids - Esters of glycerol with fatty acids and phosphate derivatives. \n4. Waxes - Esters of a fatty acid with a long chain alcohol. \n5. Sphingolipids - Esters of Fatty Acids with Sphingosine \n6. Steroids - Polycyclic aliphatics. \n7. Prostaglandins and Leukotrienes - oxidized derivatives of C-20 fatty acids

That is fat in the blood.  It is best to eat a low fat diet, try to cut down on red meat.  Exercise will also help lower triglycerides.

1.  removal of dead blood cells\n2. stores platelets\n3. produces blood cells during fetal life.\n \n(p.s.  the "liver" metabolizes carbs, lipids, protein, processes drugs and hormones, excretes bilirubin, synthesizes bile salt, stores glycogen, phagocytize red blood cells, and activates vitamin D, Rodney)

HELLO Amina,\nGlycerols are actually a sort of derived lipids obtained by hydrolysis of fats with water at high temperatures and pressures. it is in fact a trihydroxy alcohol, which is sweet and viscous. It forms esters like Triacyl glycerols(TGs) or Diacyl Glucerols or Monoacyl Glycerols  (or otherwise called Tri Glycerides) with fatty acids and phosphates. TGs are neutral fats, which, like cholesterol form the fat content of the body. These TGs get oxidized inside the mitochondria of cells  in the absence  (or scarcity) of glucose and act as a source of energy during starvation or dieting. Glycerol esters of higher fatty acids remain solid in room temperature and examples of such TGs include various vegetable oils. \nFatty acid esters with phosphate groups(PO4=) can form phosphoglycerides when they contain glycerol as the alcohol. Such compounds are important as protectors of the nervous tissue. Egs include phosphatidyl choline, and Lecithin. The last one is also present in Heart and liver..\nOoohhh that was a pretty long answer. \nHope I didn't get too technical and i suppose iwas clear on the topic,\nSo long then..

Omega-3 fatty acids are important building blocks of our cell membranes, signaling pathways and neurological systems. They play a critical role in many functions in the body and are essential for good health. The benefits of omega-3 fatty acids in cardiovascular disease are so well demonstrated that the American Heart Association recommends increased fish intake and/or omega-3 supplements. Scientists and physicians have also discovered many other benefits of omega-3 fatty acids.

There are four that I am aware of. The bad fats are trans fats and saturated fats. The good fats are polyunsaturated and monounsaturated.

Blood is composed of several kinds of corpuscles; these formed elements of the blood constitute about 40% of whole blood. The other 60% is blood plasma, a fluid that is the blood's liquid medium, appearing yellow in color. The normal pH of human arterial blood is approximately 7.40 (normal range is 7.35-7.45). Blood that has a pH below 7.35 is acidic, while blood pH above 7.45 is alkaline. Blood pH along with arterial carbon dioxide tension (PaCO2) and HCO3 readings are helpful in determining the acid-base balance of the body. Blood is about 7% of the human body weight [1], so the average adult has a blood volume of about 5 liters, of which 2.7-3 liters is plasma. The combined surface area of all the erythrocytes in the human anatomy would be roughly 2,000 times as great as the body's exterior surface.\n\nThe corpuscles are:\n\n    * Red blood cells or erythrocytes (96%). In mammals, mature red blood cells lack a nucleus and organelles. They contain the blood's hemoglobin and distribute oxygen. The red blood cells (together with endothelial vessel cells and some other cells) are also marked by proteins that define different blood types.\n    * White blood cells or leukocytes (3.0%), are part of the immune system; they destroy infectious agents.\n    * Platelets or thrombocytes (1.0%) are responsible for blood clotting (coagulation)\n\nBlood plasma is essentially an aqueous solution containing 96% water, 4% blood plasma proteins, and trace amounts of other materials. Some components are:\n\n    * albumin\n    * blood clotting factors\n    * immunoglobulins (antibodies)\n    * hormones\n    * various other proteins\n    * various electrolytes (mainly sodium and chlorine)\n\nTogether, plasma and corpuscles form a non-Newtonian fluid whose flow properties are uniquely adapted to the architecture of the blood vessels.
