How are lipids metabolized in the body?
Lipids are fats, that together with carbohydrates and proteins make up the main parts of cells in organic life. They are a fuel source. Cholesterol is a lipid.
Fat takes longer to break down in the intestinal tract because it does not break down in water. The pancreas secretes an enzyme called lipase that helps to break the fat molecules down into smaller molecules to ease digestion and absorption by the body.
Lipids are concentrated sources of energy and provide fuel for aerobic respiration. Lipids are a source of metabolic water. during respiration stored lipids are metabolized for energy, producing water and carbon dioxide. Stored lipids provide insulation. increased body fat levels in winter reduce heat losses to the environment.
Sugars and starches are, in fact, not lipids, but rather carbohydrates. Of the four biological macro molecules (carbohydrates/polysaccharides, proteins, nucleic acids, and lipids), lipids are hydrophobic (not water soluble), less easily metabolized, and waxy or slippery to the touch. In contrast, sugars and starches are energy storying molecules and are soluble in water, which is consistent with the definition of a carbohydrate.
Lipids are not water soluble, they are fat soluble (and are considered a kind of fat or oil). They have a high energy content and can be metabolized to release calories, but they have many other uses as well. Lipids help to create lasting structures within the body, since water soluble substances would not last in an aqueous environment. Lipids are also electrical insulators and are needed to insulate nerve axons so that they can…
Lipids are molecules provide by the diet and elaborate(metabolized) for the cell structures to be interspersed through the plasma membrane and part of the metabolic process of the cell, they are important molecules as other molecules are important for the metabolic process but they are not essential structures of the cell.
We know that through metabolism the body rids itself of alcohol. Alcohol must be metabolized to get it out of the body. To remove most substances from the body they are chemically reacted (metabolized) to make them more water soluble so they pass into the urine. Ethanol is oxidized by alcohol dehydrogenase (a group of enzymes) in the liver.
cornstarch is metabolized by the body into glucose. therefore, since diabetics are glucose intolerant, cornstarch would be contraindicated in their diet. cornstarch is metabolized by the body into glucose. therefore, since diabetics are glucose intolerant, cornstarch would be contraindicated in their diet.
