The difference between saturated and unsaturated fats lies in the bond, because the shapes determine how the various fats act in the body.
Fat provides fluidity.
The fats, or lipids, in milk act as the surfactants.
Neutral fats help in keeping the body warm by insulating. They also act as a padding for the body. An example of neutral fat is Monoglyceride.
Emulsification of fats is necessary because a fat globule has large surface area for enzymes to act upon it. Emulsification reduces the surface area and then more enzymes can act upon it and thus can produce more energy.
Bile contains bile slats that help in the process of emulsification of fats without which fats cannot be digested. emulsification of fats also increases the surface area of the fat malecules for lipase to act on.
Yes, fats act as a stored energy source in the body. Excess calories consumed are stored as fat in adipose tissue and can be used by the body for energy during times of low calorie intake or increased energy needs.
Lecithin prepares fats for hydrolysis by forming emulsions, which helps to disperse the fats into smaller droplets in water, increasing the surface area available for enzymes to act on. This process makes it easier for lipases to access and break down the fats into their component fatty acids and glycerol.
Bile salts do not digest fats. They cause the fats to become smaller and that increases the surface area so that enzymes in the digestive tract can act quickly.
The pancreas secretes enzymes that acts upon fats, carbohydrates, and protein. For example, the enzyme lipase helps to break down fats. Other enzymes are protease and carbohydrase.
Fats, waxes and oils are all also known as lipids.
Trans fats are unsaturated fats which have have same/simlar stucture to saturated fats therefore act as saturated fats. Trans fats are present in foods which contain vegetable fat which has been hydrograted partly to me soild. Pizzas can contain trans fats due to how the fat in the pizza base is made or trans fats naturally found in cheese. Trans fat levels should not go over 2g per person per day therefore having some trans fats is not too bad however you should limit the amount of trans fat you from.
