These stimulants tend to increase alertness without the peripheral (body) effects or addiction/tolerance/abuse potential of traditional stimulants (such as amphetamine), as they lack direct dopaminergic action. Their effect on sleep structure is not fully established and may reduce quality of sleep.
Trans fats, or trans-unsaturated fatty acids, trans fatty acids, are a type of unsaturated fats that are uncommon in nature but became commonly produced industrially from vegetable fats for use in margarine, snack food, packaged baked goods and frying fast food starting in the 1950s.nly unsaturated fats can be trans or cis fat, since only a double bond can be locked to these orientations. Saturated fatty acids are never called trans fats because they have no double bonds. Therefore, all their bonds are freely rotatable.
To understand the difference between unsaturated fats and trans fat, it is best to understand what creates a fat. Fats are a group of compounds known as glycerides. Fatty acids attach to glycerides. These fatty acids are molecules that are composed of hydrogen and carbon atoms. There are two types of fatty acids--saturated and unsaturated acids, which attach to create saturated and unsaturated fats. Fats are an essential part of the human diet and are one of the body's major sources of energy. The human body is only able to obtain energy by breaking down fats, carbohydrates and proteins.
