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.
These names describe the structure of the fatty acid in terms of whether it is fully loaded with hydrogen. Fatty acids also differ in the length of the carbon chain. Short-chain fatty acids have less than eight carbons. Medium-chain fatty acids have 8 to 14 carbons and long-chain fatty acids have 16 or more carbons.nsaturated Fatty Acids: These are called unsaturated because they have lost one or more pairs of hydrogens from their carbon chain. Unsaturated fatty acids include mono-and polyunsaturated fatty acids (PUFAs). When hydrogen pairs are removed, the fatty acid molecule develops a kink or bend, known as a double bond.
