Glossary

ENATIOMERS: are chiral molecules that are mirror images of one another. : An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed onto it. INVERTOMERS: Invertomer is a synonym of . Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more and are not mirror images of each other. E-The highest priority group are on opposite sides of the double bond. Z- The highest priority group are on the same sides .R- clockwise. S- Anticlockwise v Time-Lines

Description Image Why most of the food stuffs only contain trans fats? Figure-

Trans fats are unsaturated fats with a specific chemical structure,where the hydrogen atoms are on the opposite sides of the double bond. Trans fats are easily digested by the body because of the trans configuration enzymes can easily catalyse these fats.And also due to its non polar nature these are insoluble in water.Trans fats are also less expensive than the

alternatives and do not become

rancid. However,trans fats are harmful for our body.

Interesting facts

Essential fatty acids:

Linolenic acid is a type of fatty acid. It can refer to either of two octadecatrienoic acids that is with an 18-carbon chain and three double bonds, which are found in the cis configuration, or a mixture of the two. Linolenate in the form of esters of linolenic acid is often found in vegetable oils; traditionally, such fatty acylates are reported as the fatty acids: α-Linolenic acid and γ- Linolenic acid,

They are so necessary for health, and they cannot be produced within the human body. They must be acquired through diet.
