HUMAN NUTRITION

Detailed explanation-1: -Unsaturated fats have one or more double bonds between the carbon atoms. These pairs of carbon atoms connected by the double bonds can be saturated by the addition of hydrogen atoms to them, thereby converting the double bonds to the single bonds and hence, the double bonds are called unsaturated.

Detailed explanation-2: -In unsaturated fatty acids, some carbon atoms are not bonded to as many hydrogen atoms as possible. Instead, they form double or even triple bonds with other carbon atoms. This causes the chains to bend (see Figure 2.6. 2).

Detailed explanation-3: -Unsaturated fats can undergo a hydrogenation reaction, a chemical reaction that changes their double bonds to single bonds. The unsaturated fat reacts with hydrogen gas in the presence of a metal catalyst (normally palladium, platinum, or nickel). This reaction reduces the number of double bonds in original fat.
