Ruminant TFA which are produced by biohydrogenation in stomach of ruminant animals include vaccenic acid and rumenic acid which is a conjugated linoleic acid isomer. However, partial hydrogenation reconfigures most of the double bonds that do not become chemically saturated, so that the hydrogen atoms end up on different sides of the chain.

Usually the hydrogen atoms at a double bond in a natural fatty acid are positioned on the same side of the carbon chain. Many baked foods require semi-solid fats to suspend solids at room temperature; partially hydrogenated oils have the right consistency to replace animal fats such as butter and lard at lower cost.
