Hydrogenation is a chemical process in which hydrogen gas is bubbled through a liquid oil in the presence of a catalyst, often a reactive metal such as platinum or nickel. The resulting reaction forces unsaturated fatty acids to accept additional hydrogen atoms and become at least partially saturated.
From Wikipedia, the free encyclopedia. For other uses, see Fixation. In population genetics, fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) to a situation where only one of the alleles remains.ixation can refer to a gene in general or particular nucleotide position in the DNA chain (locus). In the process of substitution, a previously non-existent allele arises by mutation and undergoes fixation by spreading through the population by random genetic drift and/or positive selection.
