A carefully constructed regression model can be used to search for functional products effectively.
The global and strong demand of consumers for naturals, namely for functional products which are beneficial, and not harmful, both to health and to the environment, will continue to drive the demand of citric acid as ingredient in beverage, food, pharmaceutical and cosmetic products.
More precisely, the author suggests that the most appropriate supply chain strategy for functional products (with predictable demand) would be the pursue of physically efficient processes, whereas in case of innovative products (with unpredictable demand), supply chain should pursue market-responsiveness.
Pseudogenes are "fossil" copies of functional genes that have lost their potential as DNA templates for functional products [ 1- 6].
To obtain a broad overview of their potential for functional products, several metabolites were analysed in mature plants (total phenolics, ascorbic acid (AA), total flavonoids and total antioxidant capacity), all attributed as antioxidants with use in fields such as pharmacognosy, functional foods and nutraceuticals (Arts and Hollman 2005; Scalbert et al. 2005; Gallie 2013).
In other words, evolution is selecting for the (functional) product and not for an intermediate step, so an initial RNA-based network could not have come into place one reaction at a time, but only as an already operational entity.
2. Degree of specialization:Organizations that prefer high degrees of specialization may opt for a functional, product or market structure to support their strategy.
For example, a particular segment of DNA is a gene as a consequence of its ability to code for a functional product, which depends on both DNA elements external to this gene and non-genetic factors.
The historical definition of a pseudogene is a DNA sequence that looks like an active gene but has lost its ability to code for a functional product, due to more or less extensive mutational disablements.
With regard to the tissue-specific transcription and reproducible RNA primary structure the human transcribed locus Hs.633957 may be considered "a complete chromosomal segment responsible for making a functional product," which is a definition of a gene according to Snyder and Gerstein [ 28].
