Andrew Sherratt's model of a secondary products revolution involved a widespread and broadly contemporaneous set of innovations in Old World farming.The use of domestic animals for primary carcass products was broadened from the 4th–3rd millennia BCE (c. Middle Chalcolithic) to include exploitation for renewable 'secondary' products: milk, wool, traction (the use of animals to drag ploughs ...
Secondary metabolites, also called specialised metabolites, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, archaea, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism.
By-products are sometimes called co-products to indicate that although they are secondary, they are desired products. For example, hides and leather may be called co-products of beef production. For example, hides and leather may be called co-products of beef production.
All that was known was that secondary plant metabolites were "by-products" of the primary metabolism and were not crucial to the plant's survival. Early research only succeeded as far as categorizing the secondary plant metabolites but did not give real insight into the actual function of the secondary plant metabolites.
Secondary metabolism (also called specialized metabolism) is a term for pathways and small molecule products of metabolism that are involved in ecological interactions, but are not absolutely required for the survival of the organism. These molecules are sometimes produced by specialized cells, such as laticifers in plants. [1]
Baking bread, regardless of whether it is made at home, in a small bakery, or in a large factory, is an example of secondary food processing. [2] Fermenting fish and making wine, beer, and other alcoholic products are traditional forms of secondary food processing. [4]
