Animal resources proteins

Wool, as a keratin, is a highly cross-linked, insoluble proteinaceous fiber, and few animals have developed the specialized digestive systems that aUow them to derive nutrition from the potential protein resource. In nature, these few keratin-digesting animals, principally the larvae of clothes moths and carpet beetles, perform a useful function in scavenging the keratinous parts of dead animals and animal debris (fur, skin, beak, claw, feathers) that ate inaccessible to other animals. It is only when these keratin-digesting animals attack processed wool goods that they are classified as pests. Very often they enter domestic or industrial huildings from natural habitats such as birds nests. 

The isotopic composition of carbon in the proteins, which are one of the main components of animal tissues, reflects the nature of the food resources in the diet of the animals. Determining the relative abundance of the stable isotopes of carbon in the proteins of bones or hair, for example, can facilitate understanding of the effects that different types of plants or animal food resources had on ancient diets (Katzenberg 2000 Burton 1996). 

In the development of the protein-fatty acid condensates it was possible to combine the renewable resources fatty acids (from vegetable oil) and protein, which can be obtained from both animal waste (leather) as well as from many plants, to construct a surfactant structure with a hydrophobic (fatty acid) and a hydrophilic (protein) part (Fig. 4.12). This was carried out by reacting protein hydrolysate with fatty acid chloride under Schotten-Baumann conditions using water as solvent. Products are obtained that have an excellent skin compatibility and, additionally, a good cleaning effect (particularly on the skin) and, in combination with other surfactants, lead to an increase in performance. For instance, even small additions of the acylated protein hydrolysate improve the skin compatibility. An... 

Oceans are the Earth s most valuable natural resources, which provide majority of the food in the form of fish and shellfish (about 200billion pounds are caught each year). Oceans are the richest resource for numerous biomedically important chemical as well as the protein molecules, which are ranging from the general medication purposes to the specific therapeutic applications (Jimeno, 2002 Vo and Kim, 2010). While the use of floristic resources in traditional medicine has been widely explored, there is a paucity of information regarding the utilization of faunistic resources (Alves and Rosa, 2006), and as such, the medical value of animal species has not been included in the calculations of economic value of biodiversity by the World Conservation Union (IUCN) (Alves et al., 2009 Pearce and Moran, 1994). 

The rich proteins from shrimp and crab are a positive notion nowadays for the supplementing of high ranked nutrition for many of the patients of nutrition depletion. The collagen and other protein disorders can be overcome by the intake of these crustaceans regularly. However, the financial limitations and the inadequacy of fishing profound disturbances due to the human population and pollution many of the developing nations are underutilize these animals. In addition, chitin and its derivatives are vastly known for their biomedical importance however, the utilization of the crustacean foods is restricted mostly to Asian countries, and many of the developed, developing, and underdeveloped countries are henceforth advised well for the proper implementation of these medicinally valuable resources.
