Using cellulose and chitin as examples, describe the features of the polymeric "structural" carbohydrates. Discuss where they occur in nature, and what gives these molecules the required rigidity to serve as structural materials.What are the chemical elements that form carbohydrates?The...
Chemical elementsthat are either present naturally in the soil or introduced by pollution are more usefully estimated in terms of ‘availability’ of the element, because this property can be related to mobility and uptake by plants. A good estimation of ‘availability’ can be achieved by measuri...

Chemically depolymerizing biomass polysaccharides to simple sugars is often controlled by the balance between depolymerization and degradation kinetics, which has limited the concentration of solutions that can be obtained and overall yields. The reversible stabilization of carbohydrates by acetal formation push...
The results confirm the general structure of macroaggregates, including four major classes of structural elements: carbohydrates, ester and amide functional groups, aliphatic, and organosilicon components. The water-soluble fraction of macroaggregates is mostly composed of carbohydrates with a minor ...
What chemical elements are found in milk?Chemical Elements:Chemical elements can be distinguished from each other based on the number of protons that their atoms have in the nucleus. For example, all atoms of the element fluorine have 9 protons in their nucleus....

The colonies are made up of two main elements: the food pots (honey and pollen), the nest (brood discs), in addition to auxiliary structures, such as the casing, batume, entrance tunnel (Camargo & Pedro,2003). To withstand long periods of adversity and protect their offspring, SLBs stor...
The contents of gossypol, total protein and amino acids, fiber and carbohydrates, and selected macro and trace elements in these products were determined and compared with each other and with those of soy meal products. Data reported in this work improved our understanding on the chemical ...
