Many species take up mono-, di- and trisaccharides into the cell through porins or transporters, while longer oligosaccharides require specialised systems, such as TonB-dependent transporters (TBDTs) or other outer membrane proteins. Usually these have a high specificity to discrete glycan structures...
Interestingly, a host of bacterial peptidoglycan fragments have been shown to be recognized by the human immune system as well and bind to nucleotide-binding oligomerization domain-like receptors, or NOD-like receptors. Structural similarities between Cyr1 protein and NOD proteins suggest that these ...
Describe the catabolism of fatty acids, proteins, and carbohydrates. (a) Describe the structure of carbohydrates, lipids, and proteins. (b) Give an example of each. What is the breakdown products for Carbohydrates, lipids, proteins and Nucleic acids?
There are some similarities and differences in the structure and function of starch and cellulose. Briefly compare these two substances and describe two major differences and two similarities of these substances. Identify three atoms that are common to carbohydrates, lipids, and proteins. Explain how...

In fact, pulses are currently regarded as functional foods mainly due to the presence of a number of bioactive compounds (fibre, some proteins, resistant starch, phenolic compounds) which, in adequate proportions, support important biological functions such as the stabilization of glycemic and ...
The family of glycan receptors such as c-type lectins, galectins, selectins, and siglecs could bind to milk oligosaccharides on intestinal epithelium and immune cells [33]. It has been known that lectin receptors are glycan-binding proteins related to immune response and cell recognition [120,12...
Monomeric character of the modified proteins was confirmed by sedimentation equilibrium ultracentrifugation and by their high resolution X-ray crystal structures, whereas their binding to carbohydrates was assessed by isothermal titration calorimetry. Cell-based antiviral activity assays utilizing different ...
For mammals and even more so for bacteria, the diversity of the monosaccharides used as the building blocks of carbohydrate sequences is significantly larger than that for the residues in proteins or nucleic acids. From the GLYCOSCIENCES.de database a total of 35 different monosaccharides were fou...
a protease and, significantly for HSV-1, HSV-2 and VZV, a thymidine kinase. Anti-herpes virus agents often show a broad spectrum of activity across the family, a consequence of structural similarities between the functional proteins, although the presence or absence of the thymidine kinase is ...
