Sugar groups

I4, (o) 5FU. aDegree of substitution of carboxymethyl groups based on the number of sugar groups. 

Some proteases show an esterase activity, especially in their catalytic activity for regioselective acylation of sugars. By utilizing this property, enzymatic synthesis of polyester containing sugar group in the backbone was demonstrated... 

In each nucleotide monomer of DNA or RNA molecules, a phosphate group is attached to the C-5 hydroxyl of each sugar residue in an ester (anhydride) linkage. These phosphate groups in turn are linked in diester bonds to neighboring sugar groups of adjacent nucleotides... 

Figure 1.41 Polynucleotides are formed through phosphodiester bonds linking the associated sugar groups together. In DNA, the 3 -hydroxyl of one deoxyribose unit is bound to the 5 -hydroxyl of the next, creating direction in the polymer backbone.

Figure 1.42 The three pyrimidine bases common to nucleic acid construction. Cytosine and thymine are found in DNA, while in RNA, uracil residues replace thymine. The associated sugar groups are bound in N-glycosidic linkages to the N-l nitrogen.

Add to the washed cells 60 pi of a 5 mM concentration of the phosphine derivative to couple to the azido-sugar groups on the cell surface (e.g., biotin-PEG-phosphine). 

Figure 22.15 Glycolipid components included in liposome construction may be used to couple antibody molecules by using conjugates of lectins with the proper specificity for binding the sugar groups.

All previous observations in the sugar group are in such complete agreement with the van t... 

There are 10 base pairs in a complete turn of the helix, which spans a distance of 3.4 nm. The outside diameter of the helix is about 2nm. By convention, the double stranded DNA sequence is written from left to right the 5 end (position 5 of the sugar group) is assigned to the top left-hand strand. 

Incorrect Each compound composes an amino sugar group and a nitrogen-free sugar group bound directly to a 14-membered-ring aglycon moiety. 

D. The binding of polysaccharide substrates that have six or more sugar groups to lysozyme, the enzyme in tears and saliva that cleaves such molecules, induces strain in the sugar nearest the active site making the nearby bond more susceptible to hydrolysis.
