a and b ) Please name the following disaccharide. They are all are D forms. For example, ?−??????????????????−?(1→4)?−?−?????????????[side]
An unknown trisaccharide was treated with dimethyl sulfate which adds a methyl group to every free OH group. It was then subjected to acid hydrolysis (to break glycoside bonds). The products were 23, 4, 6-tetra-O-methylgalactosc, 23,4-ui-O methyl glucose, and 2,3.6-tri-O methylglucose. Treatment of the intact trisaccharide with 0(1 6)-gaiactosidase yielded galactose and a saccharide. Treatment of this disaccharide with a(l 4)-glucosidase yielded D glucose. Draw the structure of this trisaccharide and give its systematic name.
Identify the structures shown as glycerophospholipids or sphingolipids.
In 3 sentences, explain this. Discuss the difference between an ⍺-D-glucose and a β-D-glucose. How can the structure of a monosaccharide affect its bioactivity?

Please answer both of the following 1) The Haworth projection of D-altrose is shownWhat type of cyclic sugar is formed? 2)Which of the following statement is true about the quaternary structure of aprotein? only one answer is correct
What are the glycosidic linkages of the trisaccharide shown? α1→6, α1→6 α1→6, β1→6 α1→6, β1→5 α1→6, α1→5
Although the first two carbons of fructose and glucose are identical in structure to DHAP and GADP (from glycolysis), DHAP and GADP equilibriate on their in solution to favor the ketone over the aldehyde, while fructose and glucose do not. Why? a)The larger size of the molecule sterically hinders the isomerization b)The larger sugars have more OH groups which hydrogen bond and disrupt isomerization c)The larger sugars cyclize, and there is no carbonyl to isomerize in the cyclic form d)The larger sugars cyclize, and in the cyclic form the hydrogen bonding is very strong e)The larger sugars are less soluble in water than the smaller sugars

J. a monosaccharide under aldopentoses K. a disaccharide consisting of 2 glucose units linked by B(1-4) glycosidic bond
The structure below shows that of a trisaccharide that is composed of (going from top left to bottom right) galactose, glucose, and fructose. More specifically, the component monosaccharides are [D-galactose, L-galactose], [D-glucose, L-glucose], and [D-fructose, L-fructose] .
