To review:
The structure of the original oligosaccharide is to be determined that contains twoglucose residues and one galactose residue. It produces two glucose with methoxygroupat 2,3, and 6 position and galactose with methoxy group at 2,3,4, and 6 positions, when exhaustive methylationfollowed by subsequent hydration is performed.

- Question 4. Imagine the main chain of a protein bends back on itself so that two amino acid residues R1 and R2 come close to each other. In the table below are four possibilities for what R1 and R2 might be. In each case, decide whether a specific interaction could form between the residues. If a specific interaction could form, give the name of the interaction. R₁ cysteine tyrosine threonine arginine R₂ cysteine phenylalanine glutamine aspartate specific interaction? OO yes O yes O no no OO O yes no yes no name of specific interaction 0 П 0 0arrow_forwardquestion 1 : draw an α,α(2, 2) linkage between the two monosaccharides(two fructose ). label the glycosidic linkage. Must be Haworth question 2 : Draw glycosidic linkage between D-glucose linked to D-altrose with a β(1, 3) glycosidic linkage. label clearly the glycosidic linkage. must be Haworth.arrow_forwardQuestion 1. a) Explain how 5 specific fatty acids ultimately generate specific classes of prostaglandins and leukotrienes that are involved in blood pressure, platelet aggregation and inflammation.b) Indicate and explain the specific effects of each of these classes of prostaglandins and leukotrienes on blood pressure, platelet aggregation and inflammation.c) Identify which foods, functional foods and nutraceuticals provide one or more of these 5 fatty acids.arrow_forward
