Draw a β-O-glycosidic linkage between D-glucose and threonine
A disaccharide G is formed from β-D-lyxopyranose and α -D-idopyranose joined by β-1,6'-glycosidic linkage. Draw the structure of β-D-lyxopyranose and α-D-idopyranose Draw the structure and give the IUPAC name of disaccharide G Does disaccharide G mutarotate. Explain your answer.
Part A d-Glucose units joined by beta-1,4-glycosidic linkages are not digestible by humans because o humans lack the enzyme necessary to hydrolyze this linkage O all groups being equatorial in the glucose rings make the chains too stable to digest o it is a glycoside and therefore, indigestible . It is unbranched and therefore, Indigestible O all the above Submit Request Answer Provide Feedback

1 a) Draw the tetrapeptide Ala-Thr-Asp-Asn and indicate the peptide bonds (5 marks) b) Nucleic acids are chains of five-membered-ring sugars linked by phosphate groups. Each sugar is bonded to a base in a β-glycosidic linkage. Draw representative structures of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) indicating the location of the phosphodiester linkage, the β-glycosidic linkage and the key distinguishing feature between DNA and RNA.
