Easy Practice — Set 2

Quick Recap — Structures, Bonds & Deficiencies

• Reducing sugars (free anomeric $-CHO$/$-C=O$): glucose, fructose, maltose, lactose; sucrose is non-reducing.
• Glycosidic bond joins monosaccharides; peptide bond joins amino acids; nucleotides link via phosphodiester bonds.
• Protein structure: 1$^\circ$ (sequence), 2$^\circ$ ($\alpha$-helix/$\beta$-sheet, H-bonds), 3$^\circ$ (folding), 4$^\circ$ (subunits).
• Vitamin deficiencies: B$_1$ beri-beri, C scurvy, D rickets, K poor clotting, A night blindness.
