Nêu cảm nghĩ của bạn về đề kiểm tra toán cuối kì đi. _____ HOCH₂–CH(OH)–CH(OH)–CH(OH)–CH(OH)–CH₂OH (glucose), dai như phản ứng xà phòng hóa CH₃(CH₂)₁₄COOH NaOH → CH₃(CH₂)₁₄COONa H₂O, mãnh liệt như 2Na 2H₂O → 2NaOH H₂↑, dịu dàng như Cu(OH)₂ gặp dung dịch HOCH₂–(CHOH)₄–CH₂OH tạo màu xanh lam, day dứt như C₄₉H₇₄O₁₄ phân hủy thành C₁₇H₂₁NO₄ C₁₈H₂₁NO₃ C₁₄H₂₃NO₃, và bền bỉ như quá trình hô hấp C₆H₁₂O₆ 6O₂ → 6CO₂ 6H₂O năng lượng (ATP). Tình anh rối rắm như chuỗi peptit Gly–Ala–Val–Leu–Phe–Thr–Trp–His–L
