生化记忆（Biochemical memory） Biochemical memory Biochemical memory (original) Main reference book: Huang Xitai, Yu Wen, Li Cuifeng. Modern biochemistry 1., the absorption of amino acids in the ultraviolet region: tyramine, benzene, the maximum absorption wavelength decreased (rote, bar, cheese, benzene)! Tyramine is the three aromatic amino acid 2. amino acid single character abbreviation memory method: color cheese (Trp, Tyr, Phe benzene), Im going crazy (W, Y, F); a fine (Lys, Arg), (K, R) cut day; Tiangu Valley (Asp, Glu, Asn, Gln), but you (your dad D, E, NB, QZ), even it is: color cheese benzene, I want a fine day; cut; Tiangu Valley, but your father beat you! The remaining single character is the first letter of the three character. 3. according to the classification of proteins of two level structure, can be divided into alpha, beta, alpha + beta and alpha / beta four types, including alpha + beta and alpha / beta confusing alpha + beta refers to the alpha helix and beta folding independently; alpha / beta refers to the alpha helix and beta folding phase, a one is independent, one is white, can this memory: poison eliminating traitors. The plus sign is independent, division is white. 4. lack of cysteine and tryptophan in collagen. See follow description. 5. immunoglobulin heavy chain has five kinds: alpha, gamma, Delta, epsilon, mu, respectively, composed of IgA, IgG, IgD, IgE, IgM, can be so memory: by alpha, gamma, Delta, epsilon, and muon pronunciation, that is, A, G, D, E, M. (epsilon is E, it may be a little out of the way, but good to remember) 6. three DNA two chain chain chain clip a purine pyrimidine, not two purine chain clip a pyrimidine chain, can memory: two with a single double ring, the ring number balance, ha ha, the similar structure can also remember: histidine bond the number of balance. The reason why there is no 7.DNA in U: you can remember like this: two if..., that is, if... Then.. 8. I, II, III restriction enzyme characteristics: three of
