Question

那些字母代表在化學性質的

4組分類 昰指蛇麼東西押

哪4類呢

Answer 1

Favorite Answer

The amino acids are arranged into four groups based on the character of their side chains

*Polar charged 極性帶電 =>

Aspartic acid (D)

Glutamic acid (E)

Lysine (K)

Arginine (R)

Histidine (H)

*Polar uncharged 極性不帶電 =>

Serine (S)

Threonine (T)

Glutamine (Q)

Asparagine (N)

Tyrosine (Y)

*Nonpolar 非極性 =>

Alanine (A)

Valine (V)

Leucine (L)

Isolucine (I)

Methionine (M)

Phenylalanine (F)

Tryptophen (W)

* Side chain with unique properties 特殊基團鍵結 =>

Glycine (G)

Cystine (C)

Proline (P)

Answer 2

看不懂題目ㄟ

4類應該是

極性,非極性,酸性,鹼性吧~

Answer 3

有點看不懂ㄋㄟ~

(依極性分類):

非極性胺基酸:Ala.Val.Leu.Ile.Met.Gly.Phe.Try.Pro

極性胺基酸:

不帶電:Ser.Thr.Cys.Asn.Gln.Tyr

帶正電:Lys.Arg.His

帶負電:Glu.Asp

(依特色分類):

-OH:Ser.Thr.Tyr

-S:Cys.Met

-acid group:Arg.Lys.His

-aromatic group:His.Phe.Try.Trp

PI值最高:Arg
