摘要
禽分枝杆菌C2是两种同源肽糖脂C2a(式III)和C2b(式IV)的混合物，两者都具有以下部分结构:d -丙氨酸的c端分子使真菌苷C2a中的6-脱氧- l- talose和真菌苷C2b中的3- o -甲基-6-脱氧- l- talose的假醛功能酯化。一个乙酰基与3,4-二- o -甲基鼠李糖相连，两个乙酰基与6-脱氧- l- talose和3- o -甲基-6-脱氧- l- talose相连。脂质部分是近似式C43H86O2±3 CH2或C46H90O3±3 CH2的酸(或酸的混合物)RCOOH，通过酰胺键与d -苯丙氨酸的氨基结合。
Mycoside C2 from Mycobacterium avium is a mixture of two homologous peptidoglycolipids: C2a (Formula III) and C2b (Formula IV). Both have the following partial structure:
The C-terminal molecule of D-alanine esterifies the pseudoaldehydic function of 6-deoxy-L-talose in mycoside C2a and that of in mycoside C2b. One acetyl group is linked to 3,4-di-O-methylrhamnose and two acetyl groups to 6-deoxy-L-talose and to .
the lipid moiety is an acid (or mixture of acids) RCOOH of approximate formula C43H86O2 ± 3 CH2, or C46H90O3 ± 3 CH2 bound by an amide linkage to the amino group of D-phenylalanine.
