Question

Equation for the formation of the second tripeptide??

Explanation / Answer

H3C.........NH2 ................| .........CH-CH-COOH [Val] + ......../ H3C ............NH2 ............| + CH3CH-COOH [Ala] ---> H3C.........NH2..........CH3 ............. ...|.................| ........CH-CH-C-NH-CH-COOH [Val-Ala] ......../..............|| H3C..............O + H2O Now take this dipeptide (Val-Ala), and react it with Serine: H3C.........NH2..........CH3 ............. ...|.................| ........CH-CH-C-NH-CH-COOH [Val-Ala] + ......../..............|| H3C..............O .................NH2 .................| HOCH2-CH-COOH [Ser] ---> H3C...NH2...........CH3.........CH2OH.… .....|......|..................|......… ..HC-CH-C-NH-CH-C-NH-CH-COOH .....|...........||.................|| H3C........O................O + H2O Hope that helped!
