Khi thủy phân tripeptit: $\large H _{2} N - CH \left( CH _{3}\right) C

Khi thủy phân tripeptit: $\large H _{2} N - CH \left( CH _{3}\right) CO - NH - CH _{2}- CO - NH - CH _{2}- COOH$ sẽ tạo ra các $\Large \alpha$-amino axit nào? 

• A. $\large H _{2} NCH _{2} COOH , CH _{3} CH \left( NH _{2}\right) COOH .$
• B. $\large H _{2} NCH \left( CH _{3}\right) COOH , H _{2} NCH \left( NH _{2}\right) COOH .$
• C. $\large H _{2} NCH _{2} CH \left( CH _{3}\right) COOH , H _{2} NCH _{2} COOH .$
• D. $\large CH _{3} CH \left( NH _{2}\right) CH _{2} COOH , H _{2} NCH _{2} COOH .$

Chọn A

$\large H _{2} N - CH \left( CH _{3}\right) CO - NH - CH _{2}- CO - NH - CH _{2}- COOH +2 H _{2} O$

$\large \stackrel{ H ^{+}}{\stackrel{\longleftarrow}{\longrightarrow}} 2 H _{2} NCH _{2} COOH +CH _{3} CH \left( NH _{2}\right) COOH$
