Which amino acid is regarded as collector of amino groups?
Aspaate
Arginine
Cysteine
Glutamate
First step in catabolism of amino acids is the transfer of NH3 group from amino acid to Alpha Keto- Glutarate forming Glutamate- known as Transamination. So Glutamate is regarded as collector of amino groups. Note:-The safe non-toxic form of ammonia transpo in blood from most body tissues is Glutamine. Collector is Glutamate, transpoer is Glutamine
