Mark all true statements 1 proteins are usually composed of

Mark all true statements 1. proteins are usually composed of a mix of L and D amino acids 2. all amino acids share common structural features and can be differentiated by their specific R group 3. because enzyme active sites are symmetric, the reactions they catalyze are racemic 4. protein chains usually consist of either purely hydrophobic or hydrophilic amino acids 5. almost all amino acids have two possible sterioisomers

Solution

Ans). 2. all amino acids share common structural features and can be differentiated by their specific R group
