Verified step by step guidance
1
Understand that amino acids are the building blocks of proteins, and there are a specific number of them that are commonly found in proteins.
Recall that the standard set of amino acids that are encoded by the universal genetic code is what is typically referred to when discussing amino acids in proteins.
Recognize that while there are many amino acids in nature, only a specific number are used in the synthesis of proteins in living organisms.
Consider that the number of standard amino acids is a well-established fact in biochemistry and is a fundamental concept in the study of proteins.
Conclude that the commonly accepted number of standard amino acids found in proteins is 20, which is a key concept in understanding protein structure and function.
