How many amino acids could be found in the human body?

Answer 1

There are twenty common protein amino acids in your body, of which half can be formed in the cells. The remainder need to be consumed in our diet, as our body cannot make them, yet they are still vital. There are 2 other amino acids very ocassionally used in proteins (only one in humans) meaning that are 21 different protein amino acids in humans.

Some biological pathways use other types of amino acids not found in proteins. There are at least six additional ones found in humans, but it would be difficult to determine an exact number.

Answer 2

There are 20 amino acids found in humans.

9 of the 20 standard amino acids are called "essential" amino acids for humans because they cannot be created from other compounds by the human body, and so must be taken in as food. Others may be conditionally essential for some ages or medical conditions.

Answer 6

Answer 7

All proteins are formed from combinations if only 20 different amino acids

Answer 8
