- There are 20 standard amino acids in proteins
- Among the standard amino acids, 8 are essential (cannot be synthesized in the body and must be supplied on diet) for adults while 10 for children (includes histidine and arginine)
- The L-enantiomer is the naturally occurring form
- The major functional groups in amino acids include:
- α-amino group – basic (alkaline) group
- α-carboxylic group – acidic group
Note: The side chain part of amino acid may contain the above-mentioned functional group or other functional group[/cs_text][/cs_column][/cs_row][/cs_section][/cs_content]
