classification of amino acids Flashcards
(23 cards)
what is chemical classification?
it’s a classification based on the structure of the side chains (R groups)
what is polarity-based classification?
based on the polarity of the side chain
what is nutritional classification?
based on wether the amino acids can be synthesized or not in the body
what is metabolic classification?
based on the metabolic fate of amino acids in the body
glycine
aliphatic (nonpolar)
alanine
aliphatic (nonpolar)
