The Amino Acid Song [original song]

as i was account through campbell analysis 6th copy at assignment today, i came aloft the area introducing the 20 amino acids, disconnected into nonpolar, polar, and electrically charged. in adjustment to bethink them all i anticipation i would address a absurd little catchword actuality it is:
methionine and tryptophan
and phenylalanine.
isoleucine, glycine then
theres valine,
...these are all nonpolar, man
and proline is as well.
theres addition that ill add,
its leucine, aint it swell?
glutamine and threonine
and cysteine,
these are polar, serine too
as able-bodied asparagine.

now able-bodied see which ones are charged
electrically for you.
glutamic acid is a one
aspartic acid two.
arginine and histidine
are basic; am i wrong?
as is lysine now were done
the amino acid song.
humans can accomplish about bisected of the 20 amino acids in proteins, and yes, the blow are capital amino acids (those which our beef cannot synthesize) that charge be acquired from comestible sources.
the afterward is a account of the capital amino acids:
methionine
valine
threonine
phenylalanine
leucine
isoleucine
tryptophan
lysine
corn (and added grains) accept the aboriginal six; beans (and added legumes) accept all of them except for methionine.
therefore a able-bodied counterbalanced diet of fruits and vegetables that includes grains and legumes, will accord a being all the capital amino acids they need. which of advance means, all the protein they need.
look meat!
