13. Amino Acids: definition - building blocks of proteins
and structure - structure =
> central carbon atom
> Hydrogen atom
> Amino group
> Acid group
> side chain
14. Essential Amino Acids - histidine, isoleucine, leucine, lysine, methionine, phenylalanine,
threonine, tryptophan, valine
- Amino acids that are needed, but cannot be made by the body; they
must be eaten in foods
15. nonessential amino acids - amino acids that the body can synthesize
- Alanine, Arginine, Asparagine, Aspartic Acid, Aspartic Acid (aspar-
tate), Cysteine, Gluatonic Aicd (glutamate), Glutamine, Glycine, Pro-
line, Serine, Tyrosine
