Amino Acids: The Building Blocks for Proteins Flashcards
differ from one another by their R-groups
amino acids
how many common of standard amino acods are there
20
are divided into four groups based on
the properties of R-groups
Standard amino acids
Standard amino acids are divided into four groups based on the properties of
R-groups
R-groups that are non-polar
Non-polar amino acids:
Such amino acids are hydrophobic
Non-polar amino acids:
8 of the 20 standard amino acids are
non polar
how many standard amino acids are non polar
8 of the 20
they are located in the
interior of protein where there is no polarity
Non-polar amino acids:
R-groups that are polar
Polar amino acids:
3 types of Polar amino acids:
Polar-neutral
Polar acidic
Polar basic
contains polar but neutral side chains
Polar-neutral
Seven amino acids belong to this category
Polar-neutral
how many amino acids belong in Polar-neutral
Seven amino acids
Contain carboxyl group as part of the side chains
Polar acidic
Two amino acids belong to this category
Polar acidic
how many amino acids belong in Polar acidic category
Polar acidic
Contain amino group as part of the side chain
Polar basic
how many amino acids belong in the Polar basic category
Two amino acids
Astandard amino acid needed for protein
synthesis that must be obtained from dietary sources
Essential Amino acid:
adequate
amounts of Essential Amino acid: cannot be
synthesized in human body.
