AMINO ACIDS: THE BUILDING BLOCKS FOR PROTEINS

Question 1

is a naturally occurring, unbranched polymer in which the monomer
units are amino acids

Answer 1

Protein

Question 2

is an organic compound that contains both an amino (! NH2) group and
a carboxyl (! COOH) group.

Answer 2

amino acid

Question 2

amino acids are grouped
according to side-chain polarity those are?

Answer 2

nonpolar
amino acids, polar neutral amino acids, polar acidic amino acids and polar
basic amino acids

Question 3

is an amino acid in which the amino group and the carboxyl group are
attached to the !-carbon atom. The general structural formula for an !-amino acid is

Answer 3

a-amino acid

Question 3

is one of the 20 a-amino acids normally found in proteins

Answer 3

standard amino acid

Question 4

is an amino acid that contains one amino group, one
carboxyl group, and a nonpolar side chain.

Answer 4

nonpolar amino acid

Question 5

is an amino acid that contains one amino group, one
carboxyl group, and a side chain that is polar but neutral.

Answer 5

polar neutral amino acid

Question 6

is an amino acid that contains one amino group and
two carboxyl groups, the second carboxyl group being part of the side chain

Question 7

is an amino acid that contains one amino group and
two carboxyl groups, the second carboxyl group being part of the side chain

Answer 7

polar acidic amino acid

Question 8

is an amino acid that contains two amino groups and
one carboxyl group, the second amino group being part of the side chain

Question 11

is an amino acid needed in the human body that must be obtained from dietary sources because it cannot be synthesized within the body from other substances in adequate
amounts

Answer 11

essential amino acid

Question 12

the essential amino acids in approximately the same relative
amounts in which the human body needs them

Answer 13

complete dietary protein
