Across
1.one of the stresses that when applied to a protein, can denature it (two words)
6.one of the proteins containing heme group
8.the arrangement of multiple folded protein or coiling protein molecules in a multi-subunit complex (several polypeptide chains) (two words)
13.biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form
14.a process in which a protein has undergone denaturation and loss of solubility by becoming entangled, caused by elevated temperatures
16.a common motif in the secondary structure of proteins (two spelled out words)
22.another common motif in the secondary structure of proteins (three spelled out words)
26.the pH at which a particular molecule or surface carries no net electrical charge (e.g., when a protein is in its zwitterionic form) (two words)
27.the three-dimensional structure of a protein having only one polypeptide chain
28.an oxygen-transport protein
29.a family of fibrous structural proteins that are key structural components of hair and nails (two spelled out words)
30.isomeric molecules that have the same molecular formula and sequence of bonded atoms (constitution), but that differ only in the three-dimensional orientations of their atoms in space
Down
2.a process in which proteins lose their tertiary and secondary structure, which is present in their native state, by application of some external stress
3.the name of the digestive enzymes that break down proteins (two words)
4.amino acids that cannot be synthesized de novo by the organism (usually referring to humans), and therefore must be supplied in the diet (three words)
5.many amino acids linked together
7.the name of the amide bond in polypeptides (two words)
9.a polar, neutral amino acid
10.the structure level defined by the hydrogen bonds of the biopolymer (two words)
11.molecules that serve as the building blocks of proteins (two words)
12.a type of molecule that has a non-superposable mirror image, feature that appears in molecules that contain at least one asymmetric carbon atom (two words)
15.one of two stereoisomers that are mirror images of each other that are non-superposable (not identical)
17.the structure level dictated by the exact sequence of amino acids that comprise the whole molecule (two words)
18.the inactive form of a proteolytic enzyme
19.an autosomal recessive genetic blood disorder characterized by red blood cells that assume an abnormal, rigid shape (three words)
20.the shape of souble proteins (two words)
21.a neutral molecule with equal numbers of positive and negative electrical charges at different locations within that molecule
23.two amino acids linked together
24.one of the twenty DNA -encoded amino acids, which is the only secondary amine
25.a class of amino acids that prefer the contact with one another over the contact with water (hydrophobic molecules)
