Which amino acid contains sulfur atoms that form covalent disulfide bonds in its tertiary structure?
Cysteine forms disulfide bonds
Peptide bonds form when the amine group of one amino acid combines with the organic acid group of another amino acid?
A peptide bond. Although some amino acids can form other bonds depending on their R groups (cysteine can form a disulfide bond with another cysteine... forming a cystine).
What is the relationship between carbon skeletons and functional groups?
Both carbon skeletons and functional groups put together, add, or have atomos of oxygen, hydrogen, and carbon. Different arrangements of atoms bonded to a carbon skeleton can form functional groups, wich give specific properties to molecules.
What kind of elements form ionic bonds with nonmetals?
Metals. The two most reactive groups of metals that readily form these bonds with nonmetals are the alkali metals and the alkaline earth metals. Groups 1A and 2A.
Which two functional side groups are included in the straight-chain form of all monosaccharides?
Attached to all straight chain forms of monosaccharides are side groups. The side groups are one carbonyl functional group and one hydroxyl group on the remaining carbon atoms.
Which amino acid contains sulfur atoms that form covalent disulfide bonds in its tertiary structure?
Cysteine forms disulfide bonds
What type of bond can two cysteine form?
Disulfide bonds
Is carbon disulfide ionic bond?
No. Carbon does not form ionic bonds, and in this case they are double-covalent bonds.
Why hairs can be straightened or curled with heat or chemical treatment?
When heat or chemicals are applied to the proteins in hair, the disulfide bonds of cysteine units are broken in the polypeptide structures of the hair proteins. The protein can then be straightened or curled, and then the disulfide bonds form again, locking the protein in that conformation.
Peptide bonds form when the amine group of one amino acid combines with the organic acid group of another amino acid?
A peptide bond. Although some amino acids can form other bonds depending on their R groups (cysteine can form a disulfide bond with another cysteine... forming a cystine).
What is the importance of native amide bonds?
Native amide bonds take part in formation of a peptide. If the amine and carboxylic acid functional groups in amino acids join together to form amide bonds, a chain of amino acid units is formed, thus called the peptide bonds.Ê
Functional group links amino acids together to form proteins?
Peptide bonds.
Where can macromolecules be found?
Two molecules in living things that form hydrogen bonds are DNA and protein. Hydrogen bonds form between the two strands of DNA and form when a protein is being folded into its final conformation.
What is the relationship between carbon skeletons and functional groups?
Both carbon skeletons and functional groups put together, add, or have atomos of oxygen, hydrogen, and carbon. Different arrangements of atoms bonded to a carbon skeleton can form functional groups, wich give specific properties to molecules.
What kind of elements form ionic bonds with nonmetals?

Identify a functional group always present in amino acids?
Two functional groups are found in all amino acids. These functional groups are the amino group (-NH2) and the carboxyl group (-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.
Which two functional side groups are included in the straight-chain form of all monosaccharides?
Attached to all straight chain forms of monosaccharides are side groups. The side groups are one carbonyl functional group and one hydroxyl group on the remaining carbon atoms.
