Amino acids are linked together by:
Correct answer: C. Peptide bonds
- A. Hydrogen bonds
- B. Ionic bonds
- C. Peptide bonds
- D. Glycosidic bonds
Explanation
Amino acids are linked together by peptide bonds. A glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate molecule to another group, which may or may not be another carbohydrate. Hydrogen bonds occur in inorganic molecules, such as water, and organic molecules, such as DNA and proteins. Ionic bonds can also be found in proteins.

About Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their function depends on primary, secondary, tertiary and quaternary structure. The topic covers fibrous and globular proteins, enzymes, antibodies, hormones and transport proteins, as well as denaturation by heat or extreme pH.
