A protein consisting of more basic amino acids such as ----------exists as a cation at the physiological pH of 7.4. Such proteins are called basic proteins.
Options
- ALysine and aspartic acid
- BMethionine and arginine
- CLysine and arginine
- DProline and cysteine
Correct answer
C. Lysine and arginine
Step-by-step solution
Basic amino acids contain an extra amino group in their side chain, which gets protonated at the physiological pH of to form a cation.
Examples of basic amino acids include lysine, arginine, and histidine.
Therefore, a protein consisting of more basic amino acids such as lysine and arginine exists as a cation at physiological pH and is called a basic protein.
Answer: Lysine and arginine
Examples of basic amino acids include lysine, arginine, and histidine.
Therefore, a protein consisting of more basic amino acids such as lysine and arginine exists as a cation at physiological pH and is called a basic protein.
Answer: Lysine and arginine
