Question

Classify these amino acids as acidic, basic, neutral polar, or neutral nonpolar. Drag each item to the appropriate bin. a) Alanine. b) Arginine. c) Glutamine

Answer 1

1) Alanine - Neutral Nonpolar (It is non-acidic)

2) Arginine - Neutral Polar, Basic,

3) Glutamine - Neutral Polar

Step-by-step explanation:

Amino acids:

• Alanine is any of several isomers of a colorless, crystalline, water-soluble amino acid, CH3CH(NH2)COOH, found in many proteins and produced synthetically, used chiefly in biochemical research.
• Arginine is an essential amino acid, C6H14N4O2: the free amino acid increases insulin secretion and is converted to urea in the liver by arginase.
• Glutamine is a crystalline amino acid, HOOCCH(NH2)CH2CH2CONH2, related to glutamic acid.

Definitions:

• Acidic: Acid-forming, yielding acid in chemical reaction; acidic
• Basic: Basic chemicals are chemical that are essential building blocks for other products.
• Polar: Capable of ionizing, as NaCl, HCl, or NaOH; electrolytic; heteropolar
• Non-polar: Containing no permanent dipolar molecules; lacking a dipole.
