Question
Choose the correct structure for the form of the amino acid alanine that exists at the pH values given H3N-CH-COOHH3N-CH-Co0 H2N -CH-COO 1 CH3 2 CH3 3 CH3 major form at pH 2 major form at pH7 major form at pH 12 Check Choose... Choose... Choose... Proteins are responsible for a largest range of functions of all biomolecules. Choose the type of protein to match the described protein function given maintain reservoirs for required metals, nitrogen, other required compounds bind and carry specific molecules or ions from place to place control cellular activity, signalling, and responses protect against invaders and damage response allows movement and changes in shape Catalyze the synthesis and utilization of proteins, carbohydrates, lipids, and nucleic acids and other biomolecules. Choos.. maintain the physical shape and give strength to structures in organisms Choose Choose Choose Choose Choose Choose CheckExplanation / Answer
1. major form at pH = 2 most stable acidic form. so form 1.
major form at pH= 7 zwitter ions form, so form present = 2
major form at pH =12, the most stable basic form, anionic form, so form present = 3
