4. Amino acids are weak polyprotic acids. There they will readily form ________ systems which control the pH of a system. a) Give an example of a biological system within the human body that is buffered. b) What is the pH of a glutamic acid solution if the alpha carboxyl group is 1⁄4 dissociated? c) Lysine is an amino acid with a basic side chain. Often, basic side chains accept protons and are thus positively charged. What could you do...

\Match the following descriptions with the corresponding amino acids: This amino acid is responsible for the strength of rhino horns and wood lignin due to the strong hydrophobic interactions between them. Subtle decreases in the serum pH lead to the protonation of this amino acid, which promotes O2 release from hemoglobin. This amino acid is the nucleophile chymotrypsin uses to attack peptide bonds. This amino acid disrupts α-helices because it makes the nearby protein backbone too flexible (and prevents proper...

New life form discovered bottom of the ocean. This life form uses 8 new amino acids to build proteins, with also the 20 that are already use. Also, size of their codons appears the same as ours. Which statements could be expected to be true for this life form? Select one: a. Protein structure will be less diverse b. Genetic code will be more redundant so more of the codons code for the same amino acids c. Must have less...
