- What is the major biochemical function of each of the following proteins? α-Keratin _____________________________________ Collagen _____________________________________ Hemoglobin _____________________________________ Myoglobin _____________________________________Trade Names of the Pexidartinib (international and national) and write Generic name/ Chemical name:L-Dopa (Levodopa) is an oral medication used to treat Parkinson's disease, the symptoms of which result from a lack of dopamine in the brain. L-Dopa relies on L-type, or leucine-preferring, transport proteins to cross the blood-brain barrier, and it is converted to dopamine in the brain by the enzyme aromatic-L-amino-acid decarboxylase. Properties of L-Dopa: density: 1.47 g/cm • melting point: 278 °C • boiling point: decomposes solubility in water: low solubility • solubility in lipids: low solubility • rotates plane-polarized light counterclockwise Classify each property based on whether it is or is not a property of L-Dopa's enantiomer, D-Dopa.

- Mixtures of amino acids can be analyzed by first separating the mixture into its components through ionexchange chromatography. Amino acids placed on a cation-exchange resin containing sulfonate ( -SO3-) groups flow down the column at different rates because of two factors that influence their movement: (1) ionic attraction between the sulfonate residues on the column and positively charged functional groups on the amino acids, and (2) aggregation of nonpolar amino acid side chains with the hydrophobic backbone of the polystyrene resin. For each pair of amino acids listed, determine which will be eluted first from the cation-exchange column by a pH 7.0 buffer.
