BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Amino acids are colourless, crystalline solids. They are soluble in water and solubility varies with R-group of amino acid. They have sharp and low melting points.

Detailed explanation-2: -function in. Copper-containing proteins called hemocyanins occur notably in the blood of larger crustaceans and of gastropod and cephalopod mollusks. Hemocyanins are colourless in the reduced, or deoxygenated, state and blue when exposed to air or to oxygen dissolved in the blood.

Detailed explanation-3: -So, the correct option is ‘Lysine and arginine are acidic amino acids. ‘

Detailed explanation-4: -Amino acids are colourless and can be separated and identified by chromatography. What additional apparatus is required to identify the amino acids present in a mixture? The diagram shows the diffusion of hydrogen chloride and ammonia in a glass tube. The gases are given off by the solutions at each end of the tube.
