Summary Introduction

To describe: Tests that can help in determining which versions of lactose having an altered amino acid residue have a significantly altered three-dimensional structure.

Introduction:

Lactase in a digestive enzyme found in the human body. It hydrolyzes a disaccharide called lactose. Lactose is a disaccharide found richly in milk. Its hydrolysis yields two monosaccharides called glucose and galactose. Basically, the proteins are three-dimensional structures that are denoted by the order of the amino acids in its chain. The final conformational folded structure is driven by any polypeptide chain.

Predict the amino acid sequence based on the conditions below. Use the one-letter abbreviation of amino acids. ___1___--_2_- 3 -- --____6_--_7__ a. The amino acid in the C-terminal is optically inactive. b. The fifth amino acid is a neutral aromatic amino acid that yields a negative result for the Xanthoproteic test using intact protein but produces a yellow soln with basic hydrolysate. It also gives a negative result with both Hopkin's Cole and Millon's test using basic hydrolysate. c. After treatment of this peptide with aminopeptidase (specificity: peptide bond on the N-terminus), it yields serine and a hexapeptide d. The amino acid besides the N-terminal amino acid. will yield ornithine and urea after alkaline hydrolysis. e. The third amino acid gives a positive result for Hopkins-Cole Test. f. Chymotrypsin^ cannot cleave the peptide bond on the fifth amino acid because of the presence of this a.a. residue. g. The amino acid at the carboxy-end of the third amino acid will yield a…
