Classify each of the amino acids: 2) Choose the pair of words which fill in the blanks in the respective order. a. Sucrose fructose i. Lactase and lactose ii. Sucrase and glucose iii. Maltose and maltase iv. Galactose and amylase b. In the small intestine, proteins are further degraded by up by epithelial cells. Trypsin and oligopeptides ii. Amylase and chymotrypsins

Explanation / Answer

10) drawn below is the structure of tripeptide seryl-alanine-lysine

a) with no change, the peptide at physiological pH exists in zwitterionic form as it is the most stable form of the peptide.

b) Amino acids

alanine : non-polar

lysine : polar basic

2 a. Digestion of sucrose is done to give glucose and fructose,
