Question

enzyme leb ae omio Page 8 33 a. What does the R group in the structure of an amino acid represent? b. If the R group is hydrogen, what amino acid is formed? c. If the R group is a Methyl group (CHs), what amino acid is formed? Read pages ENZYMES: Bnzymes are large complex protein molecules that control the rate of all cal reactions in all living things. Enzymes behave as organic catalysts during the chemical reactions of metabolism. A catalyst is a substance that acts to speed up or slow down the rate of a chemical reaction. Enzymes therefore regulate the rate of chemical onim Enzvmes allow the chemical reactions of metabolism to

Explanation / Answer

33a. R in the amino acid simply represents a aside chain .

It also determines the position of the carbon in a chain (alpha carbon , beta carbon )

R could be a carboxyl group , an an amino group , an hydroxyl group etc .

b) Of there is only one hydrogen atom attached to the carbon atom , it would result in the formation of the simplest amino acid , which is Glycine.

c) If there is a methyl group attached to the amino acid , there will be formation of Alanine .

The same chemical formula goes for serine .
