in the tertiary structure of a protein, an electrostatic interaction could form between the r-groups of which two amino acids? a. arg and his b. glu and arg c. gln and lys d. leu and asp e. asp and thr



Answer :

In the tertiary structure of a protein, an electrostatic interaction could form between the r-groups of (b) glu and arg amino acids.

Peptides and proteins are made up of chemicals or building blocks called amino acids. Each amino acid is made up of a tetrahedral carbon, a carboxyl group, and an amino group. The -carbon is the name given to this carbon (alpha-carbon).

The R groups on the side chains of amino acids are what separate them from one another. Each amino acid's R group will have a unique structure, electrical charge, and polarity.

An absolutely necessary amino acid called arginine has a positively charged guanidino group. The active centers of proteins that bind phosphorylated substrates frequently contain arginine because it is ideally suited to bind the phosphate anion.

Protein 1 carries a positive charge on the side chain of the amino acid arginine. Protein 2 has a negatively charged side chain of glutamic acid amino acids. Ionic bonding, or the attractive force between the positive and negative charge, is the most likely interaction between these two amino acids.
