The name of the tetrapeptides abbreviated as S-F-G-Y and Y-F-G-S is to be stated in words. The N-terminal amino acid in each tetrapeptide is to be stated. Concept introduction: The amino acids are the building blocks of protein molecules. The amino acid contains amino group ( − NH 2 ) , a carboxylic acid group ( − COOH ) and side chain ( − R ) . When proteins are broken down, amino acids are produced.

Question

Using the following two half-reactions, determine the pH range in which $NO_2^-\ (aq)$ cannot be found as the predominant chemical species in water.* $NO_3^-(aq)+10H^+(aq)+8e^-\rightarrow NH_4^+(aq)+3H_2O(l),\ pE^{\circ}=14.88$* $NO_2^-(aq)+8H^+(aq)+6e^-\rightarrow NH_4^+(aq)+2H_2O(l),\ pE^{\circ}=15.08$

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Interpretation Introduction

Interpretation:

The name of the tetrapeptides abbreviated as S-F-G-Y and Y-F-G-S is to be stated in words. The N-terminal amino acid in each tetrapeptide is to be stated.

Concept introduction:

The amino acids are the building blocks of protein molecules. The amino acid contains amino group (−NH2), a carboxylic acid group (−COOH) and side chain (−R). When proteins are broken down, amino acids are produced.
