Chapter 15, Problem 12RQ

Summary Introduction

To review:

The difference between the general scheme of biosynthesis of amino acids and fatty acids.

Introduction:

Most free-living bacteria and plants are capable of making all standard amino acids and genetic codebases along with non-standard variants used in cell walls and RNA. The synthesis of amino acid and nitrogen bases requires energy reduction inputs of significant amounts. The carbon skeleton of amino acids originates from different metabolism intermediates. Microbes receive these molecules from their environment by means of embedded membrane transporters where possible.
