The cell walls of bacteria primarily contain peptidoglycan, which is composed of sugar chains cross-linked by short peptide segments. The amino acids commonly found in these peptide chains include D-alanine, D-glutamic acid, L-lysine (or meso-diaminopimelic acid in some species), and L-alanine. These amino acids contribute to the structural integrity and rigidity of the bacterial cell wall.
What else can I help you with?
Where are amino acids in the cell?
Single amino acids are found in the cytoplasm of the cell. They are mainly useful in protein synthesis, although they have other uses.
Name and briefly describe 4 types of molecules found in a cell?
ATP RNA amino acids proteins including enzymes lipids carbohydrates including sugars
Why is the cell wall of the bacteria called peptidoglycan?
Peptido = amino acid peptide chains. Glycan = sugar The wall is composed, basically of these amino acids and sugars in a mesh like structure.
What part of the cell uses amino acids to build proteins?
All cells synthesize (build) proteins from amino acids. The information that the cell needs in order to arrange the amino acids in the right sequence is stored in DNA.
Which cell organelle put amino acids together in a specific sequence to make proteins?
Ribosomes are the cell organelles responsible for putting amino acids together in a specific sequence to make proteins. They can be found both free in the cytoplasm and attached to the endoplasmic reticulum.
Where are amino acids found in a cell and how are they transported?

Amino acids that are not yet part of a polypeptide are found in which part of the cell?
Amino acids that are not part of a polypeptide are typically found in the cytoplasm of a cell. They are either freshly synthesized by ribosomes or recycled from proteins that have been degraded.

What is peptidoglycan where is it found?
Peptidoglycan is a chemical found in most cell walls of plant cells. Peptidoglycan is a polymer consisting of sugars and amino acids that forms the cell wall.
What part of the cell uses amino acids to build proteins?
All cells synthesize (build) proteins from amino acids. The information that the cell needs in order to arrange the amino acids in the right sequence is stored in DNA.
What would happened if cell did not have a supply of amino acids?
If a cell did not have amino acids or the ability to produce them this would mean that cell did not have the plasma membrane and the membranes that surround a cellâ??s organelles. In this situation a cell would not have the ability to fix damage it sustained or be able to reproduce.
Which cell organelle put amino acids together in a specific sequence to make proteins?
Ribosomes are the cell organelles responsible for putting amino acids together in a specific sequence to make proteins. They can be found both free in the cytoplasm and attached to the endoplasmic reticulum.
How does the amount of ATP affect the concentration of amino acids outside of the cell relative to inside of the cell?
The lower the amount of ATP, especially if there is none present, the concentration of amino acids outside of the cell will be much greater than on the inside, because amino acids need to be aided by a sodium ion. Sodium is pumped outside of the cell (where the amino acids are) by the sodium-potassium pump which needs ATP to function; therefore, if there is no ATP, the pump will not operate, there will be no sodium ions on the outside to aid amino acids into the cell.
Chemical process in a cell?
Metabolism
Where in the cell are the amino acids assembled into proteins?
Proteins are synthesized by ribosomes, which are located on the rough ER as wells as freely within the cell. During translation of protein synthesis, transfer RNA molecules carry amino acids from the cytoplasm to the ribosome to be inserted into the protein being made.Everywhere there are proteins. From the cell membrane to the attendant proteins on the DNA.Amino acids are the monomers of all proteins found in our body and so are found in all protein based structures in all cells in our bodies. Amino acids congregate in the ribosomes of cells during protein production where mRNA (a trancription of DNA) acts as a template to put the amino acids in order.
