List of MeSH codes D09

• • Teichoic Acids: A Structured Overview**

• • Definition and Origin:**

Teichoic acids are specialized structural components found primarily in the cell walls of gram-positive bacteria. The term "teichoic" is derived from the Greek word "τεῖχος" (teichos), meaning wall, reflecting their role as integral parts of the bacterial cell wall.

• • Chemical Composition:**

These acids consist of long-chain polymers made up of repeating disaccharide-phosphate units. Each unit typically includes a sugar component and a phosphate group, contributing to both structural integrity and functional roles within the bacterial cell wall.

• • Biological Role:**

• • Examples:**

Bacillus subtilis is a notable example where teichoic acids play significant roles in cell wall structure and function.

In summary, teichoic acids are essential bacterial components that combine structural support with functional interactions, primarily found in gram-positive bacteria.
