How Do You Spell GRAMICIDIN A?

Pronunciation: [ɡɹˈamɪsˌɪdɪn ˈe͡ɪ] (IPA)

The word "Gramicidin A" is spelled with the use of the International Phonetic Alphabet (IPA) transcription. The pronunciation is as follows: /ɡræmɪˈsaɪdɪn/ - with the stress on the second syllable. The word is composed of three syllables, starting with a consonant sound followed by two syllables that consist of vowel sounds. Gramicidin A is an antibiotic, initially obtained from the bacterium Bacillus brevis. This potent antibiotic is used in treating bacterial infections and is effective against Gram-positive bacteria.

GRAMICIDIN A Meaning and Definition

1. Gramicidin A is a naturally occurring peptide antibiotic that consists of a cyclic decapeptide loop and is produced by certain strains of the bacteria, Bacillus brevis. It is primarily known for its antimicrobial properties and is commonly used in medicine and research.

   Gramicidin A acts by disrupting the structure and function of microbial cell membranes. It forms channels within the lipid bilayer of the cell membrane, which causes an increase in its permeability. This ultimately leads to the leakage of vital cellular components and the failure of cellular processes, resulting in the death of the target microorganisms.

   Due to its potent antimicrobial activity, gramicidin A has found widespread application in the pharmaceutical industry. It is used in topical preparations such as creams, ointments, and eye drops to treat superficial bacterial infections, particularly those caused by Gram-positive bacteria. Additionally, it is often utilized in laboratory research as a tool to investigate membrane structure and function.

   Gramicidin A has been extensively studied and its structure has been well characterized. It is an important component of the class of peptides known as ionophores, which are able to transport ions across biological membranes. The discovery and understanding of gramicidin A have contributed significantly to the development of antibiotics and our knowledge of microbial membrane physiology, making it a valuable resource in the field of medicine and scientific research.

Etymology of GRAMICIDIN A

The word "Gramicidin A" is derived from "gram-" and "cidin".

The prefix "gram-" comes from the Danish bacteriologist Hans Christian Gram, who developed the Gram stain, a method used to categorize bacteria into Gram-positive and Gram-negative based on their cell wall composition.

The suffix "-cidin" is commonly used in the naming of antibiotics to indicate that it has bactericidal (kills bacteria) properties.

Therefore, "Gramicidin A" refers to an antibiotic that is effective against Gram-positive bacteria, reflecting its ability to kill this type of bacteria.

Plural form of GRAMICIDIN A is GRAMICIDIN AS
