Understanding the Spanish Flu Virus

Characterization of the Reconstructed 1918 Spanish Influenza Pandemic Virus (NOT OPEN ACCESS) SUMMARY: Influenza viruses require a proteolytic enzyme (an enzyme that can cut or cleave proteins), like trypsin, in order to activate a surface protein that allows them to attach/infect our cells. Since viruses can only replicate inside cells, having this proteolytic enzyme is… Continue reading Understanding the Spanish Flu Virus

Metabolizing Acetaldehyde

Acetaldehyde production and metabolism by human indigenous and probiotic Lactobacillus and Bifidobacterium strains. (NOT OPEN ACCESS) SUMMARY: In order to turn ethanol into acetaldehyde, the enzyme alcohol dehydrogenase requires both a zinc atom and NAD+. This study looks at the levels of NAD+ in Lactobacillus and Bifidobacteria after incubating them in ethanol and acetaldehyde, in… Continue reading Metabolizing Acetaldehyde
