Prebiological Formaldehyde Condensation
A definition of the term " l i f e " , if understood as one element in a supposed class of extraterrestrial and prebiological phenomena, is shown to be logically impossible because life is the sole known element of that class. Instead, the properties of the class of "b io ids" , defined as the class of " open systems which can exist in several steady states" (DECKER and SPEIDEL, Chemiedozentent...
متن کاملThe mechanism of the condensation of formaldehyde with tetrahydrofolic acid.
The bell-shaped pH rate profile for the reaction of tetrahydrofolic acid with formaldehyde to form 5, lo-methylene tetrahydrofolic acid has been shown to result from a change in rate-determining step with changing acidity. In alkaline solution, the rate-determining step is the acid-catalyzed dehydration of hydroxymethyl tetrahydrofolic acid and its conjugate base. This step is subject to genera...
متن کاملAction of Formaldehyde on Microorganisms. Iii. Bactericidal Action of Sublethal Concentrations of Formaldehyde on Aerobacter Aerogenes.
Neely, W. Brock (The Dow Chemical Co., Midland, Mich.). Action of formaldehyde on microorganisms. III. Bactericidal action of sublethal concentrations of formaldehyde on Aerobacter aerogenes. J. Bacteriol. 86:445-448. 1963.-Bacteriostatic concentrations of formaldehyde were found to be bactericidal during the initial growth period. This bactericidal activity was due to the primary induction of ...
متن کاملThe stereochemistry at carbon 3 of pyruvate lyase condensation products. Aldolases forming condensation products racemic at carbon 4.
Both the Schiff base-mediated 2-keto-4-hydroxyglutarate aldolase of liver and the metal-activated a-keto-/3-deoxyhexarate aldolase of Escherichia coli condense pyruvate and glyoxylate to form (4-RS)-Z-keto-4-hydroxyglutarate. Both enzymes catalyzed a condensation between [3-3H3]pyruvate and glyoxylate. It was found that C-C synthesis occurred 6 to 7 times faster than C-T bond cleavage. Thus, py...
متن کاملRetention of preservative levels of formaldehyde in desiccated biological products.
Concentrations ranging from 8 to 100% of the preservative level of formalin (37% formaldehyde solution) were retained by desiccated biologics, with most products retaining about 50% regardless of the amount originally present.
