Preparative enzymatic synthesis of several unusual hexoketose and hexoaldose derivatives using fructose bisphosphate aldolase and glucose isomerase as catalysts has been developed. Fructose bisphosphate aldolase catalyzes a stereospecific aldol condensation between dihydroxyacetone phosphate and a number of aldehydes to form ketose 1-phosphates which upon(More)
On the basis of their aims, the Deutsche AIDS-Hilfe focuses on lifestyle-oriented structural prevention and health promotion as well as the continuously changing (social, cultural, sexual, medical, etc.) conditions. In doing so, they stress the collective responsibility of the local AIDS service organizations and of other agents involved in prevention as(More)
Die Deutsche AIDS-Hilfe richtet ihre Arbeit am Ansatz der lebensweisenorientierten strukturellen Prävention und Gesundheitsförderung und an den sich ständig wandelnden (epidemiologischen, medizinischen, sozialen, politischen, kulturellen usw.) Bedingungen aus. Dabei betont sie die gemeinsame Verantwortung der AIDS-Hilfen, anderer Akteure in der Prävention(More)
This paper repofts kinetic parameters (K., fto,) for reduction of approximately 20 a-keto acids by t--lactate dehydrogenase (I--LDH; EC from 5 sources (porcine heart, rabbit muscle, chicken liver, bovine heart,lobster tail). The I-LDH-catalyzd reduction reaction of four substrates representative of the range of act ivi t ies observed has been carr(More)
