Could alien blood be toxic to us?

Could alien blood be toxic to us? It may seem like a funny question, but it leads to some interesting scientific places! Not surprisingly, the chances that exo-toxicology (the toxicology of extraterrestrial life forms) becomes a critical issue in our lifetimes is small. But with rapid developments

Q 11 Stereoisomerism

Asymmetrical carbon atoms (chirality centers) and thus the stereoisomerism are explained. Using the example of glucose. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

Q 11 Construction of amino acids

The structure of the amino acid molecules is discussed. Due to the different remains, there are 20 naturally occurring AS. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

Q 11 Substrate Saturation Curve

The reaction speed of the enzyme-catalyzed reactions depends on various factors. In this screencast, the dependence on the substrate concept is explained and the curve is derived. Finally, the Michaelis constant is described. Original: "Wolfgang Dukorn" Original: German. All translations in this v

Q 11 Disaccharides

The condensation reaction to the formation of disaccharides is explained. Furthermore, the differentiation of anomera, the reducing effect and mutarotation are briefly discussed. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

Q 11 Mutarotation in glucose

alpha-glucose and beta-glucose are in balance. This can be demonstrated by measuring the angle of rotation of linearly polarized light. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
