Honey bees are chemists. Using enzymes and dehydration, these scientists of the natural world are able to change the sugar in nectar into a supersaturated power food. It's no small feat-honey is composed of at least 181 components. Its unique taste isa result of complex chemical processes, ...
It is significant that nowadays fiber is considered to be an important part of a healthy diet. In white bread, for example ,the fiber has been removed. But it is present in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet co...

Honey is a natural food produced by honeybees and contained approximately 200 distinct chemical compounds. The chemical compositions are dependent on the floral and geographical origin of the nectar collected by the bee. The physicochemical properties of honey such as moisture content, pH, free acidit...
(毛毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them.The even more astonishing,the tree sent out a special vapour-a signal causing its neighbours to change the chemistry of their own leaves and ...
To become resistant to cationic polymers such as PHMB, a bacterium would need to completely change the chemistry of its membrane, which is unlikely to happen. Xue et al. [89] tested the ability of a highly-branched cationic polymer poly(amidoamine) (PAMAM) in inducing bacterial resistance. ...
A new study highlights differences in the contamination profile of natural toxins found in local and retail honey of Italian and foreign origins.
Better living through chemistry. But a specter loomed – something like the opening of Pandora’s box, or the terrible fury that screamed forth at the opening of the Ark of the Covenant in Raiders of the Lost Ark. World War I did not end all wars and make the world safe for ...
