All the more recent work on alkaptonuria has... strengthened the belief that the homogentisic acid excreted is derived from tyrosin, but why alkaptonuric individuals pass the benzene ring of their tyrosin unbroken and how and where the peculiar chemical change from tyrosin to homogentisic acid is brought about, remain unsolved problems.
The blood corpuscles take up the atmospheric oxygen in the lungs, and the vital chemical process accordingly depends essentially on the combination of oxygen absorbed by blood corpuscles with the combustible constituents of the blood to form carbonic acid and water.
I wanted a drink. There were a hundred reasons why a man will want a drink, but I wanted one now for the most elementary reason of all. I didn't want to feel what I was feeling, and a voice within was telling me that I needed a drink, that I couldn't bear it without it. But that voice is a liar. You can always bear the pain. It'll hurt, it'll burn like acid in an open wound, but you can stand it. And, as long as you can make yourself go on choosing the pain over the relief, you... Read more »
I palliate the sufferings of others. yes I see myself as softening the blows, dissolving acids, neutralizing poisons, every moment of the day. I try to fulfill the wishes of others, to perform miracles. I exert myself performing miracles.
There is no agreement on the extent to which metabolism could develop independently of a genetic material. In my opinion, there is no basis in known chemistry for the belief that long sequences of reactions can organize spontaneously -- and every reason to believe that they cannot. The problem of achieving sufficient specificity, whether in aqueous solution or on the surface of a mineral, is so severe that the chance of closing a cycle of reactions as complex as the reverse citric acid cycle, for example, is negligible.
