Intermediary metabolism of the sialic acids.
The wide distribution and biological importance of glycoproteins and mucins has been stressed a t these meetings. The precise structures of these polymers are not known but are thought to consist of protein backbones and carbohydrate side chains containing hexoses (D-galactose, D-mannose) , a 6-deoxyhexose (L-fucose), S-acetylhexosamines (D-galactosamine and D-glucosamine) , and sialic acids. O...
متن کاملStudies on the Intermediary Carbohydrate Metabolism of Aquatic Animals
1. Liver, kidney, brain, skeletal muscle, and cardiac muscle from one newborn and three adult long-snouted dolphins (Stenella plagiodon) were obtained for enzyme studies. 2. All of the dolphin tissues exhibited cytochrome oxidase, succinic dehydrogenase, and malic dehydrogenase activity. Considerable differences in the enzyme activities of the various tissues were noted, with cardiac muscle exh...
متن کاملThe Metabolism of Amino Acids
It was shown by Seth and Luck (1) that the intestinal absorption of glycine and alanine by rabbits was followed by pronounced aminoacidemia. Other amino acids when administered in similar amounts provoked smaller increases in the amino nitrogen content of the blood. Glutamic acid and aspartic acid were absorbed with but a slight aminoacidemia. The question then arose as to whether these strikin...
متن کاملStudies on myocardial metabolism of protein and amino acids by the use of C14-labelled substrates.
(1) In order to study the relationship between the energy metabolism via TCA cycle and amino acid metabolism as well as protein synthesis, C14-labelled substrates were used for tracer experiment . (2) Considerable C14O2 formation was noted from carbohydrates such as acetate-1-C14, pyruvate-1-C14, and pyruvate-3-C14, while a smaller amount of C14O2 was produced from amino acids such as glycine1-...
متن کاملThe metabolism of "surplus" amino acids.
For an adult in N balance, apart from small amounts of amino acids required for the synthesis of neurotransmitters, hormones, etc, an amount of amino acids almost equal to that absorbed from the diet can be considered to be "surplus" in that it will be catabolized. The higher diet-induced thermogenesis from protein than from carbohydrate or fat has generally been assumed to be due to increased ...
