The below mentioned article provides a short note on the Nitrogen Balance in Diet. Nitrogen balance is defined as the quantitative difference between the nitrogen intake and the nitrogen output, both expressed in gms N/day. Intake means the nitrogen of the food and output means the excretion of nitrogen as urine, feces, milk, sweat, vomiting, menstrual fluid and loss of [...]
The following points highlight the top seven processes helping amino acids to form succinyl-CoA. The processes are: 1. Methionine 2. Trans-methylation 3. Leucine 4. Valine 5. Isoleucine 6. Catabolism of Histidine 7. Metabolism of Glycine. Amino Acids Forming Succinyl-CoA: Process # 1. Methionine: a. Methionine is first activated by ATP forming S-adenosylmethionine ("active methionine"). b. After removal of the methyl [...]
In this article we will discuss about the Biosynthesis and Catabolism of Amino Acids. Biosynthesis of Amino Acids: Plants and bacteria can form all 22 amino acids from amphibolic intermediates. But humans and other animals cannot synthesize some of these. Therefore, these are supplied by the diet and are termed nutritionally essential amino acids. The remainders are synthesized in the [...]
