In practice, however, there are at least two difficulties with this definition. One technical difficulty is that proteins consist of domains that can be fused and split, and in many cases, homologous relationships characterize protein domains rather than whole proteins. Thus, all operations on ...
We frame central issues regarding determination of protein-level variation and PTMs, including some paradoxes present in the field today. We use this framework to assess existing data and to ask the question, “How many distinct primary structures of proteins (proteoforms) are created from the 20...
it is a complete protein. It’s ideal for those who areallergicto cow’s milk and can't tolerate whey protein, or it can be used as a potential supplement by those who don’t like eating meat. Eggs themselves are a good source of severalvitamins, and many protein powders are fortified...
When discussing gene numbers, we consider protein-coding gene loci rather than the number of transcripts a gene potentially encodes. Non-protein-coding genes are not discussed here, although it has been shown that many regions of the genome that were previously considered inactive or featureless ...
Nowadays, there are many celebrities who are famous for their glamour and wealth rather than achievements and this sets a bad example for young people. To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience....
How many nucleotides would be expected for a gene coding for a protein with 400 amino acids? There is 1 start codon, 3 stop codons, and 64 total codons. How many amino acid codons are there? How many letters of RNA molecules in a sequence does it take to ...
Nutritionally speaking, whole foods contain a diverse mix of nutrients that many protein shakes just can’t replicate, no matter how fortified they are. We’re not just talking about macronutrients like carbohydrates and healthy fats (and, of course, protein), but also micronutrients like vitamins...
You want to understand protein, and not just protein powders. (After all, there’s no magic dust in the protein.) You know protein is important for building muscle, but beyond that there are so many questions, such as: How much protein do you need? How often? And what sources are the...
Poor absorption or permeation of a compound is more likely when there are >5 hydrogen bond donors, the molecular mass is >500, cLogP is >5, and the sum of nitrogen and oxygen atoms in a molecule is greater than 10. Many drugs, however, are exceptions to the rule-of-five, and often...
