Protein Definition and 165 Threads

I've adopted a Vegetarian diet and I'm wondering about Protein Powder and Beef Powder. I'm assuming Protein Powder does not contain meat, but does Beef Powder? I was looking at a package of Vegetarian bacon which listed beef powder as an ingredient.

How much protein should I be getting within the 2-3 serving a day suggestion? I've eliminated meat from my diet and am using alternatives. I've heard Eggs are a poor substitute in low amounts and I'd prefer to avoid daily Tofu consumption. Peanut butter and milk supposably have protein - or...

Membrane proteins are integrated into the ER membrane by means of protein translocators, which are themselves membrane proteins. So how would the first protein translocators become incorporated into the ER membrane? Nautica

Hi. What prevents proteins from falling out of cell membranes? This question has been bothering me for sometime... and I cannot find an answer to this. Please help :-p

My textbook’s explanation for spontaneous renaturation of defolded protein is this: “Although in defolded state protein has grater entropy, greater degree of disorder, it folds into original conformation (lower entropy), and this seems to be in collision with the II law of thermodynamics. But...

I need to write a summary paragraph on Protein Synthesis. So far, this is what I have written: The purpose of protein synthesis in gene expression is fundamental to who we are. DNA within a cell codes for protein synthesis. This protein synthesis is facilitated by messenger RNA strands...

If one had no way of eating any protein, but could eat carbohydrates and something which had nitrogen that wasn't a protein, could their body assemble proteins to use, or does that mechanism not exist?

Biochem help :(?? Hi :smile: I have seen great people on this forum, can anybody please help me with this question? Q- The majority of cellular proteins and RNA are synthesized throughout the cell cycle and are only interrupted briefly during M phase. Synthesis of which of the following...

Humans eat cows so we can grow (you need protein to grow). If cows are just eating grass all the time, how are they able to grow? Many people in third world countries are sick because they don't have enough protein in their diet. Cows don't eat meat at all but they don't have that problem...

Hand-to-Hand Model for Tropomyosin Fast Diffusion. Semiconductor Mechanism for Diffusion of Tightly-Binding Proteins: http://actomyosin.narod.ru/h2h-model.htm Would you be so kind as to recommend me some expert who could be interested in view a possible semiconductor mechanism for...

I am trying to do this protein alignment assignment for my Biotech class and I'm having trouble interpreting the results. I used the Blast program at [PLAIN]www.ncbi.nlm.nih.gov/blast/bl2seq/bl2.html[/URL] and have to answer the following questions: What are "Query" and "Sbjct"?, What do the...

The following is the abstract to an article by Joan Emma Shea et al published in journal of chemical physics volume 113 number 17, 1 nov 2000 "The amino acid sequence and the folding motif are essential in determining the protein folding mechanism. The interplay between energetic...

Does anybody have any good links on protein symmetry?
