Why might it be advantageous to add a preassembled block of 14 sugar residues to a protein in the ER rather than building the sugar chains step-by-step on the surface of the protein by the sequential?
The preassembled sugar chain allows better quality control. The assembled oligosaccharide chains can be checked for accuracy before they are added to the protein; if a mistake were made in adding sugars individually to the protein, the whole protein would have to be discarded. Because far more energy is used in building a protein than in building a short oligosaccharide chain, this is a much more economical strategy. This difficulty becomes apparent as the protein moves to the cell surface: although sugar chains are continually modified by enzymes in various compartments of the secretory pathway, these modifications are often incomplete and result in considerable heterogeneity of the glycoproteins that leave the cell. This heterogeneity is largely due to the restricted access that the enzymes have to the sugar trees attached to the surface of proteins. The heterogeneity also explains why glycoproteins are more difficult to study and purify than nonglycosylated proteins.
Which has more sugar 7up or sprite?
Sprite has slightly more sugar than 7Up.
Why is sand more dense than sugar?
Sand is more dense than sugar because sand particles are larger and heavier than sugar particles. This means that there are more mass in a given volume of sand, leading to a higher density compared to sugar.
Is glucose bigger than a protein?
No, glucose is a sugar. And a carbohydrate. Google sugar.

Does semen have more protein than an 8oz steak?
Lets think about that, we are talking about comparing 1/4 ounce of liquid semen ( about 10 grams of protein) to an 8-12 ounce piece of beef ( 80 grams of protein) ..NO SEMEN doesn't come close to the beef! I was amused to find a forum that asked young guys how much semen is in each ejaculation, some thought it was 3-4 ounces.. that's a shot glass X 2! It is a very small amount, 1/2 ounce is a HUGE ejaculation.
Do foods high in sugar give more energy than foods high in protein?
The answer to your question has a lot of variables and depends on the complete diet of the person and their lifestyle. However, the general answer is yes. Sugar is a carboyhdrate and more efficiently metabolized as an energy source than protein.
Is using honey better than sugar?
Both sweeteners contain glucose and fructose. However, for sugar, in the process of manufacturing, the organic acids, protein, nitrogen elements, enzymes and vitamins in the sugar cane are destroyed . So honey is healthier.
What are the benefits of the sperm when its swallowing?
The benefits are a small amount of protein and glucose. Other than that there are no harmful effects of swallowing semen.

Does fat contain more energy than protein?
Protein produces more energy than does fat.
Does urine have more protein than protein shakes?
Urine should certainly not contain more protein in it than a protein shake. If there are too high levels of protein in the urine, it is known as proteinuria.
Which has more crystals salt or sugar?
Based on observing salt is more crystalize than sugar
Why do girls talk more than boys?
Girls talk more than boys due to a certain protein in their brain. The protein is Foxp2 and girls have more of it than boys. This protein is associated with talking.
If your semen is thinner than before can it be due to an std?
No. Thin semen is a result of more fluid being combined with sperm once orgasm occurs. If youre semen is thin, then that usually means you have more fluid than sperm, which usually occurs after multiple orgasms in men.
