What is the function of polypeptide chains?

Answer 1

what is the Purpose of Protein

Protein is necessary for the building and repair of body tissues.
It produces enzymes, hormones, and other substances the body uses.
It regulates body processes, such as water balancing, transporting nutrients, and making muscles contract.
Protein keeps the body healthy by resisting diseases that are common to malnourished people.
Prevents one from becoming easily fatigued by producing stamina and energy.
Protein is found in muscles, bone, hemoglobin, myoglobin, hormones, antibodies, and enzymes, and makes up about 45% of the human body. Muscle is approximately 70% water and only about 20% protein. Therefore, increasing muscle mass requires extra water, extra energy in the form of carbohydrates (to maintain the needs of that extra muscle), and a little extra protein.

According to Dr. Dan Benardot, for an athlete increasing muscle mass at an extraordinarily high rate of 1 kg/week (2.2 lbs of extra muscle per week), only 4 extra ounces of meat per day would be needed. In most surveys that have been done on athletes, protein intake from food far exceeds requirements. The generally accepted athlete requirement for protein is between 1.5 and 2.0 grams per kilogram of body weight. Many studies show that athletes commonly consume well over 3.0 grams per kilogram of body weight. Most athletes need slightly more protein than non athletes. However, muscle strength, size, and shape comes from athletic training, not dietary protein intake

Two to three servings of lean meat or alternatives each day should give enough protein to meet requirements.
Vegetarian athletes may need two to three servings of legumes, eggs, nuts, seeds or additional dairy products each day.

Answer 2

This is an overly broad question. Poly just means many, and a peptide is amino acids bonded to one another through amide bonds. Peptides form proteins, which have many different purposes, from catalyzing the oxidation of sulfite to sulfate in your body, to building DNA, to oxidizing methane to methanol, etc....

Answer 3

Polypeptide chains are the building blocks of proteins. They play a crucial role in determining the structure and function of proteins by folding into specific 3-dimensional shapes. These shapes are essential for proteins to carry out their biological functions in the body.

Answer 4

the function of polypetides is that they help the cell grow, they make proteins when they fold and can send messages to other cells and the rest of the body as hormones.

Answer 5

look in your textbook if you have one or ask a science teacher or even your science teacher

Answer 6

They are the main building blocks of life
