58 grams of protein (The adult RDA for protein is 0.8 grams of protein per kilogram body weight.
To calculate an adult RDA for protein, multiply the weight in kilograms by 0.8. )
The process of removing the amino acid group from the amino acid is called what?
deamination, When an amino acid is used as energy and metabolized to create ATP, the amino acid has to get rid of the nitrogen (or amine) group.
The stomach acid causes this to happen to a protein.
The protein is denatured in the stomach by stomach acid
Our body can make non-essential amino acids using this process.
Transamination
During this process, a new protein is built by connecting amino acids using peptide bonds.
Translation

What of the following is a characteristic of soluble fiber?
helps with stool regularity and regulates blood sugar levels
What is the difference between insoluble fiber and soluble fiber? name examples of both
The main difference between soluble and insoluble fiber is how they interact with water and how they affect digestion.Insoluble fiber examples include : vegetables, wheat bran, and whole grains. soluble fiber examples include : fruits vegetables and oat grains
How will you solve this problem : Harpers dietary intake is 250 carbs, 70 protein, 30 fat. what % comes from carbs.
4 grams x 250, 4 x 70, 30 x 9 = then add those all up which gives you 1550 calories. You will then divide the calories from carbs (1000) by the total calories (1550) to get the percentage which is 65%
