Listing a protein’s amino acids is easy. Machines to do so have existed for decades.But this is only half the battle in the quest tounderstand how proteins work. What a protein does, and how it does it, depends also on how itfolds upafter its creation, into its final, intricate shap...
14-3-3 proteins were the first signaling molecules to be identified as discrete phosphoserine/threonine binding modules. This family of proteins, which includes seven isotypes in human cells and up to 15 in plants, plays critical roles in cell signaling events that control progress through the ...
Can proteins or fats be used for producing energy. Explain. How do proteins work? How does their structure influence their properties? What is the purpose/function of Proteins? Briefly describe three different roles of proteins in your body, and name one type of food that you eat that has ...
How do receptor proteins work? How and when does protein contribute to energy metabolism? Describe how a cell produces and releases proteins. Why does a human body need proteins? Why do the cells have to synthesize proteins when we can get p...
How Cells Work Proteins A protein is any chain of amino acids. An amino acid is a small molecule that acts as the building block of any protein. If you ignore the fat, your body is about 20-percent protein by weight. It is about 60-percent water. Most of the rest of your body is...
Proteins are of different types, and almost every item that you eat contains one or the other type of protein. However, the amount of protein may vary, making your diet protein-rich or protein poor. You will get casein and whey protein by consuming milk and yogurt. Similarly, eggs contain...
Enzymes are made from amino acids, and they are proteins. When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape. That shape allows the enzyme to carry ...

The proteins in your body are constantly repaired and replaced. That means you need to keep eating foods with protein, containing essential amino acids, to keep your body working as it should. Protein is especially crucial when the body is growing or has extra work to do, such as during ch...
