WebbWhat Is Protein? Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way. WebbSimilarly, mRNAs are less stable than proteins (with an average half-life of 2.6–7 hours versus 46 hours, respectively) 5,22. The long half-lives of proteins have been confirmed by independent studies in other systems 17 , 18 and suggest a potentially large role of protein ‘dilution’ — that is, the decrease in protein concentration owing to cell division 17 .
