Proteins are polymers of amino acids and they are the most diverse type of biomolecule in your body. Amino acids include 9 essential amino acids, high quality proteins, and 11 non-essential acids. Protein structure follows a specific hierarchy which are primary, secondary, tertiary and quaternary.Roles of proteins
1. Supporting growth and maintenance- structure proteins
2. Building enzymes (speed up reactions), hormones (chemical messengers) and other compounds
3. Transport and recognition proteins
4. Building antibodies( immunoproteins)
5. Maintaining acid base balance( blood proteins as buffers)
6. Maintaining fluid and electrolyte balance
7. Energy
8. Used for energy storage- fat, glycogen
Incomplete/complete proteins
Plant proteins usually are incomplete proteins, usually are low in one or more essential amino acids, but some are exceptions: quinoa, oats and soy are complete protein. Animal proteins have ample amounts of all 9 essential amino acids termed complete or high quality proteins. We have to intake essential amino acids daily because once any of the amino acids absent in our body the synthesis of protein will stop.
Nitrogen balance
Protein recommendations are based on nitrogen balance studies, which compare nitrogen excreted with nitrogen food.
This article helped me a lot with knowing about protein, but this article look more like a copy of a website, can you talk about more about your opinion about medical please, thank you.
ReplyDeleteFirst of all, my major is nutritional science so this is what I learned during class instead of a copy of a website. Second, this is a scientific article so I was trying to make the article as simple as possible for people to understand hence i did not write specific details. But in the next time I think I will try to add some personal views in it. By the way, thanks for your comment.
