what are proteins used for in the body?

Answer 1

The structure of your body is a big connected web of protein.

(you are actually a KNITTED collagen shape, with specialised adaptations (eg. calcium & phosphorus in bones) woven into it for different purposes)

However, your body DOESN'T use proteins to build or repair these structures. The building blocks are AMINO ACIDS.

Your liver stores amino acids, and these are combined to make proteins, and each protein has a different structure, like putting together several Rubik's cubes to make a picture. There are thousands of different combinations, and only the exactly correct combination will make the right picture.

The proteins that are built and used in your body do all sorts of things that are part of other reactions; for example, most chemical reactions are CATALYSED (accelerated) by a protein.

Most of the structural proteins (eg collagen) are 'doing' nothing; they're just 'part of the furniture'. Even the interdigitating strands of Actin and Myosin in the muscles are inactive (it's an ATP/ADP 'ratchet' on the end that does the work).

The most important protein in your body is (arguably) haemoglobin. The shape of this molecule is precisely suitable for partially trapping iron, in a way that allows it to absorb and release oxygen. Too tightly trapped and it wouldn't absorb, too loose and it would oxidise too firmly.

The DNA coding system is a template or 'jig' that allows various proteins to be assembled by lining up a row of amino acids against the components in the DNA molecule, which is itself a protein.

Answer 2

haemoglobin and enzymes are made up of protein. Protein is extensively utilized to construct muscle groups. Nucleic acid aka as DNA or RNA have substantial applications in: -mitosis (enhance and restore of latest cells to swap ineffective ones) - meiosis (duplicate of intercourse cells) - protein synthesis (making proteins in the physique)

Answer 3

They are synthesized by your body and become your body. They are broken into amino acids then they are put back together according to your body and then are used for muscle, bone and other tissues growth and regeneration.

Answer 4

for all your body needs

Answer 5

...they are used for growth in the body like in muscles, height, etc.

Answer 6

it gives your body energy

Answer 7

to build tissue like muscle, skin, hair.

Answer 8

growth mainly

Answer 9

for health and energy

Answer 10

Everything :-)
