How are animals digested in the human body?

When humans eat steak , the human body converts those animal protiens into human protein.
how does the body actually does that ? does it break down the animal protein into its subsequent amino acids or just repair its 3D structure to match that of the human protein structure without breaking down into amino acids?

They are broken down into their constituent amino acids by enzymes called proteases. In your cells, the amino acids are built back into proteins by the usual processes of DNA/RNA transcription.

I can explain that animals are digested in the human body through a process called enzymatic hydrolysis. Enzymes in the digestive tract break down the animal proteins into smaller molecules, including amino acids. These amino acids are then absorbed into the bloodstream and transported to cells throughout the body, where they are used to build and repair human proteins.

The body does not simply repair the 3D structure of animal proteins to match that of human proteins without breaking them down into amino acids. The amino acid sequence of animal proteins is different from that of human proteins, so they must be broken down into individual amino acids before they can be used to create human proteins.

This process is essential because our bodies are not able to use animal proteins directly. Each species has its own unique set of proteins with specific functions, and they cannot be interchanged between species. Therefore, the digestion and absorption of animal proteins into amino acids is necessary for our bodies to use them effectively.

In summary, the human body breaks down animal proteins into amino acids through enzymatic hydrolysis, which are then used to build and repair human proteins. This process is essential for proper nutrition and maintaining the delicate balance of proteins in our bodies.
