HUMAN NUTRITION

Detailed explanation-1: -Muscles are made up of individual fibers constructed of proteins, and these proteins are made up of amino acids connected to one another in long strings of almost infinite variety.

Detailed explanation-2: -To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.

Detailed explanation-3: -Protein is the main component of muscles, bones, organs, skin, and nails. Excluding water, muscles are composed of about 80% protein, making this nutrient especially important for athletes.

Detailed explanation-4: -Free amino acid deposition in muscle often accounts for as much as 80% of the total amount in the whole body. In contrast, plasma contains a very small proportion of the total amino acid pool, ranging from 0.2 to 6% for individual amino acids.
