Amino acids. Building blocks of proteins.
The primary function of protein is to build and repair body tissues and structures.
Protein is involved in the growth and repair of every cell in the human body.
20 amino acids are needed to make protein.
Amino Acids link by peptide bonds and form proteins.
Different sources of protein supply varying combinations and quantities of amino acids.
Three Kinds of Amino Acids
Studying for the NASM CPT Exam? Be sure you can recognize the essential amino acids. Know there are 8 of them. Know there are 20 amino acids that make up protein.
Essential Amino Acids (8): Amino acids that cannot be manufactured by the human body and must be found in your food supply.
Nonessential Amino Acids:
Amino acids the body can manufacture from dietary nitrogen and fragments of carbohydrate and fat: alanine, asparagine, aspartic acid, cysteine, glutamine, glutamic Acid, glycine, proline, serine and tyrosine
Semiessential Amino Acids (2): There are two kinds of amino acids that, due to the rate at which the body synthesizes them, can’t quite be called nonessential. While the body does in fact make them, arginine and histidine cannot be manufactured by the body at a rate that will support growth, especially in children.
Some sources say…
…there are 10 essential amino acids. Both numbers make sense now, right?
(Just be sure you know 8 for the NASM CPT exam!).
