Correct Answer: ken found that there are 20 different types of amino acids.
ken, driven by his curiosity about nutrition, embarked on a journey to understand more about amino acids, which are the building blocks of proteins. proteins play a crucial role in various biological processes, including the repair of body tissues. in his research, ken explored the different types of amino acids that exist and their roles in the human body.
during his investigation, ken discovered that proteins are made up of amino acids, which are organic compounds composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. these compounds link together in chains to form proteins. the sequence and type of amino acids in these chains determine the properties and functions of the proteins.
ken found varying information regarding the number of amino acids. some sources mentioned 15, 25, or even 30 different types of amino acids. however, the most consistent and widely accepted number he encountered in scientific literature was 20. these are known as the standard amino acids, which are encoded directly by the genetic code and are essential for life.
out of these 20 amino acids, nine are considered essential amino acids because the human body cannot synthesize them. they must be obtained through diet. the remaining 11 are nonessential amino acids, which the body can produce on its own.
in conclusion, ken confirmed that there are 20 standard amino acids essential for various biological functions, particularly in protein synthesis. this discovery not only satisfied his curiosity but also expanded his knowledge on the fundamental components of nutrition.
