2. The endorphins are a group of naturally occurring neurotransmitters that act in a manner like morphine to control pain. Research has shown that the biologically active parts of the endorphin molecules are simple pentapeptides called enkephalins. Draw the structure of the methionine enkephalin with the sequence Tyr-Gly-Gly-Phe-Met. Identify the N- terminal and C-terminal amino acids.
Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.
2. The endorphins are a group of naturally occurring neurotransmitters that act in a manner
like morphine to control pain. Research has shown that the biologically active parts of the
endorphin molecules are simple pentapeptides called enkephalins. Draw the structure of
the methionine enkephalin with the sequence Tyr-Gly-Gly-Phe-Met. Identify the N-
terminal and C-terminal amino acids.
3. Bradykinin is a nonapeptide that stimulates smooth muscle contraction, dilates blood
vessels, causes pain, and is a component of bee venom. Give the IUPAC name of the
nonapeptide.
4. Some researchers feel that the “high” experienced by runners may be due to the brain’s
synthesis of peptides. Explain why this theory might be a reasonable explanation
