Relating to or denoting the compound creatine phosphate, which serves as an important energy source in muscle cells.
Compound adjective combining 'creatine' (from Greek 'kreas,' meat) with 'phosphoric' (relating to phosphorus). This technical term emerged in early 20th-century biochemistry as researchers discovered the role of phosphate compounds in muscle energy.
Creatine phosphate is your muscles' emergency energy fund—when you sprint suddenly, your body uses stored creatine phosphate before tapping into longer-term energy sources, which is why it's the first seconds of exertion.
