The glycemic index is an indicator of the speed of resorption and conversion to blood glucose levels from ingested carbohydrates, measured as the area under the curve of blood glucose levels after consumption in comparison to glucose (glucose is defined as 100).

Electrolyte drinks containing six-eight per cent carbohydrate are known as isotonic – they contain the same concentration of dissolved particles (salts and sugars) as body fluids, which promotes hydration. If you have a fruit juice craving that won’t fade, be sure you pick up a juice that’s 100 percent pure and contains no added sugars.

Another enzyme, peroxidase, catalyzes a chromogenic reaction (Trinder reaction) [125] of phenol with 4-aminoantipyrine to a purple dye. a b Boerio-Goates, Juliana (1991), "Heat-capacity measurements and thermodynamic functions of crystalline α-D-glucose at temperatures from 10K to 340K", J.

They are also sometimes fortified with important nutrients like calcium and vitamin D, both of which play a key role in bone health.

Best energy drinks for cycling: fuelling and hydration explained

Failure to replace electrolytes, or dilution through excessive intake of plain water can result in hyponatremia (low levels of sodium) leading to muscle cramps, lethargy, nausea, headaches and in severe cases, death.

Consuming carbohydrate during endurance exercise delays fatigue and boosts performance, but the amount that can actually be delivered to the working muscles is limited by the rate at which it can be absorbed from your digestive tract. In principle, cellulose could be hydrolyzed to glucose, but this process is not yet commercially practical. These include lactose, the predominant sugar in milk, which is a glucose-galactose disaccharide, and sucrose, another disaccharide which is composed of glucose and fructose.
