Which elements are found in carbohydrates and what is their general formula?
Carbohydrates are made up of carbon,hydrogen and oxygen.
Their general formula is Cx(H20)y.
Monosaccharides and disaccharides are sweet, soluble in water and generally function as energy supplies. Monosaccharides also perform structural roles e.g ribose and deoxyribose are pentose sugars with a structural role in nucleic acids.
Globular proteins have a roughly spherical shape and have a physiological function e.g enzymes
Fibrous proteins are usually long,coiled strands of flat sheets and have a structural function e.g collagen.
Polysaccharides are carbohydrates which consist of large numbers of monosaccharides joined together by glycosidic bonds.
The following are all proteins:
Haemoglobin transports oxygen in red blood cells.
Antibodies protect the body from infection.
Enzymes catalyse metabolic reactions.
Hormones are responsible for chemical co-ordination in living organisms.
