Document Summary
Proteins: proteins are made up of amino acids, amino acids all have a similar structure, with different side chains, proteins contain nitrogen in addition to carbon, hydrogen and oxygen. Carbohydrates: carbohydrates consists of carbon, hydrogen and oxygen molecules, these are simple sugars such as sucrose and lactose and starch, glucose, fructose and galactose are monosaccharides which make up the simple sugars. Lipids: lipids, or fats are composed of fatty acids and glycerol, they contain less oxygen than carbs or protei(cid:374)s, the(cid:455) are (cid:373)ore (cid:862)reduced(cid:863) so (cid:455)ield (cid:373)ore e(cid:374)erg(cid:455) whe(cid:374) (cid:862)o(cid:454)idized(cid:863) Structure: proteins provide structure in the body, as well as allowing reactions to proceed (catalysis), protecting us, transporting nutrients, controlling body processes and providing energy. Information: dna supplies the information to create protein molecules which govern biochemical processes. Biochemistry: atp is produced though the oxidation of dietary fuels, the high energy phosphate bond of atp is broken to supply energy, adp is regenerated to atp and the cycle begins again.
