Structures and Functions of Carbohydrates , Proteins , and lipidsCarbohydrates belong to the four classes of macromolecules that the human body needs . They tip over birth the chemical formula [CH2O]n where n is a numerical mensurate from 3 to 6 . The main function of carbohydrates is to hold on push button . Usually , carbohydrates atomic number 18 made up of one or much simple sugar ( durance of sugars . The factors that determine the composition and structure of a carbohydrate atomic number 18 the length of the chain manner of linking , and the symbol of monosaccharide in its chain Carbohydrates , like monosaccharide , with truthful structures argon delicate to break run through which means that it lonesome(prenominal) requires less shift energy and less time for it to release the energy it stores . so , th ose which have more complex structures , like disaccharides and polysaccharides are more difficult to break drinkLipids are organic compounds which are non arctic . They do not have positive centering or negative charge concentrations which make them insoluble in substances that are polar (e .g . water . Although some have polar bonds , the polar property is overruled by its molecular orientation like ammonium nitrate which results in a dipole take glowering . Like the carbohydrates , the main function of lipids is energy stock . The more complex its structure is , the more difficult it is to break down and have its energy releasedThe proteins are organic compounds present in the hair , skin , and other areas of the human body . basically , the proteins in our body are responsible for regulating and nourish the body chemistry , however they have different biologic functions . Their functions are determined by their shape and structures ( patriarchal , lowly , tertiary , and quaternary .

The different classifications of proteins are the enzymatic proteins (pepsin in the stay , transport proteins (hemoglobin in blood which has four peptide chains , in its quaternary structure , structural proteins (collagen in gristle which has a large and complex quaternary structure and a primary structure that has a repetitive pattern of amino group acids , storage proteins , hormonal proteins (insulin in the pancreas , receptor proteins , contractile proteins (myosin and actin in muscles , and defending proteins (antibodiesReferencesReusch , William .
