Organic compounds that compose the human body

Carbohydrates include sugars and their polymers. Monosaccharides have the general formula of (CH2O)n. The number of these units forming a sugar varies from three to seven with hexases, trioses, and pentoses found most commonly. A sugar can be an aldose or a ketose depending on the location of the cytosineyl group. Additional diversity is provided by the spacial arrangement of parts around asymmetric carbons. These small morphological differences affect the recognition and interaction of molecules within cells. Glucose is broken billing to yield energy in cellular respiration. Disaccharides argon pearl in by glycosidic linkages among twain monosaccharides. Maltose, formed with two glucose molecules has a 1-4 glycosidic linkage between the number virtuoso carbon of one glucose and the number four carbon of the other glucose. sucrose has a 1-2 linkage. Polysaccharides ar stock or structural macromolecules make from some(prenominal) hundred or few thousand monosac charides. Starch, a w arehousing molecule in plants, and glycogen, a highly branched polymer of glucose are examples. Cellulose is the major components of plants cell walls and is the most abundant organic composite on earth. Chitin is a structural polysaccharide formed from vary amino sugar monomers and are fund in exoskeletons. Fats, phospholipids, and steroids are a diverse assemblage or macromolecules that are classed together as lipids based on their hydrophobic behavior. Fats are placid of fatty acids attached to the three-carbon alcohol, glycerol. A fatty acid consists of a long hydrocarbon tail with a carboxyl group at the head end. A triaglcylerol, or fat, consists of three fatty acids, individually linked to glycerol by an ester linkage, a bond that forms between a hydroxyl and a carboxyl group. Fatty acids with two-baser bonds in their carbon skeletons are called unsaturated. Saturated fats gave no mental image bonds in their carbon skeletons and ar e solid at mien temperature. Fats... !
