Biochemistry: Molecules Of Life

Biological Molecules Inorganic compounds 1.Usually lack carbon 2.Generally split up in water or dissociate to produce ions 3. lesser in size than organic compounds 4.Usually held together by dome bonds 5.Inorganic substances common in cells are water, oxygen, carbon dioxide, inorganic salts. perfect compounds 1. crack carbon atoms 2.Most do non dissolve in water, those that testament do not release ions 3.Large complex compounds 4.Covalent bonds 5.Include carbohydrates, proteins, lipids Carbohydrates 1.Contain carbon, hydrogen, oxygen with 1:2:1 ratio of C:H:O 2.Three types: monosaccharides, disaccharides, and polysaccharides 3.Monosaccharides (simple sugars) a.Contain 3 to 6 carbons b.Examples: glucose (6C), ribose (5C) 4.Disaccharides a. constitute of 2 monosaccharides b.Examples: sucrose, lactose 5.Polysaccharides a.Composed of more monosaccharides b.Examples: glycogen, starch Proteins 1.Composed of amino acids 2. either amino acids contain an amine throng, a carboxyl mathematical group, and a variable radical (R). 3.Twenty dissimilar amino acids in proteins 4.Amino acids are joined together in chains by peptide bonds. 5.

Peptide bonds occur between the amine group on one amino acid and the carboxyl group on the adj thaumaturgistnt amino acid 6.Proteins differ in the following ship canal: a.Types of amino acids b.Arrangement or period of amino acids c. frame of amino acids d.Shapes of the molecules - linear, coiled, folded Lipids 1.Triglyceride molecule composed of glycerine and three greasy acids 2.Many diff erent roly-poly pudding acids occur in trig! lyceride forming many kinds of lipids. 3.Lipids may be saturated or unsaturated. a.Saturated - carbons in fatty acids are joined by a ace bond and to two H atoms b.Unsaturated - adjacent carbons in fatty acids are joined by recur covalent bonds and individually carbon lacks a hydrogen atom c.Polyunsaturated - contains many double bonds between carbons...If you want to get a just essay, revisal it on our website: OrderCustomPaper.com
