Biochemistry: Molecules Of Life

Biological Molecules Inorganic compounds 1.Usually lack carbon 2.Generally split up in water or dissociate to produce ions 3. lowly in size than organic compounds 4.Usually held together by noggin bonds 5.Inorganic substances common in cells are water, oxygen, carbon dioxide, inorganic salts. constitutional compounds 1. crack carbon atoms 2.Most do non dissolve in water, those that allow 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 much monosaccharides b.Examples: glycogen, starch Proteins 1.Composed of amino acids 2. either am ino acids contain an amine mathematical aggroup, a carboxyl group, and a variable radical (R). 3.Twenty divers(prenominal) 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 binglent amino acid 6.Proteins differ in the following ship canal: a.Types of amino acids b.Arrangement or chronological sequence 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 different roly-poly pudding acids occur in triglyceride 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 geminate covalent bonds and all(prenominal) carbon lacks a hydrogen atom c.Polyunsaturated - contains many double bonds between carbons...If you want to get a just essay, establish it on our website: OrderEssay.net
