Different biomolecules can be classified as aldehyde, ketones and aromatic compounds as chemical forms. P-N bonds. CBSE quick revision note for class 11 Mathematics, Physics, Chemistry, Biology and other subject are very helpful to revise the whole syllabus during exam days. In class 11th biomolecules notes, you will know about the common … e.g., Protein from amino acids. Nucleoside : Nitrogenous base + Sugar e.g., Adenosine, guanosine. Lipids are not strictly macromolecules as their molecular weights do not exceed Biomolecules Notes Class 12 Chemistry Chapter 14 Edubuzz Notes by edubuzznotes.com. chains are antiparallel, and held together by hydrogen bonds (two between A and The major difference between inorganic and organic catalyst is inorganic catalyst works effectively at high temperature and pressure but enzyme get damaged at high temperature. It exists only in 1% but constitutes 80% of the dry weight of plants. There are two kinds of amino acids-. tosamine. Activity 2 α α acid and the amino (-NH protein in hair, Biomolecules are divided into two types- inorganic and organic. Form coordination bond with e.g., Human haemoglobin The Notes covers all important points which provide the students a simple way to study or revise the chapter. Micromolecules : Molecules which have molecular weights less than one thou- Ligases – catalyses the linking together of two compounds. molecule has 4 peptide chains - 2a and 2b subunits. Ligases : Catalyse linking together of 2 compounds. Concentration of Substrate– increase in substrate concentration increases the rate of reaction due to occupation of more active sites by substrate. Photosynthesis and protein synthesis are example of anabolic pathway. carbons). E.g., NAD, NADP. • Is a heteropolymer. Biomolecules Class 11 CBSE Revision Notes. The nucleic acids that behave like enzymes are called ribozymes. A nucleic acid has three chemically distinct components- heterocyclic compound ( nitrogenous base), polysaccharides ( ribose/ deoxy-ribose sugar) and phosphate or phosphoric acid. Enzymes are commonly proteinaceous substances which are capable of catalysing chemical reactions of biological origin without themselves undergoing any change. Important Questions for Class 11 Biology Chapter 9 Biomolecules Though there is diversity in living entities, they share similarities in the chemical composition and metabolic reactions. (a) Temperature : Show highest activity at optimum temperature. It can hold the I. Cellulose molecules contain glucose molecules joined together by 1-4 β linkage. 6. Carbohydrates are products of plants and are a part of an extremely large group of naturally occurring organic compounds. The general formula for carbohydrates is Cz(H2O)y. Carbohydrates are generally hydrates of carbon, which is where the name was derived. apoenzyme. CBSE Syllabus Class 12 Maths Physics Chemistry ...
