Summary of Carbohydrates: Monosaccharides‚ Disaccharides‚ Polysaccharides Carbohydrates are molecules that are synthesized from carbon‚ oxygen‚ and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms‚ while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch

Disaccharides Sucrose A crystalline disaccharide of fructose and glucose‚ C12H22O11‚ found in many plants but extracted as ordinary sugar mainly from sugarcane and sugar beets‚ widely used as a sweetener or preservative and in the manufacture of plastics and soaps‚ also called saccharose. Sucrose is one of the main products of photosynthesis and the most common transport sugar in plants. It is also a no reducing disaccharide‚ and is synthesized in the cytosol via the phosphorylated intermediate

monosaccharide‚ which is a simple sugar. The monomer for the lipid is fatty acid in milk its triglyceride. I did not understand the nucleic acid formation in milk. 3. The molecular formula for the milk disaccharide is formed when two monosaccharides are bonded by dehydration synthesis.. A disaccharide must be digested into a simple sugar. I am now interested in knowing how this type of synthesis works. 4. The calcium in the milk helps to strengthen the bones. The amino acids provide a good source

Aim: To find out which samples consists of starch/ proteins/ reducing sugar/disaccharide out of 4 given samples A‚ B‚ C and D. Research Question: Out of the four given samples which sample consists of protein/ starch/reducing sugar/ disaccharide? What color changes will help to identify the contents of each sample when treated with iodine‚ biuret agent and benedicts solution? Theory and background information: What is a protein?1 Proteins are macromolecules‚ consisting of one or more chains

celluloses are structural components of the walls that surround plant cells. * The carbohydrates (saccharides/sugars) are divided into four chemical groups: monosaccharide‚ disaccharides‚ oligosaccharides and polysaccharides. * Monosaccharides include Glucose‚ Fructose‚ and Galactose etc. * Disaccharides include Sucrose‚ Maltose‚ and Lactose etc. * Polysaccharides include Starch‚ Glycogen‚ Cellulose and Chitin. * Aldehydes (–CHO) and ketones (= CO) are active groups or

and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are formed from the condensation reaction between two monosaccharaides and are linked by glycoside bond. All monosaccharaides and some disaccharides such as maltose and lactose are reducing sugars due to the presence of aldehyde or keto

role of carbohydrates is the production of energy. Carbohydrates are groups of sugars that contain carbon‚ oxygen‚ and hydrogen in a 1:2:1 ratio. Three main units of carbohydrates are monosaccharides‚ disaccharides‚ and polysaccharides. Monosaccharides are a single chain of CH2O while disaccharides are two units bonded together through dehydration reaction but they are both considered sugars. Polysaccharides on the other hand are a combination of three or more units of monosaccharides put together

bloodstream during digestion. Sorbose - it is a ketose belonging to the group of sugars known as monosaccharides. It has a sweetness that is equivalent to sucrose. The commercial production of vitamin C often begins with sorbose. Maltose – it is a disaccharide formed from two units of glucose joined with an α bond‚ formed from a condensation reaction. The isomer isomaltose has two glucose molecules linked through an α bond. • Independent variables – the sugar type we change. • Dependent variables –
