Lactose is a disaccharide composed of two subunits: glucose and galactose. These monosaccharides are linked together by a β-1,4-glycosidic bond. Lactose is primarily found in milk and dairy products and is broken down into its subunits by the enzyme lactase during digestion.
Hemoglobin is an example of a dimer. It is composed of two protein subunits that come together to form a functional molecule responsible for carrying oxygen in red blood cells.
The four kinds of subunits are: alpha subunits, beta subunits, gamma subunits, and delta subunits. These subunits play a crucial role in forming the structure and function of various macromolecules in biological systems, such as proteins or nucleic acids.
The subunits of Polysaccharides are monosaccharides
What is the fate of the newly formed subunits? What is the fate of the newly formed subunits?
Glucose and Galactose make up lactose Glucose and fructose make up sucrose Glucose and glucose make maltose
The subunits (or monomers) of carbohydrates are monosaccharides and disaccharides. The polymers (the products of these linked subunits) are starches and polysaccharides.
E. coli can metabolize glucose and grow well. It can also metabolize sucrose, but usually not as efficiently as glucose. However, E. coli typically cannot metabolize lactose unless it carries the necessary enzymes, such as beta-galactosidase from the lac operon. Without the ability to metabolize lactose, E. coli will not grow as well in a mixture of glucose, sucrose, and lactose compared to a mixture of only glucose and sucrose.
LACTOSE sugar
lactose
Cola is lactose free it has no lactose it has glucose in it !
1000's of proteins subunits can be made.
Carbohydrates are made up of glucose subunits . In complex carbohydrates long polymer chains of glucose subunits form the higher structure, they can be "nibbled" from either end by digestion enzymes. The breakdown into glucose is needed for metabolism. Sugar units are called saccharides in chemistry. Starch and cellulose are polysaccharides made from glucose. The difference in starch and cellulose is the manner in which the glucose units are bonded. Humans do not have the enzymes to digest cellulose. Simple sugars consits of small clusters of glucose, fructose and glactose subunits, amongst others that are all structually similar. Lactose found in milk is a carbohydrate sugar made from a glucose and galactose subunit.
