Carbohydrates are polyhydroxy aldehydes, ketones, or compounds derived from their hydrolysis.
Carbohydrates are also known as sugars.
Carbohydrates have the general formula C(H2O)n, where n is the number of carbon atoms.
Carbohydrates are mainly composed of carbon, hydrogen, and oxygen.
The term “sugar” is applied to carbohydrates that are soluble in water and sweet to taste.
Any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.
Chemically, carbohydrates are defined as “optically active polyhydroxy aldehydes or ketones or the compounds which produce units of such type on hydrolysis”.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Fructose
1. WELCOME TO THE CLASS
THIS POWERPOINT IS ABOUT
FRUCTOSE
LEARN ABOUT FRUCTOSE
Done by Dr.T.Venugopal
2. Fructose
Fructose, or fruit sugar, is a simple ketonic monosaccharide found in
many plants. Chemical formula is C6H12O6.
Fructose is absorbed directly into blood during digestion. Fructose was
discovered by French chemist Augustin in 1847.
The name "fructose" was coined in 1857 by the English chemist William
Allen Miller.
Pure, dry fructose is a sweet, white, odorless, crystalline solid, and is the
most water-soluble of all the sugars.
Fructose is found in honey, vine fruits, flowers, berries, and most root
vegetables
3. • Fructose has a cyclic structure.
• Due to the presence of the keto group, it results in the formation of
intramolecular hemiacetal.
• In this arrangement, C5-OH combines with the ketonic group present
in the second position.
• This results in the formation of chiral carbon and two arrangements
of CH2OH and OH group.
• Hence D-fructose exhibits stereoisomerism in which α-D-
fructopyranose and β-D-fructopyranose are the isomers.
Structure of Fructose
4. Sucrose
• Sucrose is common table sugar.
• It is a disaccharide, a molecule composed of two monosaccharides,
des, glucose and fructose.
• Sucrose is produced naturally in plants, from which table sugar is refined. It
has the formula C12H22O11.
• Sucrose is most abundant among all the naturally occurring sugars. It is
used as sweetening agent in food industry.
• It is sweeter than some common sugars like glucose, lactose and maltose.
• It is a colourless, crystalline and sweet substance soluble in water. Sucrase
is the enzyme that can hydrolyze sucrose in the body.
5. Structure of Sucrose
• If sucrose goes through acid catalysed hydrolysis it will give one mole of D-
Glucose and one mole of D-Fructose.
• The chemical structure of sucrose comprises of α form of glucose and β
form of fructose
• The glycosidic linkage is α linkage because the molecule formation is in α
orientation
• Sucrose is a non-reducing sugar. As you can see from the structure it is
combined (linked) at the hemiacetal oxygen and does not have a free
hemiacetal hydroxide
• Since sucrose has no free hemiacetal hydroxide it does not show
mutarotation (α to β conversion). Sucrose also does not form osazones for
the same reason.
6. Starch
• Starch is a glucan, meaning it only consists of glucose molecules all
linked together by glycosidic bonds.
• The general molecular formula for starch is ( C6H10O5 )n.
• The ‘n’ denotes the number of molecules linked together. Starch
occurs in all plants, particularly in their seeds.
• The main sources are wheat, maize, rice, potatoes and barley. Starch is
a white amorphous powder, insoluble in cold water. It gives a blue
colour with iodine solution.
• The blue colour disappears on heating and reappears on cooling. On
hydrolysis with dilute acids or enzyme, starch breaks down into
molecules of variable complexity and finally into D-Glucose.
7. Starch
• Structure of starch:
• Starch consists of two polysaccharide components. They are amylose (20% -
80%) and amylopectin (80% - 90%).
• Amylose is water soluble, long unbranched (linear) chain with 200-1000 D-
glucose units.
• In amylose the D-glucose units are joined together by a 1-4 glycosidic
linkage i.e. C-1 of one glucose unit and C-4 of the other glucose unit are
joined together.
• Amylopectin is water insoluble, branched chain with 20-30 glucose units per
branch.
• In amylopectin the units are held with two types of glycosidic bonds, a 1-6
glycosidic bonds at branching points and a 1-4 glycosidic bonds in the linear
chain.
8. Cellulose
• Cellulose is a tough, water insoluble and fibrous
polysaccharide organic compound with the formula (C6H10O5)n,
a polysaccharide consisting of a linear chain of several hundred to
many thousands of β(1→4) linked D-glucose units.
• Cellulose is an important structural component of the primary cell
wall of green plants.
9. Structure of cellulose
• The D-glucose units in cellulose are connected in (1→4) fashion.
• The linkage is β-glucosidic linkage.
• The structure is not helical since the beta linkage confines the
polysaccharide to a straight-chain form.
• When subjected to acetolysis i.e. simultaneous acetylation and
hydrolysis, cellulose forms cellobiose octo-acetate, which confirms
the presence of cellobiose units in cellulose
