Lipids are organic molecules that are insoluble in water but soluble in non-polar solvents. They provide structure to cell membranes, store energy, and function as signaling molecules. Lipids include fats, oils, waxes, phospholipids, glycolipids, steroids, terpenes, and carotenoids. Fats and oils are triglycerides made of glycerol bonded to three fatty acids, and are solid or liquid depending on temperature. Phospholipids contain fatty acids, glycerol, and a phosphate group, giving them a polar structure. Steroids do not contain fatty acids and are nonsaponifiable.

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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
2. • Definition : Lipids are organic molecule of biological origin
that are insoluble in water and soluble in non-polar
solvents.
• The chemical composition of these molecules includes
hydrogen, carbon, and oxygen.
• They provide high energy and perform three important
biological functions in the body: to provide structure to cell
membranes, to store energy, and to function as signalling
molecules.
• They include fats and oils – mostly triglycerides
– Fat: solid at room temperature
– Oil: liquid at room temperature
4. • Simple lipids are esters of fatty acid linked with various
alcohols.
• Fats and oils (triglycerides)
• These esters of fatty acid have glycerol, a trihydroxy alcohol.
• Triglycerides are abundant and constitute about 98 percent of
all dietary lipids.
• Waxes
• Waxes are long-chain saturated and unsaturated fatty acid
esters with monohydroxy alcohols, which have high molecular
weight.
• Waxes are produced naturally by skin glands as a protection,
to keep it lubricated and water-proof.
5.
6. • Heterolipids are fatty acid esters with alcohol and additional groups.
• Phospholipids (phosphatids)
• Phospholipids contain fatty acids, glycerol, nitrogen bases, phosphoric acid,
and other substituents. As their name implies, phospholipids contain
phosphorus in the form of phosphoric acid groups. Their molecular
structure is polar, consisting of one hydrophilic head group and two
hydrophobic tails.
• Glycolipids (cerebrosides)
• Glycolipids are fatty acids with carbohydrates and nitrogen but without
phosphoric acid. Glycolipids also include some compounds like sulfolipids,
gangliosides, and sulfatids which are structurally-related.
7.
8. • These substances are derived by hydrolysis from compound and
simple lipids. These fatty acids include carotenoids, steroids, and
terpenes.
• Steroids
• The steroids are the most studied types of fat. They contain no fatty
acids and unlike fats, are nonsaponifiable (cannot be hydrolyzed to
yield soap).
• Cholesterol
• Cholesterol is a well-studied lipid, because of its strong correlation
with the incidence cardiovascular disease. It is an important
component of cell membranes and plasma lipoproteins, and is an
important precursor of many biologically important substances like
bile acids and steroid hormones.
9.
10. • Terpenes
They are large group of volatile unsaturated
hydrocarbons found in the essential oils of plants,
especially conifers and citrus trees.
• Carotenoids
They are a class of mainly yellow, orange, or red fat-
soluble pigments, including carotene, which give
colour to plant parts such as ripe tomatoes and
autumn leaves.
