Lipids are insoluble in water but soluble in nonpolar solvents. They serve important structural and energy storage functions in biological systems. Lipids can be classified as fatty acids, waxes, triglycerides, phosphoglycerides, sphingolipids, glycolipids, and steroids. Fatty acids are the building blocks of more complex lipids and some must be obtained through diet. Triglycerides are the main form of lipid energy storage. Phosphoglycerides are important components of cell membranes. Cholesterol is an essential steroid lipid that is a precursor for other steroids and bile acids.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
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.
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”.
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.
2. WHAT ARE LIPIDS?
• Lipids are insoluble in water but soluble in non polar
solvents.
• Lipids can be dispersed uniformly in water in the form of
minute droplets.
• Lipids are the actual or potential esters of higher fatty
acids.
• Lipids are highly energetic.
3. FUNCTIONS
• Structural components of biological membranes.
• Energy reserves mainly in the form of triacyl-glycerols.
• Serve as vitamins and hormones or their precursors.
• Thermal insulators.
• Wax coating that protects plants.
5. FATTY ACIDS
• Fatty acids are long chain aliphatic carboxylic acids.
• Fatty acids in natural fats contain an even number of
carbon atoms.
• The carbon chains may be saturated (all single bonds) or
unsaturated (containing double bonds)
• The double bonds are usually in cis configurations.
6. ESSENTIAL FATTY ACIDS
• Linoleic acid, linolenic acid and arachidonic acid, these
cannot be synthesized in the body and must be obtained
from the diet. These are essential fatty acids.
7. WAXES
• Waxes are esters of fatty acids and long chain or higher
monohydroxy alcohols.
Examples:-
• LANOLIN
• SPERMACETI
• WAX-D
• BEEWAX
8. TRIGLYCERIDES
• These are commonly called simple fats or oils.
• These are particularly present in the adipose tissue of the
body.
• These are the esters of fatty acids and glycerol.
11. SOAPS
Each soap molecule has a long hydrocarbon chain,
sometimes called its 'tail', with a carboxylate 'head'. In
water, the sodium or potassium ions float free, leaving a
negatively-charged head.
13. PHOSPHOGLYCERIDES
• These are also called phospholipids.
• These in addition to fatty acid and glycerol, also contain a
phosphate.
• These are the main constituents of the cell membrane
lipids and are also found in brain and cardiac tissues.
14. LECITHINS:-These phospholipids are obtained when a
nitrogenous base choline gets attached to the -OH
group of phosphate of phosphatidic acid.
CEPHALINS:-Phosphoglycerides that contains the amino
alcohols ethanolamine or serine are called cephalins.
15. SPHINGOLIPIDS
• Sphingolipids are complex lipids that contain sphingosine
instead of glycerol.
• One important type of sphingolipids are the
sphingomyelins.
16. GLYCOLIPIDS
• Glycolipids are sphingolipids that contain carbohydrates
(usually monosaccharide).
• They are also referred to as cerebrosides because of their
abundance in brain tissue.
• These are present mainly in the outer part of the cell
membranes.
17. STEROIDS
• Steroids are classified as lipids because they are soluble in
nonpolar solvents, but they are nonsaponifiable.
• The basic steroid structure contains four fused rings.
CHOLESTEROL:-
• It is an essential component of cell membranes, and is a
precursor for other steroids.
• There is apparently a correlation between high levels of
cholesterol in the blood and atherosclerosis.
BILE ACIDS:-
• Bile is a yellowish brown or green fluid produced in the liver.
• Bile salts act like soaps and other emulsifiers.
18. PROSTAGLANDINS
• Prostaglandins are cyclic compounds synthesized from
arachidonic acid.
• Like hormones, they are involved in a host of body
processes, including reproduction, blood clotting,
inflammation, and fever.
