Key Concepts

Steroids

Steroids are characterized by a core structure of four fused carbon rings. They play critical roles as hormones and signaling molecules, and they are also involved in maintaining membrane integrity and fluidity.

Phospholipids

Phospholipids have a glycerol backbone, two fatty acids, and a phosphate group, rendering them amphipathic. This duality is essential for forming the bilayer structure of cell membranes, contributing to membrane fluidity and function.

Triglycerides (Fats)

Triglycerides consist of glycerol esterified with three fatty acids. They are primarily used for energy storage in organisms and constitute the main fats found in foods.

Waxes

Waxes are composed of long-chain fatty acids esterified with long-chain alcohols. Their hydrophobic nature makes them ideal for protective coatings and water-repellent functions in nature.

00:02 Hi, today my students, i discuss with you, libets and libid categories.

00:13 So today, limits.

00:23 Before i start, i want to define what are the limits.

00:30 Libits are class of macromolec, class of macromolecules, that are non -poolar, that are non -polar and hydrophobic in nature, non -polar, and hydrophobic in nature.

01:42 So this is libids, this is libid.

01:45 This is libid.

01:47 Libid.

01:47 Libid, our limits are class of macromolecules that are non -polar, non -polar, and hydrophobic in nature.

02:00 Okay, okay.

02:03 What are the major types of lipids? measure, major types.

02:20 Major types of limits include, number one, fat and oil, fat and oil.

02:32 Okay that's a diet two waxes three phospho limits last one is steroid fosphoid fosphoid limits for steroids okay okay fats are stored form of energy are stored form of energy and also known as triagiclycerals or triglycerides.

03:50 Okay.

03:52 Code tri -glycerides.

03:59 Try -traclycerides.

04:18 Okay.

04:24 As you know, fats, fats are made up of fatty acid.

04:33 And either glycerol or spengicin.

04:36 Yep.

04:36 So fats is made up of fatty acids, fatty acids and either glycerol or grisrol or what? or sphinxen, yes, sphingsten.

05:16 Okay, okay.

05:20 So fats is composed of fatty acid and glycerol or sphinx or sphinx.

05:27 Okay, fatty acid, as you know, fatty acid may be saturated or unsaturated, may be saturated and unsaturated.

06:01 Unsaturated.
