Key Concepts

Proteins

Proteins are large biomolecules composed of amino acid monomers. They play essential roles in nearly every cellular process, including catalysis, structural support, transport, and regulation.

Phospholipids

Phospholipids are a major class of lipids designed with a glycerol backbone, two fatty acid tails, and a phosphate group. They are fundamental to cell membrane structure, forming the lipid bilayer that separates and protects the internal environment of cells.

Fats (Lipids)

Fats, often referred to as triglycerides, are lipids composed of a glycerol backbone esterified with three fatty acids. They function mainly as energy storage molecules and are critical for insulation and cellular energy reserves.

Nucleic Acids

Nucleic acids, such as DNA and RNA, are polymers built from nucleotide monomers. They store and transmit genetic information, guiding cell function and heredity.

Polysaccharides

Polysaccharides are complex carbohydrates made up of many monosaccharide units linked together. They serve various roles including providing structural integrity in cell walls and acting as energy reserves.

Nucleotides

Nucleotides are the building blocks of nucleic acids. Each nucleotide contains a sugar, a phosphate group, and a nitrogenous base, and they are also involved in energy transfer and cellular signaling.

Waxes

Waxes are lipids that are typically formed by the esterification of long-chain fatty acids with long-chain alcohols. They function as protective, water-resistant coatings in plants and animals.

Disaccharides

Disaccharides are a type of carbohydrate formed by the linkage of two monosaccharide units via a glycosidic bond. They serve as a readily accessible source of energy in many organisms.

Transcript

00:03 Hi there, let's talk about some common biological molecules and their composition in this problem.

00:10 So we have a matching problem here, and the first term we are trying to match up is protein.

00:20 And proteins are macromolecules, and they are composed by linking several amino acids together.

00:29 So proteins result from bonding or linking many, many amino acids together.

00:36 Connected by peptide bonds.

00:38 So we get a polypeptide, which is also known as a protein.

00:42 So this would match up with letter f.

00:46 Our next one is phospholipids.

00:55 One of the places we are going to see phospholipids the most are in cell membranes.

01:02 And phospholipids are going to be made up of not only a phosphate group, but also glycerol and fatty acids.

01:10 So this is going to be letter a.

01:14 Our next term are fats.

01:20 If we think about fats, fats are basically molecules that are composed of an alcohol known as glycerol, as well as fatty acids.

01:30 So this is going to be letter b.

01:34 Next we have nucleic acids.

01:40 When you think of nucleic acid, you probably correctly think of either dna or rna.

01:47 In this case, we know that nucleic acids are composed of those nucleotide monomers bonded together over and over to make the dna or the rna macromolecule.

02:01 So that would be letter c.

02:06 Next one we have is cellulose.

02:13 Cellulose is found in plants, and cellulose is the result of linking many, many sugar molecules together, specifically.

02:24 Glucose monomers...
