What elements make up proteins? - Socratic
Jan 22, 2014 · Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen and Nitrogen. Proteins are crated by linking together amino acids into protein links called polypeptide chains. There are twenty amino acids of which 12 can be synthesized by the human body and 8 must be ingested in the foods we eat. These 8 are referred to as the essential amino acids. …

Mar 2, 2016 · A component of protein called serine has an approximate molar mass of 100 g/mole. If the percent composition is as follows, what is the empirical and molecular formula of serine? The percent composition is: C=34.95% H = 6.844% O=46.56% and N=13.59%.
What is the chemical composition of proteins? - Socratic
Oct 30, 2015 · There are 20 different amino acids which make up proteins. Each amino acid consists of a central carbon. The central carbon is bonded to an amine group (#NH_2#), a carboxyl group (COOH), a hydrogen atom and an R group.
Compare the composition of blood, tissue fluid, and lymph?
Jan 14, 2018 · However, it contain proteins secreted by body cells. It contains less glucose, proteins, O_2 & more CO_2 as compared to blood. When tissue fluid gets enclosed in lymph capillaries then it is called lymph. So it's composition is not that different from tissue fluid. It just contain a little bit lower amount of proteins, glucose and O_2.
How do proteins differ from carbohydrates and lipids? - Socratic
Jun 13, 2015 · Proteins are large molecules that consist of long chains of amino acids joined together by peptide ("CONH") bonds. Proteins The structure of a small protein is Proteins have polar C=O and N-H groups, so they are able to form hydrogen bonds with other molecules and with each other. Carbohydrates Carbohydrates have many polar "OH" groups. A typical …
What elements make up lipids? + Example - Socratic
Jun 10, 2014 · See below. > All lipids contain carbon, hydrogen, and oxygen. Some of them also contain nitrogen and phosphorus. The four main classes of lipids are fats, waxes, sterols, and phospholipids. Fats Fats are triglycerides. They are triesters formed by the reaction of glycerol and any of several fatty acids. Fats may be either solid or liquid at room temperature, …

Jan 10, 2016 · The four macromolecules are nucleic acids, carbohydrates, proteins, and lipids. Structure: 1. Nucleic acids: Contain N in rings, nucleotides made of sugar, phosphate and nitrogenous base Carbohydrates: Made of C,H, and O; –OH's on all carbons except one Lipid: Made of C,H, and O; lots of C-H bonds; may have some C=C bonds (unsaturated) Protein: …
What is the difference betweet molecular mass (Mr) and molar
Aug 15, 2016 · See explanation. Molecular mass is a term used to denote the mass of a single molecule and is measured in unified atomic mass units, "u", much like atomic mass, which denotes the mass of a single atom.
Percent Composition - Chemistry - Socratic
Percent composition in chemistry typically refers to the percent each element is of the compound's total mass. The basic equation = mass of element / mass of compound X 100%. For instance, if you had a 80.0 g sample of a compound that was 20.0 g element X and 60.0 g element y then the percent composition of each element would be:
How can I find the percent compositions of Mg (NO3)2? - Socratic
May 15, 2014 · To find percent composition we need to begin by finding the gram formula mass of the #Mg(NO_3)_2# compound. Mg 1 atom x 24.31 = 24.31 N 2 atoms x 14.01 = 28.02
